Hi,

Any ideas were to buy a 12 volt fan, like an exhaust fan? Am thinking of fitting one to a ute canopy to see if it will assist in keeping dust out.

You could use computer fans.

I've installed a solar powered fan in the roof of a vehicle, been there for years now and still going strong. They are available from marine suppliers like Whitworths or Bias boating.
The only really successful way to kepp dust out is to pressurise the canopy area with a forward facing scoop which then forces the air out the gaps round the tailgate rather than sucking dust in. Doesn't work real well when travelling slowly either. What you really need is a fan to force air in so that the pressure inside is greater than outside, avoiding sucking dust in when you do so.

Now that's a good idea. Didn't even know of bilge fans until I looked at Witworths. Cheap as chips to. $20 gets me a fan that will do the job.

Thanks.

Also, have heard of Jayco camper trailer owners installing this type of set-up in the roof of their camper. But, because they are using the fan to force air inside to pressurise the interior, they use a circular air cleaner of a vehicle's engine to filter out the dust as it's being sucked/forced in.

any thing that sucks form inside to out will only increase dust infiltration.
You need to get a clean fresh airstream blown into the inside to put a positive pressure inside.

try the 12 volt shop

I had thought about fitting a tub from the outlet of the vents of the ute to help pressurise mine but so far it hasn't been warranted to do it. Run a tube up from the outlets and feed the air through the cab first. It may halp to keep the frige cool if the air was directed the right way.

Easy to fix and you dont need 12V or a fan.

Duck down to clark rubber and buy a few meters of their foam stripping and stick it to the inside bottom edge of your tailgate. This is where the majority of dust is drawn in. When you close the tailgate this will seal the gap. At least it does on a '03 Hilux.

I did 12,000km from Qld to WA and back via every dirt road, and with the side Canopy window open an inch had next to no dust in the back. Compared to the paint work which was bright orange by the time I got back.

Cheers,

Glenn.

Yep, totally agree with you Glenno, thats exactly what I did to my dual cab expensive about $10.00 a metre I used about 3/4 meters to do all round my'n is 30ml wide 10 ml thickness. Used it to seal up between ute body and canopy and also at the bottom of tail gate + I made up two bits of stainless steel pieces that I held with very small nut and bolts just inside of each side of vehicle so when I close tail gate it is sealed up down the sides as well. Plus used some door seal people put around the doors on your house just under the canopy rubber seal where you shut it + there is 2 drain slots right down the very front of the ute body just behind cab, these surprisinly let in some dust. Sealed them up with a bit of silastic. Mate no dust in mine. Just hope my gas bottle don't leak or I'm in trouble if there is any sparking going on up back. Take Care Steve M

Thanks everyone. Looks like I might just start with sealing everything and try it. Though a bilge blower is pretty damn cheap so might go the full hog and make sure.
