How To Fix Air Compressor Regulator

The item inside the regulator that keeps the air flow from leaking out is the diaphragm.

How to fix air compressor regulator.

Fix an air compressor regulator for under 10. The air capacity of the compressor depends on the size of the unit and commonly runs between 100 and 200 psi per square inch. When the compressor tank has plenty of air but you only get a short burst of air pressure only momentarily out of air hose and compressor s air hose gauge goes to zero. Been meaning to do this for years but sin.

Connect your tool to the air hose and connect the hose to the air compressor. The regulator has to be readjusted to maintain set pressure even when using very small amount of air. 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. 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.

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. It wouldn t get above 30 psi meaning you couldn t even use it to put air in your tires. Air compressor repair can be simple. Allow the compressor to fill completely.

A friend was going to toss this in the trash because of a bad regulator. Well life happens and i ended up with a new job so this sat for two years. Connect the air compressor to the power and turn it on. 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.
