Not a good representation.. put the register on and then test it. The register restricts air also and would show less air flow, you basically tested a none restricted hole against a restricted one.
Even without a register, we can calculate free flow unrestricted register boot, based on data collected over the years. Standard stamp metal registers typically restrict 20-30%. If you take the higher number, 30% would be 36cfm subtracted from 120cfm. The delivered airflow would be 84cfm, which is higher than the battery-operated booster fan of 73cfm. If you look at the backside of the booster fan, there is very little open/free area get air into, let alone out of booster fan.
Yes, maybe if the manufacturer didn't restrict the back side of vent. There's very little free/open space to even let air into the battery micro fraction hp operated fans.
@@americantemperaturecontrol7852 Maybe it's the title of your video that is throwing me off. I clicked on it hoping to learn a bit more before purchasing a register fan for myself. I ended up buying one that plugs into a wall socket and it has made a huge difference for my situation. Your video makes it seem as if the whole concept is a scam and it simply is not. I have cold air in my vents, it's just not moving much due to other issues with the system. While awaiting repairs, the register fan has made my bedroom livable again. Maybe if you were testing a certain model fan that you listed in your title, then this video might have some merit. As it stands though, the video is very misleading and could lead some to exclude the option altogether. I'd still be sweating bullets trying to sleep if I went by this video.
I came up with the idea to put a fan over my vent on the top floor and the vent is located on the floor. My problem is that top room doesn't circulate enough area and heat obviously goes up. For my purposes I would just like a fan to pull air into the hottest room 24/7 during the summer and I installed a return vent over the door to let the hot air out so for me it should work great for that. I don't need it to boost air just to keep circulating area from the cooler downstairs.
@@americantemperaturecontrol7852 I'm sorry but this is clearly a scam. Nobody would use a booster that weak. Nobody at all. There's a reason why everyone is calling this fake. Try again with a real booster.
This seems like BS, a number of people are asking for battery powered fans, but the size of the battery would have to be fairly substantial or you’d have to recharge twice a month. Register boosters probably do suck, but this is a bogus demo of the Suncourt HC500 or another similar.
@@phxees I've used the plug in style in old buildings with bad AC design and they work great. It needs a healthy supply of cold air to draw from but they definitely work in the right situation.
@jeffjohnson1861 If you have a healthy supply of cold air, you wouldn't need a booster fan! What did you use to confirm the fan actually improved air flow?
I hate when people speak in absolutes. I have a room that barely got any air and it stayed warm during the summer. I installed a booster fan and now the room is more comfortable. Maybe a better title would be, "Why booster fans don't always work" or "Why some booster fans don't work well" or "Why THIS booster fan doesn't work".
It's a band-aid fix, sold by big box stores to homeowners that have no way of testing before and after to see if there's positive or negative effects/changes.
Educated beyond intelligence. Maybe put a register on the wall fornthe second test. It would score better than the fan assist. Plug the fan in on the first test, it beats both scenarios. What your doing is equivalent to measuring how much air comes through an open door on a windy day VS how much air comes through a door thats open 30% . Run your furnace and pull your filter with the blower running. Hear the difference? I hope you borrowed your friends tools and didn't know what you were doing, opposed to being a professional who is probably shafting people on energy audits
1. There is no plug to plug in on this fan... it's battery operated. 2. Your door example only works if there's a pressure differential and total number of holes/Freespass for flow. 3. Even without a standard metal stamped register, we can calculate 20-30% reduction in airflow which still out perform the booster fan.

doesn't the fan have to be on?
@@djghettofunk2530 booster fan is battery operated and was working as designed.
A booster fan is going to increase a low flow vent just due to physics. It's just that simple. This was a terrible demo.

That means you didn't need one to begin with.
Is that a battery powered booster fan or did you test it while it's not even on and boosting?
Yes, battery operated fan, and yes it was working.

You didn't put a vent cover back on.
Not in video.

I love those fake “reviews” 😂 First plug the booster fan into the wall, before testing LOL.
No cord to plug into the wall. It's battery-operated.
These guys might be the scam.
Would you like to explain your statement?
On the back of the one your reviewed you can see how much material is blocking airflow. Are they all like that?
For what I've seen and tested, yes.
Why would you use a booster on a register that doesn’t need it? It’s meant for a room that has poor circulation
It's a band-aid fix, sold by big box stores to homeowners that have no way of testing before and after to see if there's positive or negative effects/changes.
But that upsell at honeypot sounded soooo good
Intentionally dishonest review, or do you not understand that these booster have fans and require a power source?
They are battery operated fan
So creepy
This guy just wanted to show off his new Balometer, otherwise he has no idea about Physics.
Would you like to explain in more details? I would love to discuss the physics.
@@americantemperaturecontrol7852 Sure. Who would want to install a booster fan, which cost $60, without turning it on?
Educated beyond intelligence.

@@americantemperaturecontrol7852 Yes. Your video is a click bait. Cost me a couple of minutes for nothing.
the booster not even plugged in....NOPE
Your correct, its battery operated.
