Frequently Asked Questions

 In order to assist you with some of the more common issues that can arise with your air compressor and compressed air system, we have compiled a list of the top issues and their remedies.


How do I get rid of the water in my lines?
Water gets into the compressed air stream by being drawn into the compressor from ambient air. The warmer the ambient inlet air is, the higher the moisture content of the compressed air may be. You can add filters at the point of air consumption to catch any liquid water as an inexpensive solution but you will still have moisture. In order to totally remove the water in your compressed air, you must dry it.  You can do this by using either a refrigerated OR regenerative dessicant compressed air dryer. 


What causes a rotary compressor to shut down from high temperature?
Several things can cause a rotary compressor to shut down.  A low oil level, a dirty or blocked radiator, bad thermostatic element, bad radiator fan or a bad high temperature switch.  The majority of the time, it is caused by either a low oil level or a dirty radiator.  Resolving one of these two common situations usually cures a high temperature shut down problem.


What causes the compressor to hum when trying to start?
This condition may be caused by a tight or seized pump or motor but is usually caused by a bad fuse, burnt wire/connection or a bad contactor.  If you are not familiar with electrical troubleshooting, feel free to call us to solve this problem for you.


What causes a piston compressor to continually bleed after shutdown?
Piston compressors deliver their air from the pump outlet, through a discharge line and check valve(one way valve) to the tank/receiver.  When the unit stops, the compressor relieves the air pressure above the check valve to atmosphere to make starting easier.  If the unit continually bleeds after shutdown, the check valve is bad, allowing air to come up from the tank and it must be replaced.
