How to Adjust Your Compressor Air Pressure Switch

Have you had air compressor problems ? Do you think it needs to be replaced or maybe it needs an air compressor repair? Air compressors can usually put up 110-120 psi which is necessary when needing to inflate large truck tires Or use air tools. But if you observed that your old air compressor does not seem to get to its usual 120 psi, then no worries because maybe it only needs the air compressor pressure switch to be adjusted.
If you have been monitoring your old compressor because it’s starting to make loud noises and seems to have difficulty reaching its usual pressure, the only way you can help it is by adjusting the compressor pressure switch to a lower level so that it doesn’t need to reach the high psi requirement and make it not work so hard to maintain its pressure.
Air compressors come in 4 different types: reciprocating, centrifugal, rotary-screw, and rotary vane and all of them have mechanical parts that work hard during operation. But just like our cars, as our air compressors get old, their parts also weaken and reduce their capacity to work hard.
So if you hear those loud noises inside your air compressor, don’t worry it’s not about to break in half. It just means that the usual air pressure that it previously reached can hardly be managed and the better way to help your machine is to lower its air capacity by adjusting its air compressor pressure switch to a lower level.
In this video, I’m going to show you how the air compressor pressure switch adjustment is being done. Though I do not recommend air compressor pressure switch adjustment because the consequence to your machine can be unpredictable, my point in this video is you can only do this compressor pressure switch adjustment if your unit is already experiencing difficulties in reaching up to its usual high psi.
I have also taught you here how to deal with compressor pressure switch adjustment by using only a screwdriver and no need for an air expensive compressor repair. What benefits your air compressor can get when lowering the air pressure requirement thru adjustment is, your machine won’t need to work hard and it might prolong your old air compressor life span a bit.
