If the valves were installed with the correct orientation, if the piston rings are seated properly, and if the tank check valve is operating as it should, then it is likely that a pump gasket is letting go at the 60 PSI level, allowing air to flow back and forth between high and low pressure, without being driven down into the tank. Replaced cylinder sleeve and piston ring, still 60psi max. To conduct the test, first empty the air tank. Next, check the air filter to see if it needs to be cleaned or replaced. Also, an air compressor will not build pressure when the inlet valve doesnt open completely. The Central Pneumatic compressor line is also available on line, and through select distribution in other countries.

Ill try rebuilding or replacing the intake valve and see what happens. The differential pressure of compression systems is the variation between the cut-in and the cut-out pressure. 1. Instead, our air compressor troubleshooting techniques in this guide can help to detect loss of pressure. Start the compressor. If this valve has failed, air will flow into the line to the tank, but as soon as the piston moves into the intake cycle, air will still flow into the piston from the intake valve, but it will also back up the line from the tank into the piston bypassing the pressure valve or flapper. However, this guide will expand your technical skills and explain more ways of resolving pressure issues. 2. If you look closely at the compressor, and compare it to many on the market, you will find that the style and external components are common to many makes.
