The Importance of Your Air Compressor Pressure Switch Although you may not think of it often, your air compressor pressure switch is an integral part of your entire compressor system. It may be small, but this little gauge keeps your machine from running non-stop, eventually burning out the motor. The air compressor pressure switch monitors the pressure in the air receiver tank. When the pressure in the tank gets to the proper level, the switch tells the motor to turn off. Alternately, this switch stimulates the motor to turn on if the pressure level gets too low. By ensuring that your air compressor doesn’t exceed the maximum allowed pressure in the air receiver tank, your air compressor pressure switch helps you avoid potentially catastrophic damages, including having your motor burn out or even a rupture in your system. The air compressor pressure switch also saves you energy costs. Rather than have your compressor motor run full-time, this switch allows you to use the motor only when necessary, cutting down on unnecessary energy usage and therefore costs. If you notice your air compressor motor running excessively or simply want a check-up for your air compressor pressure switch to avoid expensive repairs, call or e-mail Compressed Air Systems today.
