Dust free pressurised camper box, (KK style) ?

Thanks Andrew, will follow up.

I think they were for a Briggs and Stratton engine - I'll find the manual if you like.


Tim

Thanks Tim, I downloaded a catalogue of various mower filters from www.gaspares.com.au last night but haven't seen the same filter yet.
If you can point me to a particular model it would be useful.

Rob

G'day Rob,

I dug out the Kimberley manual (2005 version) - The paper type filter is a Briggs & Stratton part number 491588. There is also provision for an oiled foam piece, part number 805267 (B&S) or 'Rotary' air filter 19-8480.

Hope this helps - and that they are still available!


Tim

Tim,

Thanks again, two of those PN's you quoted are listed in the "mowers-air-bat_1-29.pdf" file I downloaded from the GA Spares website (mentioned above).
This gives me some more pieces to the puzzle.

Thanks for your help!!

Rob

Thanks RA, looks promising.

Mandrake,

Thanks for the pointer, I've used some of these filters with PC's over the years. I thought that they were useful but wondered about their ability to stop dust as compared to 'fluff' etc.
I'll give them a more thorough look.

Rob

My son does PC Case modding - he uses the steel mesh flyscreen cut to size and then the sponge - That seems to work for a PC in an office - But I don't think there's a fliter built that can withstand bulldust and corrugations ...

I have seen a similar system employed to keep the engine compartment of a rear engined coach clean.

An air intake was mounted on the roof of the bus right at the front and this was ducted to the engine compartment. No filters just pull in the air where it is clean.

If I am the lead vehicle I keep the vents on the car open all the time except when I encounter oncoming vehicles. Provided I remember to switch the ventilation system to recirculate before the dust arrives and go back to fresh air once it has cleared I have no problems with dust.

Bungara,

Thanks for providing me with the benefit of your experience, it helps me to consider if I'm going overboard here.

Your ute is a very nice setup, very professional. By the look of the construction of your 'box' I'll bet that those doors seal very well, so well that hardly any air would be getting by the seals.
I'm just guessing here, but if this is the case it would mean that little air is coming in your roof scoops and therefore little, if any dust.

As you say that you have 2 fridges in there that work well so I can't argue with the facts.
My 'box' is quite a bit smaller than your unit so I wonder how well it will shift the heat from the fridge, especially if the unit is stationary for a day in the sun (wouldn't need filters if I was stationary though).

I also believe that the simpler I make things the more reliable they are.
Maybe I'm creating a mountain out of a mole-hill.


Although not quite the same situation, I also own a dual-cab ute that has a canopy with a rooftop vent. Generally speaking, having the rooftop vent open when travelling will keep out most of the dust fro entering via the tailgate.
After our trip from Vic to the Simpson this year we had to re-think our strategy as anything that was exposed in the back of the ute got dusted and we mostly travelled solo.

thanks again,
Rob

You are correct in assuming very llittle air comes in...........the movement forward maintains the rammed positive pressure hence no dust.....and yes the seals are very good.

As for the temperature when being stationary........I lined the interior with an aluminium insulation from Bunnings and we have been able to keep fruit in a open top box on the top shelf (about 350mm clearance from roof) with no problems at all......and we have been in very hot weather at times....it has really surprised us how effective this insulation is

Our previous dual cab that had a canvass canopy with an air vent pocket on both sides at the front so that once again air was rammed in when travelling and worked reasonably well for dust although as we all know the tailgate area allowed some dust in...........This canopy was lined with weld mesh sides and so when stationary we were able to lift up the sides for air flow and maintain security

When I changed to the solid box I was a little concerned about the stationary heat but it has been a non event with with the top shelf above the fridges and the insualtion all round

cheers

I am interested in your set up Bungarra.
What sort of insulation did you & how did you fix it?
Did you insulate the roof only or the whole canopy?
What type of vents did you use? Are they those marine type with water dispersers?
Peter

Hi Peter

The insulation I used was about 3 or 4mm thick in a sort of cell formation..comes in a roll of about 900 wide I think it was......sorry I cant recall the brand name...but it was readily available from Bunnings.....if you cant find it I will have a look when next in town and tell you the specific details of it...let me know if you wish me to do so

I fixed it all round with a liquid bonding agent..wasnt liquid nails but something similar and fast grab....works a treat

As for the air scoop there is only one in the center of the roof at the front..........very similar to the Police paddy wagons sort of half a football shape and so no water ingress.....once again dont remember the name but can probably check it out if you wish

cheers

Graeme

Thanks for that Graeme.
I haven't built my box yet & it is great to get a bit of an insight into how others did it & got on. It will have insulation when I build it. Good to see that 4 mm works.
Thanks for starting the thread Arjay

Slim,

I am modelling my setup from another bloke's. He has fitted a vent (with fan) on the front the the box but at the bottom, right near the base of the cab (79 series) and an exhaust vent at the back of the box (top).
I think that the air pressure at the front vent while travelling is enough to move air through the box, the only problem being that dust works its way in also.

I want to be able to stop the dust while mobile but also vent the box if req'd when stationary.
If I move the front vent up higher I may be able to virtually eliminate the dust.

As mentioned above in my reply to Bungarra, I also own a dual-cab ute and know about the associated dust problems. I believe that others on this forum have fixed this problem by attaching strips of foam around the tailgate area to help seal the gaps.

This box will be a semi-permanent fixture on the yota as it bolts onto a custom tray. The slide-on camper will be removable.

x2 on Donaldson Filtration. They have a range of specialised filtration solutions for this kind of application.
Their staff are also very helpful and knowledgeable.
No connection with them.

Thanks Vince, Kiwicol1 & Ross, I will look into these.
