Have my ARB compressor mounted under bonnet. When I run it, it takes the normal 8-10 seconds to pressurise the header tank up to 100psi. After about an hour or so, if you turn the compressor on (no hose attached), the header tank has lost pressure and a takes about 4-5 seconds to get back up to pressure.
This means that there is air being lost back past the piston somewhere. Is this normal for others with the same compressor? When I first got it about a year ago, it would hold pressure at least for a couple of days.Cheers,
Wazza

Mal B,
I only have the ARB compressor that has the small tank built on it for the air lockers.
I have thought about installing a larger tank but couldnt realy be bothed.
(maybe one day).

Mal / Kev,
The tank is as Kev says and built onto the top of the compressor for the air lockers.
The only reason I bought the question up is that I got a truck brake air tank yesterday from the wreckers ($20, excellent condition, including most of the air fittings and mounting brackets) and am going to plumb it in and mount it under the Cruiser. With the air being lost back through the compressor over time, I am needing either a one way valve or a stop valve to keep the air in the new tank and stop it being lost through the compressor. I have decided to go with a three way stop valve I have at
home. Tank is only quite small at around 15 litres.
Like Kev says, normally you wouldn't be bothered, but for $20 and 5 weeks holiday to fill in .... why not!Cheers,
Wazza

Wazza,
Make sure theres no rust inside the brake tank from condensation over the years.

Thanks Kev. It is all fitted and working sweet. Fitted with about 5mm to spare all around sitting under the front passengers
seat. Black oily residue coming out of the tank before I flushed it with diesel, so hopefully no rust problems.
Thanks all for your replies. Sounds like a bit of loss through the compressor is all normal.

Had an ARB compressor installed about 3 months. It's been the same from the day it was installed. Haven't found it to be any inconvenience.

Mine is the same, I have an air locker and when off roading I keep the compressor on and pressurised in case I need the locker, every half hour it briefly turns on for abut three seconds and repressurises the tank

I have had my ARB compressor for 6 years with and without lockers connected. The only time it leaks is if the air tank on the compressor is not fully tightened to the head or if the seal between the tank and head is damaged. Can also lose pressure when locker is on if the seals in your locker are worn.
The seal between tank and head is only $5 or so. Will hold air for up to a fornight when the seal is working correctly.
