How To Fix Air Compressor Regulator

The regulator has to be readjusted to maintain set pressure even when using very small amount of air.

How to fix air compressor regulator.

Been meaning to do this for years but sin. This regulator part flexes constantly as the compressed air flows through the regulator body fluctuating to exert more or less pressure on the internal spring of the regulator as it works to maintain a constant downstream air pressure at the regulator setting. A friend was going to toss this in the trash because of a bad regulator. The item inside the regulator that keeps the air flow from leaking out is the diaphragm.

It s actually venting the residual pressure from the compressor head so the motor doesn t have to work as hard on the next startup. The air compressor unloader valve is what makes the psssssst sound when the motor shuts off after reaching operating pressure. Connect the air compressor to the power and turn it on. Fix an air compressor regulator for under 10.

Connect your tool to the air hose and connect the hose to the air compressor. Air compressor repair can be simple. Well life happens and i ended up with a new job so this sat for two years. The air capacity of the compressor depends on the size of the unit and commonly runs between 100 and 200 psi per square inch.

If i put a blow valve with an 1 8 in hole in nozzle on the hose and open it up the pressure gauge on regulator will drop from 140 psi to 100 psi and then maintain pressure at 100. I have a 21 cfm 80 gallon compressor. It wouldn t get above 30 psi meaning you couldn t even use it to put air in your tires. Step by step instructions to repair air compressor with a faulty regulator that does not allow adequate air pressure to come out of air hose.
