Hi Alister Love your work. I was so happy to find your video as I have been looking for a simple solution as you have presented I have one question regarding our van has a small scupper over our bed which I’m not sure if I should open this device also when on dusty roads? Do you have an opinion in this regard. Again thanks for all your insight Cheers
If there is no filter behind the scupper vent, I'd most likely keep it closed. It depends if you would be getting clean air. But, if you pass someone on dirt road coming the other way, chances are you would scoop in a lot of dust.
If I had the money. plus the electricity supply needed, I would go the Carafan. But, I went this option cause I couldn't afford the cost, nor the installation. I do not have the roof space for a carafan as I've maximised the solar on the roof. It worked well, but the lower screen came away and allowed bulldust to get behind the filter. Future fix will be to increase the filter area, plus put a filter over the fan intake, so if bulldust gets in again, it wont get past the 2nd filter on the air pump. Oh, no, we did not get any dust inside the van.
Great effort. Have you tried it out? Does it generate sufficient positive pressure? In very dusty conditions I am wondering if your filters will get clogged, not a lot of surface area?
Good job on that positive fan . I was just wondering that fan works as soon as you plug it into your car 🚗. Just curious if I missed something. Take Care.
Ive done the same but what i did was use a car air filter on intake side of the blower and used a cabin filter attaching aluminum gill to hold in place with wing nuts and bolts for easy replacement of filters also used marine grade stick on sponge seal
When I open the door with it going, I notice an increase in fan noise, proof to me that the fan is pressurizing the van when door closed. I'm yet to travel on dirt roads.
My only concern is that all the Blowers I have looked at, including the one you have used, say that "Continuous Duty" means running for no more than 20 minutes non stop. Not sure how you will get on with it running non stop.
G'day Allsiter, looking at doing similar when I cam across your video, have you managed to test if it works okay? Also what Brand and Model Bilge fan did you use and do you know CFM rating of it?
Hi, fantastic idea for sure I have the 100mm fan it is rated at 275CFM it really moves the air I was quite surprised as to how strong it is. My question is pretty much the same as everyone else's really, have you tested the idea does it work? Have you had any problems & if so, what were they? I have no room left on my roof for a Dometic or a Sahara, so I pretty much have to give this a shot. If you were to do it again what would you do different, how & why? Any pointers you can give me, would be very much appreciated. Garry.
Hi Garry, Yes I would do it again, however would use an AC filter which has a larger surface area. I've added a switch to turn it off so it doesn't wear out whilst on the blacktop. No haven't tested yet, but I'm confident it will work even better than the dometic, which relies on movement to generate the air pressure.
Hi again, I have made a little progress with my dust suppression filter the K&N RU-2590 fits my 4inch Seaflo blower & cavity space in the van perfectly, the K&N can be taken off & cleaned out & re oiled for the next trip. Regards, Garry. @@PinkysTravelAdventures
The ducting goes into the van. There is an air pathway from the top grill to the lower cavity, so if the filters in the bottom block, it can still suck air through the top filter (like a backup).
Both vents are required by the fridge cooling system Cold air comes in the bottom and is drawn up through the cooling fins at the top By reducing the intake ( the bottom vent) the cooling efficiency is affected Simple fridge knowledge so by no means " not needed" Would have been a better location towards the front of the van as there's less dust above wheels
Thanks for the info! however, being a compressor fridge it doesn't need as much cooling/circulation as a 3 way. The air being forcefully sucked into the cavity behind the fridge is still available for the compressor cooling at the top vent.
Hi mate My name is Sam. I’ve watched your segment on the dust reduction system, Just wondering if you’ve used it in your travels. Has it worked what you have expected ? Either way can you give me feedback on it please. Thank you
Let’s hear it for the algorithm. I started searching six months ago for information on dust reduction, and this video finally popped up on my feed.
Thanks, good luck with your solution.
Great video and very helpful
Glad you think so!
Great job
Well done 👍🏼
Thank you 👍
Hi Alister

Seen your video looks great have u given it test on dirt roads as yet.also i too have compressor fridge so you said the bottom vent isn’t required?😎
Hi, thanks. Yes this is proven by the new ATs not having that bottom vent.
@@PinkysTravelAdventures cheers let us know how the in-line fan goes with dust am very interested,safe travels
So how does your dust reduction system go. would you still recomend doing it like this or go the carafan
If I had the money. plus the electricity supply needed, I would go the Carafan. But, I went this option cause I couldn't afford the cost, nor the installation. I do not have the roof space for a carafan as I've maximised the solar on the roof.

Oh, no, we did not get any dust inside the van.
Was the aluminum filter mount plate just taped to the plastic grill or did you also solid attach eg screw it ???
Taped around grill with duct tape, plus sika the gaps where tape would not stick.
Great effort. Have you tried it out? Does it generate sufficient positive pressure? In very dusty conditions I am wondering if your filters will get clogged, not a lot of surface area?
Hope to go for a dusty drive this weekend. Will see. Based on the Dometic DRS any positive pressure is better then none.
Can’t wait for an update 👍

Good job on that positive fan .
I was just wondering that fan works as soon as you plug it into your car 🚗. Just curious if I missed something. Take Care.
Yes it does, I've run its power cable to the Car input on the Van BMS, so when van plugged into truck, it gets power straight away.
@@PinkysTravelAdventures thanks again for showing us how you did that,great job.
So, after having it for over a year, does it work on gravel roads?
yes, its on a switch now. So, turn it on and works great.
so whats the verdict, did it pressure the van and keep the dust out? did you have to go around the van and seal up all the other holes Jayco drilled??
Haven't been on any dirt roads yet to really put it to the test, but it does pressurise the van, so it's gotta reduce any ingress in transit.

Great job Allister, but you need a workshop 😂
I do! But you work with what you have..
Ive done the same but what i did was use a car air filter on intake side of the blower and used a cabin filter attaching aluminum gill to hold in place with wing nuts and bolts for easy replacement of filters also used marine grade stick on sponge seal
Yeh, like the idea. I will probably make a better filter later.
Did yours work well ? So far no one has indicated that this idea works
When I open the door with it going, I notice an increase in fan noise, proof to me that the fan is pressurizing the van when door closed. I'm yet to travel on dirt roads.

Yeh, I've now changed mine so it's on a switch, I turn it off when on blacktop.
Great idea, have you put it to the test yet. If it works l would like to do the same thing but with bigger filters.
Hi, not been able hook up yet. hopefully in the next two weeks.
@@PinkysTravelAdventuresany update on how it went?

Not yet tested, been too busy with work. The Seaflo 75mm Blower moves 122CFM

Thanks, might get one to put on, double filter then.
I would have put the fan in the top vent, otherwise a good job.
There is not enough space in the top for a fan, that's where the fridge compressor is.
@@PinkysTravelAdventures maybe you could have run the ducting to the top vent.
The ducting goes into the van. There is an air pathway from the top grill to the lower cavity, so if the filters in the bottom block, it can still suck air through the top filter (like a backup).
Yeah fan should have been in top vent
Both vents are required by the fridge cooling system
Cold air comes in the bottom and is drawn up through the cooling fins at the top
By reducing the intake ( the bottom vent) the cooling efficiency is affected
Simple fridge knowledge so by no means " not needed"

Hi Sam, Yes works fine. Haven't tested on dusty roads as yet.
did you actually get around to testing it on dirt roads every bodys waiting for your answer
Sorry, no dirt roads as yet.

they are a complete scam
Most people wouldn't need one.
