All openings in the completed compressor package are plugged and the unit is pressurized with nitrogen to 350 psig.
[pdf] The principle of rotary screw air compression is really no different than reciprocating (piston) compression. Both are positive displacement machines that take in a fixed volume of air at atmospheric press.
[pdf] If your compressor is experiencing loading or unloading issues, check the electrical components, such as the solenoid valves, and inspect mechanical components like the air filter, intake valve, and pressure switch.
