ARB Compressor Behind Rear Fuel Tank

[rwo Advanced Member Find all posts View Profile Close rwo]

Just wondering if anyone has mounted an ARB CKMA12 behind the rear fuel tank (obviously with the intake relocated into somewhere a lot less dusty)?

I am looking for a good location to mount the compressor but under-bonnet is out due to second battery, pre-filter and catch can. I wanted to put it behind the plastic panel on the rear LHS but after having a look at the area I'm not so sure, the mounting points don't seem strong enough and I'm not keen on drilingl holes in the guard. There is plenty of room behind the fuel rear tank and a few holes in the chassis that would work with a custom bracket to locate it right up under the floor and hopefully out of harms way, but I'm not sure how long the compressor would last if it were exposed to the elements/dust/water crossings? Power is also available from the seldom used Anderson plug on the rear bar and it would probably be the perfect location to plumb in a small air tank as well.

I'm also open to other suggestions for mounting locations...

rwo,

Behind the rear tank would be appealing for me too if I could keep it out of the elements. If it could be installed in a sealed box with a breather pipe that can follow the fuel filler neck to the top or even into the cab it would be a winner. Food for thought.

I've mounted mine under the bonnet on the drivers side in front of the master cylinder. There are 2 studs and a captive nut there so you don't have to drill holes, you just need to make a bracket. It's snug but it works well. I have dual batteries and am fitting a fuel pre filter as well so that was the next option. It's been there 2 years and never missed a beat and it's protected.

I like the idea of that but it a catch 22.
Yes it needs to be sealed to save it from the elements but it also needs some air to keep the unit cool when pumping.
If it were in a sealed alloy checkerplate box it would be like an oven when pumping 4 big tyres up!
Would like a little bashplate be enough protection?

Arn't they already a sealed unit, but I do like the bash plate idea? I'm not really concerned about damage to the unit as it can be tucked right up and out of the way and I would need to destroy the rear fuel tank, back of the chassis, towbar and bumper to do major damage in the area the compressor will sit (obviously apart from the odd stick that the bash plate should protect against). My main thoughts are how long the unit will last when exposed to mud, dust and the odd water crossing.

Craigo72 I have a diesel and want that location for the Provent, not enough room there for both.

I will email ARB and see what they say...

EDIT: Just read the specs again on the ARB site and it says "This water, dust, heat and shock resistant..." and further down says "Sealed for moisture and dust resistance", the question is "How sealed and resistant?"

I've seen them under ute trays getting absolutely smashed by sand mud dirt dust and rocks and they seem to hold up.

I'd still be looking at a small bashplate though.

Move the filter cartridge somewhere else and it'll be fine - a bit like a snorkel.

I like this idea..ive got portable ones but ive seen an under bonnet one in action and was impressed with the simplicity...

I too am of the opinion that they are sealed....can someone confirm this?

If you tuck it right up there is limited chance it will readily be harmed....

im seriously considering this....ive no room on the left side under my bonnett due to other upgrades.

A compressor by its nature sucks in air and then pumps out at a higher pressure, so they ae not sealed, no compressor is. If you put the inlet up high as others have suggested the rest of the unit should be OK.

Oh yea on top of rasing the air intake, make sure all your fittings are 100%.

Just imagine the compressor firing up for the lockers when your in the middle of that creek!

I guess the compressor could deal with a few droplets ok but if those threads arnt sealed 100% it might suck a biy too much in!

E-Lockers for me brother!

Compressor will only be used for tyre inflation, which (touch wood) I doubt I would be doing in the middle of a water crossing!

Finally got around to completing the install. For those interested check out my newly started build thread.
