I have a Stanley air compressor with a 25 litre storage vessel.
when I start it, it pumps up to 120 psi and then the motor cuts out.
Over typically 5 minutes, the air pressure will decay slowly to 80 psi
whereby the compressor motor restarts.
This happens when I am not using any air tools.
I have used a can of gas leak detector and tested all unions and joints
and I can confirm there are no leaks.
This then leaves the compressor pump bit itself... are they actually
gas tight or do they have a normal amount of leakage back to the air
inlet port?
I have two compressors with the same feature. I think you are expecting
too much for a modestly priced device. 5 minutes for 40 psi is rather a
lot although the initial pressure will drop as the compressed air cools.
Is your household insurer aware that you have a pressure vessel subject
to annual testing at your home?:-)
My understanding is that the requirement for annual testing is when
the pressure x volume exceeds 250 bar.litres
What about if you have multiple compressors that are individually under
the limit?
