Under Bonnet Aircompressors

I'll second that. They aren't cheap but they are good.

My arb pump is in engine bay and is approx 15 years old not as fast as others but works everytime..

I looked for ages and really didn't want to buy another ARB as my old one failed. The AOB ones looked good. But in the end the ARB won out because it was the only one that was water and dust resistant and it was ok ( but not great) with the output.
2 things to watch with the ARB one though.
1)Their cut out switch is only about 100 PSI ( from memory) others are 150PSI. Important if you use a tank as you wont get as much air in it.
2)The connectors they use are only rated at 15A from the manufacturer and get REALLY hot / melt, even the wires get very hot. Replace the connectors with Anderson or similar. They work a lot better. It is a bad cheap design.

Boobook, "But in the end the ARB won out because it was the only one that was water and dust resistant", are you saying the AOB compressor was not water and dust resistant?

John, I am *pretty* sure that was the case. I told them I was putting it in behind the bull bar and they said that they didn't recommend that. I did really want to buy an AOB unit because their service was second to none. Great guys.

I asked 3 different ARB people including the product manager ( I don't usually trust what ARB sales staff tell me - every thing ARB is great. if you know what I mean) . All 3 said the compressor would work under water as long as the air inlet is above water level.

Dunno how true that is, but one of my compressors in mounted inside the bull bar covered in dust and river crossings. Touch wood it has been like that for 3 years. I also have one further up in the engine bay for extra air and just in case.

Boobook, my apologies, I thought you were referring to the AOB engine driven compressor, not the 12 volt one, oops.

That WOULD be the best option. i wonder if it would fit in a 200.

Edit. The endless air one definitely doesn't

:-(

In my 200 I have fitted the ARB (single) in the front behind the grill but in front and off to the side of the radiator so as to not restrict air flow..........works a treat.
