A rotary screw compressor is a machine that applies positive-displacement technology to compress air. It functions by spinning two screws with their thread mesh in opposite directions. This draws air into the containment unit, before it is compressed and eventually forced out through a release valve.

Applications such as air conditioning, refrigeration, industrial manufacturing, and powering air tools – like impact wrenches and air ratchets – can all be satisfied with the use of rotary screw compressors.

An array of models and sizes of rotary screw compressors exist, the most popular being the oil-injected variety. Oil is used to keep the screws and seals lubricated, though pricier and more labor-intensive oil-free models are also available.

To begin, make sure that the rotary screw compressor is well-lubricated. Verify the oil level and top off as needed. Continuing on, link up the inlet and outlet hoses to the compressor. Lastly, activate the compressor and give it some time to generate pressure.

Once the desired pressure measure has been accomplished, the compressor requires to be stopped. Following from this, it is essential to unplug the hoses and switch off the unit.
