Hey all,

Just picked up the newish ARB air compressor and i must say that i'm impressed with it's performance...how they can increase output and make the darn thing smaller is beyond me...lol. The switch and auto shutoff when not filling are great additions.

Anyway, after reading about the issue, and testing for myself, i have found that the sleave to disconnect the air hose gets VERY HOT......Even the hose gets very warm for the first 1m.

Has anyone modified their compressor to eliminate/reduce this issue (protection etc)?

Any tried and tested ideas?

Hi Andrew.
I have the same problem with my compressor.

Hope you receive some helpful replies.

Hi Andrew,

My husband brought an ARB Compressor I think it was thier newest model, anyway it came in a plastic looking tool box. Inside the box there was a pair of suede leather gloves, and silly me I just had to ask what they were for. I'm now informed that my husband will be wearing them so that he doesn't get burnt when using the compressor.

lol, they don't come with gloves normally IIRC, so it sounds like a known issue.....i'm sure the old one didnt have as much of a problem.

i'm not into the glove concept myself (dont fit everyone etc) so would rather see a "fix" to the issue.

Let him learn the hard way like the rest of us Andrea .... LOL

See if you can get the hose from a MaxAir. The coupling from that is covered with a rubber sleeve.

That was the only thing that made me choose a MaxAir over the ARB.

cheers

I'm not sure which part you are meaning (i'll google for a photo), however the ARB one HAS a rubber (orange) sleave over the hose side (which still gets very hot), however the female connector is on the compressor (as usual) and it is this which gets very hot, very difficult to remove like this.....and unsafe IMO for unwary users/bystanders.

Unfortunately, heat is a by-product of compression and the more compression you have, the hotter it gets. I don't there's a way around the physics unless you reduce it's capacity (and we don't want to do that). So, I agree with the thoughts above that either gloves or insulating with rubber or similar is about the only option. Maybe it's a good excuse to have a refreshment while you're waiting for it to cool down :)

Oops - that should have read "I don't know that there's a way around the physics....". Fat fingers :)

I take it you don't know what gloves are for.

Yes, this appears to be a common occurrence Andrew.

My "Big Red" has a similar "problem" but because it remains in the carry box, I leave the hose connected to the compressor end and just close the lid. It only takes a couple of minutes after last use and you should be able to safely handle the connection.

Disguising it with a rubber cover doesn't sound like a good idea to me. Better to have the coupling exposed to the ambient air to assist cooling.

Thanks Bill, the new design (more-so the hose setup) means that you cannot close the lid without disconnecting it completing ....unlike the older version IIRC.

I was hoping for a solution like heat resistant tubing etc, yet don't know where/if it exists etc.

Nice to know that other compressors have a similiar issue... :-)

My ARB compressor is permantly fitted in the back of the cruiser in a position that is a bit difficult to get to. I have removed the fitting on the top of the compressor, replaced it with a 90deg bend, and then put on a 1m length of compressor hose with fitting on the end. I have fixed the end of the extension hose to the side of the storage drawers below the compressor switch. I connect the compressor hose to the end of the 1m extension - heat problems gone and much easier to connect/disconnect.

Hi Andrew,
What I've done is... I used a small fire extinguisher tank 1/2 cfm and welded - silver solder - appropriate fittings to both ends of thank and woala.... I plug my hose at the end of tank and NO Heath...... Workes for me. Use it last 7 years without any hasle.
Hoppe this helps...

Although mine is not an ARB compressor they are all much the same getting very hot at the outlet. I've fitted a short hydraulic hose with crimped fittings into an alloy air manifold. This ensures that even after long duty cycles (30 min +) that heat is dissipated well before it reaches the brass disconnect fitting. My suggestion is to either fit some kind of heat sink or heat proof hose directly to the compressor outlet.

Thanks for the idea..might have to get some hose installed.

Andrew you can get braided steel line for these to act as a heat sink before it reaches the fitting and air hose. In some compressor trials the hose got so hot the fitting blew off so its not isolated case.

The foot of braid allows a surprising amount of heat to dissipate and is simple to install. Its the same system they use on truck air systems... old ones had copper pipe straight off the compressor to the wet tank and now most have braided line in that section.

Matt.
