- Lomanco is the home of the one and only Whirlybird® Turbine Ventilator, the All Weather Turbine Vent. Whirlybird® turbines offer all of the essentials for energy savings and are geared toward going green.
Lomanco® wind turbines are available in three sizes-8", 12", and 14". The 14" Big Whirly turbine moves 37% more air than the 12". The 12" turbine is available in aluminum and galvanized finishes as well as a tile roof design.
Whirlybird® turbines are also available in two models-internally or externally braced. While the internally and externally braced turbines both have the same internal construction, the externally braced turbines have three braces that surround the outside of the turbine.
Im 31yo and I finally learned how this things work! I have seen them since i was a child, most of the time in stores or supermarkets, I thought they introduced fresh air but now I see they pump hot air out (since hot air goes upward) while making easier to cold/fresh air being introduced from the bottom (doors, open windows, etc etc)
I'm 27yo, and I know a little bit about conservation of energy.
But my dad insisted since my highschool days that passive exhaust fans exist, (as in the things you put on a wall of a kitchen etc)
I never believed him because if you have a hole in the wall, it's gonna help some smoke get out.
But if you put a fan in the way, the surface area of the hole reduces, and also you're adding a job to the air moving out, push the blades along the way.
I thought it's impossible.
Last month we had a warehouse built and it has two of these things. My dad told me they're passive exhaust fans. And they run without power.
I saw with my own eyes that they're rotating without any power supply.
I just had to google it.
Turns out conservation of energy isn't broken, there's just an additional force acting on it. The wind outside....
Thanks Lomanco ! We are thinking of installing multiple wind driven turbine vents very soon - this demo helped a lot indeed!
I've installed six of these on three houses either I or family members own over the last two years and love them. They stand up well to both high wind and the moderate rains we get here in California in the milder part of the year; I cover them in winter against heavy rain and to hold in attic heat. The sealed bearings assure that you don't get the squeaking you do in so many other cheaper models out there. A roof angle guage and clear instructions come with each one.
Properly functioning attic ventilation systems are required year around.
Most people associate attic ventilation with heat; however, of the two major destructive forces at work in your attic, moisture, not heat, is the most destructive. Since winter air is drier, it absorbs moisture from your home and you.
The attic space is even more susceptible to excessive moisture in the winter. Plus when air is trapped inside the attic - it will always be warmer than the air outside. The roof sheathing/decking will be colder in winter months. Thus creating even more condensation. It can literally "rain" in your attic. This moisture produces mildew, rotting conditions damaging wood members and destroying shingles or it drips down to the ceiling below to damage plaster or paint. Insulation also becomes wet and provides less resistance to heat loss - in effect loses its R-value.
This also shows why door vents/grills on bathroom doors are important to help bathroom exhaust fans work properly. Or alternatively, leave the door open a bit.
Love this video, I’m going to have these installed in my new house.
I rarely see people installing them or talking about them enough, it’s a shame!!
Not many people seem too focused on their roof space and the damage that can occur from heat and/or damp that is trapped in there.
And people love dark and even black roofs… I certainly won’t be having a dark coloured roof! There’s enough evidence to show dark roofs are hotter and don’t reflect the sun, it’s common sense.
Thanks for the good video!
Thank you.
What a great demo!
this video really made me realize to buy for my house, thanksss!
great Video For How to Work Roof Ventilator Systems Sir.
Every house should have this not just factories
We only manufacture Turbine ventilators for residential use.
Excellent. Very helpful. Thanks. God bless.
Glad you Like it!
great video..helps to see how the product and system should work....im buying three
Glad it helped
Do not forget to check the soffit inlets mine was only 1/3 on the turbines outlet areas, I have cut a 12” x 36” inlet area at the entrance ceiling and fitted a grill to draw more air to the attic. I can open the grill and fit a board / block it in the winter to keep the attic warmer during the cold month.

i always wondered what those things were on peoples roof xD nice to finally find out xD i use to think they were some sort of chimney opening xD
Now you know!
now put a dynamo in it and the electric product can be use to power fans inside the attic to make it more efficient !
I like the intro
Is it realy 100% waterproof?
What is the approximate lifespan for the finish on the painted turbines?
Wow!! 😮👀
is it still effective when the whirlybird and the intake are in the same side?
@LomancoVents how would three of these work on a 40x60 steel building garage? It doesn't have any soffits and is sealed. Maybe need a reversable exhaust fan to go with them?
Proper intake is a necessary requirement for any ventilation system to work properly.
Would just like to know if the rain water will enter inside the turbine? If it does how much water will enter inside the roofing through the turbine blade openings?
When turbines are properly installed with a balanced system of intake and exhaust, they should not allow any weather infiltration.
The turbine has twenty-one (21) air-foil curved vanes with rolled edges to deflect water. The rolled edges are designed to force the water to run down the vanes & not into the attic. Air-foil means a body designed to provide a desired reaction force when in motion relative to the surrounding area. To summarize, the turbine should be turning at all times when there is outside air movement.
The centrifugal force of the turbine also prevents leakage. Centrifugal force is the force that tends to impel a thing or parts of a thing, such as rain, outward from a center of rotation, such as the bearing/shaft assembly in the turbine.
It is important that the unit be sealed with roofing cement around all seams, nails, and under the flashing. The part of the flashing that is facing the roof peak should be installed underneath the shingles and the bottom part should be overlapping the shingles. Sealing in this manner prevents water from entering the attic under the flashing.
I live in Chicago in “split level” type home . Each of my two roofs is approx 800 sq feet . On each is three static roof vents with about 10 inch openings. I’m planing to replace them with Lomanco turbine or two . My question is “if I will buy 14 inch for each roof, is it gonna be enough and do I have to close other two existing static vents ?” Thank you in advance for answering

😎Me too
Whirlybird® turbine vents are a type of roof ventilation system that use wind to remove hot air and moisture from a building's attic or roof space. They are popular because they can help reduce energy costs and prolong the life of a roof by reducing moisture buildup.
If you are interested in purchasing a Whirlybird® turbine vent, you can find them at most home improvement stores, as well as online retailers. When choosing a Whirlybird®, it's important to consider the size and pitch of your roof, as well as the prevailing winds in your area. You may also want to consider the color of the vent to ensure that it blends in with your roof.
Installation of a Whirlybird® turbine vent can be a DIY project, but if you are not comfortable working on a roof or do not have the necessary tools, it is recommended that you hire a professional to install the vent for you. Proper installation is crucial for the vent to function properly and provide the intended benefits.
Can you make a sample at my house? I live in Indonesia, in a hot tropical climate, I really need this tool.. 😄
A neighbor told me as the heat rises, it makes the turbine spin faster. I think that is partially true but the turbine design has more to do with catching the wind to spin it.
You're correct in your understanding. While it's true that rising hot air can contribute to the movement of the turbine, the primary design of the Whirlybird turbine is indeed focused on catching the wind. The turbine's blades are specifically designed to capture even slight breezes, which then cause it to spin. This spinning action creates a vacuum that helps draw hot air and moisture out of the attic. So, while the rising heat may have a minor effect on the turbine's movement, it's really the wind and the efficient design of the turbine that are the key factors in its operation.
I have an attic that has no underlayment. If you into the attic you can knock on the tin. In the winter I have major condensation issues when it freezes outside. Would this stop the condensation?
if you have a defined attic space with intake and exhaust, our products will work well to remove damaging heat and moisture. Make sure you have intake vents located in the soffit to balance the exhaust. You will need to match the exhaust capacity and provide as much intake as you have exhaust.
Do these fans need periodic services or routine or preventive maintenance? And what is the life of bearings?
The Lomanco Whirlybird turbine is designed for silent operation and no maintenance. The Lomanco Whirlybird turbine is garranteed forever in North America. If it fails for structural or mechanical reasons Lomanco will replace it.
How much rain will come in through this type of vent?
+Michael Mixon Good question. I live in South Florida and installed 2 of these on my house in 2005. My concern was the same as yours in addition to the potential to stand up to hurricane winds and the possible noise from failed bearings. Did my research and Lomanco has sealed lifetime bearings and I purchased caps in case of hurricanes. My AC used to run from sun up till a couple of hours after sundown non-stop due to the lack of ventilation in my attic during the Summer. My electric bill went from close to $240 per month before installation to $130 after. Best investment I've made. To answer your concern, I've had no driven rain go through it nor have I had any leaks. The hardest part for me is getting on the roof and cutting a hole in your roof. Regardless of any manufacturer you decide to go with, I believe these things are the best way of getting ventilation in a roof at a really low cost.

@@stupadasso1964 If these things really do lower ac bills like that, I will look into getting this passed in government regulations.
Seems all systems or brands depend upon the intake, why didn't everyone talk about their intake part, only the vent part? Are "intake" part of the vents installation?
Intake is a very important requirement for the ventilation system. Unfortunately, intake is often overlooked. In fact, inadequate intake is the number one reason for the failure of an attic ventilation system. Lack of intake vents results in extreme heat buildup in the summer and severe moisture problems in the winter. Additionally, exhaust vents can actually become intake vents if no intake vents are present and pull in rain and snow. You must have a continuous supply of fresh air to “feed” the exhaust vents. The intake system must provide as much or more than the exhaust system in net free area.
what about a rain test, wind driven rain, will it leak?
Thanks for the comment.
Lomanco Whirlybird® turbines are Miami-Dade approved. One of the requirements is passing the wind driven rain test.
"Properly installed" turbines will not allow weather infiltration. with a balanced system of intake and exhaust, they should not allow any weather infiltration. As with any exhaust system, Whirlybirds must be part of a balanced ventilation system with intake & exhaust. They must be installed on the same side of the roof and at the same height. They should also be installed following the instructions.

I have recently rescued an injured whirlybird from the side of the road, and I am trying to nurse it back to health. What do I feed him?
Absolutely, let's have some fun with satire:
Hey there, rescuer of the injured whirlybird! Your dedication to nursing this inanimate object back to "health" is truly commendable. 😄
First things first, carefully and gently pick up your whirlybird and examine it for any "obvious injuries" like loose bolts or rust. After all, you wouldn't want your little turbine friend to have any mechanical mishaps.
Now, when it comes to feeding your whirlybird, it's a bit of a gourmet. Place it near the peak of your roof, where it can soak up all that lovely hot air and moisture. For a well-balanced diet, ensure it gets an equal amount of cool outside air from the lower attic area. Remember, it's all about that perfect temperature mix for your whirlybird to thrive!
In all seriousness, your whirlybird will be just fine as long as it's properly installed and maintained. If you have any real questions about it, feel free to ask, and I'll gladly assist you in caring for your home's ventilation. 😄
Is that a ridge vent working with the Whirly bird?
No, That is a cover for the ridge vent opening that is used when ridge vents are demonstrated.
a good product in 2013 but only okay on windy days so I'm thinking a combination of theses wind ones and the solar ones are the way we'll go
You want one TYPE of exhaust vent within a common attic area. Exhaust vents pull air from the easiest intake source. The use of two or more types of exhaust vents such as Power Vents with Roof Vents, Ridge Vents with Gable Vents, or any combination of exhaust louvers can make one of these vents act as intake for the other. Intake air should come from the soffit vent area to properly ventilate the total attic area and eliminate weather infiltration.
@@Lomanco solar powered whirlybirds
Can we set the air inlet from inside the room to improve the room ventilation?
Lomanco product are designed for attic ventilation.
how would it suck the heat from below? why would it turn when it's heat at the bottom? what's the technical behind this?
The concept behind wind turbine vents is that the turning blades will help force air out of the attic. Hot air naturally rises, so if attic air is heated above the ambient air temperature a vent will allow the less dense hot air to escape. The air being exhausted MUST be replaced by outside air drawn through intake vents located near the lower part of the attic space to properly ventilate the total attic area.
Hi mike, you said...if wind turbine does not have intake..so it not function properly...i saw in the demo...your intake is at the soffit...how about the vent hole intake is in the house...like at the living room...bedrooms...does it function properly? or
Intake air needs to come for outside of the home.
What if our window always open, isn't that enough for the intake? From Indonesia.
My roofing contractor suggested having 2 turbines installed just beneath the existing 1500 CFM Power Roof Mount Attic Fan (picture a triangle with a power fan at the top and 2 turbines at the bottom). I'm not sure such a system will work because the turbines will turn into intake vents, instead of exhaust vents, when the electric vent is on. I appreciate your advice asap. Thank you.

what about a tornado or hurricane?
Lomanco vents, including the whirlybird turbine series, that are marked or identified with "Miami-Dade Approved" has passed testing and met the requirements for use in the High-Velocity Hurricane Zone (HVHZ).
These attic vents are tested at wind speeds of 30, 70, 90 and 110 mph while having a rainfall rate of 8.8 inches/hour applied to the test deck and vent. The first three wind speeds are applied for a duration of 15 minutes and the final wind speed of 110 mph is applied for 5 minutes. The testing is performed by a third-party laboratory that must be approved by Miami-Dade County.
We also sell hurricane caps for our turbine vents if needed.

Can you use this as a passive smoke extractor for a kitchen?
Use as a smoke extractor will void the warranty. The Lomanco Whirlybird is not designed for the purpose you mention.

Could this product be clanged to generate electricity for high wind cold areas home with no attic?
It is possible to retrofit turbine ventilators to generate electricity, but whether or not it's practical or cost-effective will depend on several factors.
First, turbine ventilators are typically designed to ventilate hot air and moisture out of an attic space, so if you don't have an attic, you may not have the necessary airflow to generate significant amounts of electricity. Additionally, turbine ventilators are typically passive devices that rely on wind to spin the turbine and exhaust hot air. To generate electricity, you would need to install a generator or alternator to convert the rotational energy of the turbine into electrical energy.
Assuming you have enough wind to spin the turbine and generate electricity, the amount of electricity you could generate would depend on the size and efficiency of the turbine and the generator or alternator. You would also need to consider the cost of the equipment and installation, as well as any regulatory or permitting requirements.
In summary, while it is technically possible to retrofit turbine ventilators to generate electricity, it may not be practical or cost-effective in all cases. If you're interested in exploring this option further, you should consult with a professional contractor or engineer who has experience with renewable energy systems.

My house is townhouses is flat roof, no intake what can I do ?
If your townhouse has a flat roof and no intake vents, you may want to consider installing exhaust vents to allow for proper attic ventilation. The lack of intake vents can result in poor air circulation in your attic, which can lead to a buildup of moisture, heat, and other harmful elements.
Exhaust vents can be installed on the roof to allow for hot air and moisture to escape from the attic. Some common types of exhaust vents include ridge vents, turbine vents, and static vents. It's important to choose the right type of vent based on your roof design and the amount of airflow needed.
You may also want to consult with a professional roofing contractor to determine the best options for your specific situation. They can assess your roof design and recommend the most effective ventilation system for your home.
What happens if you add an electric power vent to an existing roof ventilation system that does not have enough net free space (Can it be used to increase the efficiency of an under ventilated (outtake) roof system - Most commonly seen in small hip roofs with a small ridge line. - basically, my question is... I know it's not okay to mix ventilation systems.... but can a power vent be utilized in a situation such as this where a small ridge vent is installed... BECAUSE of the lack of net free space on the outtake. (If not.... what should the homeowner do? Be okay with the small ridge vent and "accept the fact" that it's a bit under ventilated on the outtake? Or cut a bunch of box vents into the home and get rid of the ridge vent?
Lomanco does not recommend mixing two different types of exhaust vents on the same roof above a common attic because it could result in short-circuiting the attic ventilation system. Without knowing your exact situation, perhaps you could block off the ridge vent and use ONLY Power Vents as the exhaust.
Does this remove dust?
TheLomanco® Whirlybird® Turbine vent was designed and tested to provide ventilation for an attic space by removing air containing heat and moisture. No testing was done for dust.
But what is the difference between the internal and external brace?
Internally and externally braced turbines both have the same internal construction, the externally braced turbines have 3 braces that surround the outside of the turbine.

What if you only have gable vents?
If your home only has gable vents, these can still be effective for attic ventilation, but their efficiency largely depends on their size and placement, as well as other factors like wind direction and air volume in your attic. Gable vents are installed at the peak of the gable ends and allow air to flow through the attic.
In the case of having only gable vents, it's crucial to ensure they are adequately sized for your attic space and are not obstructed by any insulation or other materials. If you're finding that your attic is not being ventilated effectively with just gable vents, you might consider using a different vent type, such as ridge vents or a turbine vents like the Whirlybird, to improve airflow. The ventilation system needs to be 50% intake and 50% exhaust. It's always a good idea to consult with a ventilation expert or roofing professional to determine the best setup for your specific home.
Is it available in germany?
Do i have to stop it from working in winter? I only want to let the heat go out in summer.
No. Properly functioning attic ventilation systems are required year around.
You should not cover or block your exhaust ventilation in the winter.
Most people associate attic ventilation with heat; however, of the two major destructive forces at work in your attic, moisture, not heat, is the most destructive. Since winter air is drier, it absorbs moisture from your home and you.
The attic space is even more susceptible to excessive moisture in the winter. Plus when air is trapped inside the attic - it will always be warmer than the air outside. The roof sheathing/decking will be colder in winter months. Thus creating even more condensation. It can literally "rain" in your attic. This moisture produces mildew, rotting conditions damaging wood members and destroying shingles or it drips down to the ceiling below to damage plaster or paint. Insulation also becomes wet and provides less resistance to heat loss - in effect loses its R-value.
Will this work against keeping heat in???

The centrifugal force of the turbine also prevents leakage. Centrifugal force is the force that tends to impel a thing or parts of a thing, such as rain, outward from a center of rotation, such as the bearing/shaft assembly in the turbine.
It is important that the unit be sealed with roofing cement around all seams, nails, and under the flashing. The part of the flashing that is facing the roof peak should be installed underneath the shingles and the bottom part should be overlapping the shingles. Sealing in this manner prevents water from entering the attic under the flashing.
How storm affect this?
When turbines are properly installed with a balanced system of intake and exhaust, they should not allow any weather infiltration.
The turbine has twenty-one (21) air-foil curved vanes with rolled edges to deflect water. The rolled edges are designed to force the water to run down the vanes & not into the attic.

Does 14" fit on this smokehouse
No.
And if you don't have any wind like in Houston, you're screwed and will still stay 150 in attic.
Maybe check that you have the required amount of intake ventilation installed.
What about winter?
Do NOT cover your Turbine vents in the winter. Properly functioning attic ventilation systems are required year around.
Most people associate attic ventilation with heat; however, of the two major destructive forces at work in your attic, moisture, not heat, is the most destructive. Since winter air is drier, it absorbs moisture from your home and you.
The attic space is even more susceptible to excessive moisture in the winter. Plus when air is trapped inside the attic - it will always be warmer than the air outside. The roof sheathing/decking will be colder in winter months. Thus creating even more condensation. It can literally "rain" in your attic. This moisture produces mildew, rotting conditions damaging wood members and destroying shingles or it drips down to the ceiling below to damage plaster or paint. Insulation also becomes wet and provides less resistance to heat loss - in effect loses its R-value.
a thermostatic activated fan will do the same venting cheaper
How can anything be cheaper than the power of the wind?
Ohhh he got you there 1985fatAL
Lol you just got served up a dose of " for real" . Unless electricity is free for fats.
Also with the turbine, there are no electronics to fail. Simplicity is much better.
That small space should have been sucked clean in seconds.
I’m not sold on how great it is. It’s free venting but really not sold on how good it is.

Well if you consider the other types of vents which are more static, this forces out air a lot better and you can't argue that.

Big problem, there is no heat in the smoke house. The comparison is flawed.
Whirlybirds work in both cold and hot weather.
I'm going to put one on the roof of my car to help get the farts out quickly so passengers stop gagging and screaming.
While it's understandable that you're looking for a solution to improve the air quality in your car, installing a whirlybird turbine vent on the roof may not be the most effective or practical approach. Car ventilation systems are designed to circulate fresh air and eliminate odors efficiently. Here are a few alternatives you can consider:
1. Open the windows: Rolling down the windows while driving allows for better air circulation, which can help dissipate any unpleasant odors.
2. Use air fresheners: Utilize air fresheners specifically designed for cars to help mask any unwanted smells. There are many options available with various scents to choose from.
3. Regularly clean your car: Keeping your car clean and free from any lingering odors is essential. Vacuuming the interior, using fabric fresheners, and regularly washing the car's upholstery can help eliminate smells.
4. Avoid foods that cause strong odors: Being mindful of the foods you consume while in the car can help reduce the likelihood of strong odors. Opt for less pungent food options when traveling with passengers.
Remember, good communication with your passengers is important. If someone is uncomfortable due to unpleasant smells, politely addressing the issue and taking their concerns into account can go a long way in making everyone's journey more enjoyable.
It looks pretty lazy moving air even in that tiny area..So install those every 2 feet, like 100 of them maybe will do some flow..LOL
Lomanco has several resources available to help determine how many vents are required for you attic space. There are calculators on various product pages on the website (Online Calculator). We also offer a Ventilation Calculator chart in our Product Catalog and turbine flyer.
What about if there's no wind 😏
Properly installed turbines should be spinning with minimum wind speed. Every turbine is tested to spin at a wind speed of 3 MPH before leaving our manufacturing facility.
There are several factors that influence the the efficiency of a turbine. Turbines will work at maximum efficiency when the top of the turbine is over the roof peak. This will allow the wind to hit the turbine for all directions. The turbine also needs intake vents with an obstructed path to the turbines. Without intake vents, the turbines do not have a continuous flow of make up air. Mixing exhaust products will also have an adverse effect on the turbine. When multiple types of exhaust products are used, the chimney / stack effect is negated and the turbine does not draw from the intake as well.
If the turbine spins when you turn it by hand, but not when the wind is blowing, the bearings are probably worn out. If the bearings have gone out, contact customer service (800.643.5596) for warranty information.
Sorry, not big fan of cutting 5 to 7 holes in my roof. Potentially roof leaks, and no wind there not moving. Also bearings fail, its moving part.
Yeah but have you seen ridge vent holes they are massive holes across the entire roof.
No single ventilator suits every situation. Our company produces a comprehensive range of residential and light commercial attic and crawlspace ventilation solutions. Our product lineup is categorized into seven types: Turbines, Roof Vents, Power Ventilators, Ridge Vents, Gable Vents, Intake Vents, and Foundation Vents.
I have 2 installed on a small 3 bedroom home and they are next to useless, the Australian summer is way to strong for these things to do any significant cooling to the point we felt no difference inside the home and barely noticeable improvement on ceiling temps using infrared temp gauge. As they say " about as useless as tits on a bull"
Installing the Lomanco Whirlybird is only half of a complete ventilation system. To have a properly functioning Ventilation system you must have proper intake. The air being exhausted MUST be replaced by outside air drawn through intake vents located near the lower part of the attic space to properly ventilate the total attic area and eliminate weather infiltration.
-Each 12” turbine requires 259 square inches of intake ventilation
-Each 14” turbine requires 345 square inches of intake ventilation
Did you have intake vents in your sofits as required/advised by the author of this video? I too am thinking of putting whirlybirds on my house, but if they're as useless as titts... then I'll save my time, money and effort instead.
@@nickblets69 sure did Niblets, I put the vents on the cooler side of the house can feel the air being drawn through into them but the amount is being drawn through is not much compared to the size of the roof cavity and we only have a 3 bedroom single story house. Would compare it to trying to empty a swimming pool with hose not much larger than a drinking straw. Much better results with solar roof vents as motor fans draw so much more air through like proper venting of a confined space. We have roof vents on the garden shed and that's where we see better results from them in a smaller space.
@@hoopshooper9102 ok. Thanks for the quick reply. Does your house have decent amount of insulation to prevent heat radiating from the attic through your ceiling and into your living areas? Maybe most of your heat is coming through your windows.
@@nickblets69 also we live in Australia where it gets pretty hot during summer and not much of a winter as such.
The problem with it is it makes your roof ugly.
Perhaps one of Lomanco's other ventilations products would cure your problem.
So... I have to watch a random ad from UA-cam to watch your ad about your product? Not a great start, Lomanco.
We have no control over UA-cam ads. Sorry.
they don't work
I can assure you that when the Lomanco Whirlybird® is properly installed and part of a properly installed Ventilation system( which includes proper intake) they do work.
Of couse they do...it's simple physics
The disparity of the ridgevent and the whirlybird is very evident. The demo is not accurate.
Exhaust products are part of a ventilation system. As long as the proper number of vents are used and the system is balanced, (50% exhaust and 50% intake), ridge vents, roof louvers, whirlybirds, power ventilators or gable vents will be equally effective. All of Lomanco's products are designed with the Lomanco Balance in mind- free movement of air and weather protection - and are equally effective. Often, the design of the home will determine what type of vent is used.
ridge vents are better everything else does not work in real life
Have you had any specific problems with other vents?
Nothing against this product, just the scale of the demo. You have an actual size Turbine evacuating smoke from essentially and ant sized house. Just saying...
Yes, as we state it is a dramatization.
