Thread: Air Compressor Rebuild ??

Just crack the air line on the central valve block until you hear the hiss and then leave it until the hiss stops.

Or use your gap or rovacom tool and it's done in less than 30 seconds and you know it empty.

Has anybody fitted or considered adding a connection to the compressor or tank so you can fill tyres from it ??

It’s a low flow, high pressure compressor, completely the opposite of what you want in a tyre compressor.

ok makes sense, but what about if the tank reservoir ?

Clearly not to you.

You will burn out your compressor quick smart as it tries to keep up the air supply to the tank.

I say go for it and let us know...

The tank sits at 16.8 bar. A bit of plumbing required to make that work.

Aside from the previous comments on "don't do that, the compressor isn't designed for it" :

When the system pumps up, it brings air in, compresses it and pushes it through the dryer. When it farts, it takes that compressed, dry air and pushes it back through the dryer, ejecting some of the adsorbed moisture. It's a closed system.

If you go taking air from the closed system, you'll quickly saturate the dryer.

A quick calculation of my 255/55/R19 tyres would indicate a volume of somewhere in the order of 70L of air at atmospheric pressure (116L total volume minus 46L rim).

At 25psi, that's ~119L and at 40PSI that's 190L. So I'd need ~71L to go from 25->40 PSI.

The tank on the car is ~9L @ 16.8bar, so ~151L when full.

What do you define as a "topup" ?
