We did the Great Central Road in August last year, 1200km of dirt, and i can tell you Im so glad it some work on dust proofing the van. I sealed all underneath, every little hole i could find. I also positively pressurised the van with a sports air filter and a blower in the top fridge vent, worked like a treat at any speed.
Dust Proofing your Expanda ?

Hi Greg,
Could you please tell me where you purchased the sports filter and the 3" flexi tubing from. Did the sports filter have a model or part number?
Thanks Rusty
Hi @GregW
Nice work
Can you please tell me how/where the ducting entered the internals of the van from the back of the fridge?
Hi Relgate,
I drilled a 75mm hole in the wall next to the fridge, mine came out just under the water monitor. I used a 75mm hole saw, and then covered it with a wall vent plate from whitworths boat supplies. I will try and get you a photo.
Cheers
Greg

If your canopy has a window at the front, open it. That helps pressurise the canopy area and will limit dust. Works on mineCan anyone tell me how to fix the problem of dust coming into the back of a ute with a canopy? Thanks! Maybe take it to ARB or TJM to fix?
I have one of these to fit, just have to man up and cut that hole somewhere.

I want pictures !
I need ideas, I want to mount it on the roof where the clean air is, but then it would be eaiser and may be just as good (with a stone stomper) down near the draw bar pumping into the front tunnel, then into the van. But then Im going to mount the generator there......this is why Its still in the box.
EDIT
Here's a pic

I got mine from ebay on one of thoses factory clean out auctions listed as "working condition unknown". Listed as $150, I offered $75 and got it
its 12v too . Had to buy my own pre cleaner though.

I have spoken to the guys that sell these and they say that they work great for vans and to pressure seal them, only thing is if you want to buy a new one of these they are $1200 ex GST new then you have to get it installed or cut some holes yourself.
you got yours at a great price @ShaneT ........

Hey @ShaneT did you ever manage to get the positive air system installed? interested to hear feedback on if it worked and where you mounted it?
Hi all, have just placed an order on a 16-49-4 OB in preparation for a 3 month Vic-SA-NT-WA-SA-Vic trip from July - Oct next year. Coming from a soft floor camper trailer and after threatening to upgrade to an Expanda have finally done so, particularly thanks to the raft of great information on this site, thanks!
I'm building a list of modifications and one item on the list is dust sealing. Ideally we want to be able to tackle the gibb river road etc conditions permitting.
Apologies if I'm repeating other threads - I'm reading various solutions, including:
1. Sealing all gaps underneath the van, particularly hose and cable entry points and the potential big gap at the rear where the fibreglass meets the floor;
2. Ensuring a tight seal on the front and rear doors;
3. Covering the various vents; and
4. Positively pressurising the van via roof vent or other.
Given the the van will be fairly new, I'm keen to avoid the hole in the roof option if at all possible so I'm keen to hear how much success others have had at keeping dust out using the other solutions other than positive pressure?
From reading the various threads, I've interpreted that solutions 1 - 3 above seem to do a pretty good job at keeping the dust out without having to positively pressurise?
Cheers,
Shane

Hi Shane,
Welcome and congrats on the purchase.
12 months ago we travelled basically on the dirt from Bairanald to Mungo NP, Menindee Lakes then to Bourke via Wilcannia. This is roughly 600km. Whilst the Gibb River Rd is a different beast we still encountered bull dust etc.
My attempt at dust proofing was installing a home made hatch under the van to cover the wall mount A/C unit air intake through the floor and covering all passive vents with corflu and duct tape. I left the top vent for the fridge uncovered to allow heat to escape whilst on 12V. it worked well. On a rest break I went into the van to check for dust to find the kids bed having a fine coating but this was because the didn't close the window properly so make sure you do that.
