Air Compressor Pressure Switch Adjustment

Pressure switch with low air pressure.

Air compressor pressure switch adjustment.

The air compressor regulator controls how much air flows from your compressor to your air tools. My compressor holds 120 lbs. It also controls the compressor cut out pressure level too. When it drops to 90 it kicks back on.

Observe the compressor s pressure gauge while it is running and take note of the pressure reading when it stops running. However the compressor has its own internal pressure switch settings that control the tank pressure by setting the pressure point at which the motor should turn on and when it should turn off typically these cut in and cut out settings don t need to. In this guide you can learn about air compressor pressure switch adjustment in the easiest way possible. Plug in the air compressor and turn the on off switch to the on or automatic position.

Air compressors are on demand tools. Shut off the power to the compressor. The air compressor will start immediately. Adjustment will vary depending on t.

To make a compressor pressure switch adjustment you will need to remove the cover from your pressure switch. When you turn the screw clockwise the spring is compressed more. If the pressure switch comes with a fixed differential it is usually in the range of 0 8 1 bar and should normally be stated somewhere on the housing or. It has a pressure gauge for measuring output.

Adjust my pressure with cut in. The adjustment is done by compressing the spring using a long screw. Depending on the make and model of pressure switch one can adjust only the pressure setting with a fixed differential or one can adjust both the pressure setting and the differential. I run a mobile service.

However if you learn to do it by yourself you will save lots of money. This is the cut out pressure setting. How do i adjust ed the thing that controls the air compressor cut in pressure is the pressure switch. It does that by letting you adjust the cut in and cut out pressure.

An air compressor will start kick on when the pressure psi in the air tank drops to a pre set psi example 90 psi. You may still need to try to adjust the setting on a new pressure switch to match the old pressure switch settings. Let the air compressor run until it shuts off. A pressure switch of an air compressor helps to start and stop the compressor automatically.

The air compressor will continue to run until the pressure psi in the air tank reaches the max psi that is pre set and kick off shut off example max 120 psi. Adjusting air compressor pressure switch can be difficult and taxing for many people.

This video gives an explanation on how to adjust an air compressor pressure switch as well as basic wiring instructions.
