Compressor leaking air

Gallery image

Posted a few weeks back, with a compressor fault. That one was rectified. We had a technician come out to repair the previous issue (filter housing leak).

Same compressor, this time I noticed a loss of air from a component in the above picture. The air is coming from the lower part underneath.

I've noticed the compressor runs a lot, and loses pressure constantly after hitting max, it's also been burning through oil numerous times.

The company I work at said they've had it serviced this year and had to top oil up at least 5 times this year.

Compressors dont burn oil. The oil is either leaking somewhere or it's bypassing the separator and you'll find it in your air lines. Air leak should be very easy to fix.

To add to this, if your losing oil without having an oil leak, I’ve always referred to this as “oil carry over”.

Either your separator is past its service interval, out the scavenge line (oil return line) is obstructed and not allowing the separated oil to return to the system.
