There are times when screw compressors have to operate at high ambient temperatures, which raises questions about the impact on this vital machine.

Although all air compressors compress air, there are differences in the way centrifuges, oil rotating vanes, oil-free rotary vanes, pistons, and rollers compress air. You can also check for the turn air converters through various online sites.

Rotary Screw Air Compressors

The rotating screw that compresses the air is in the center of the figure. In the case of an oil-filled air compressor, the bag with the rotating screw is filled with oil and the oil acts as a seal that supports the compression and suction of heat from the compressed air. 

With an oil-free rotary screw compressor, the bag is oil-free and approximately hotter than an oil-filled air compressor. For both air compressors, an increase in ambient temperature increases the operating temperature of the air compressor.

The potential impact on a screw compressor operating beyond its design point is that it can shorten the life of the motor or cause it to fail. Working with an electric motor on top of its thermal structure is likely to result in winding and/or bearing failure. 

A good analogy to painting on an air compressor is the buildup of plaque on your teeth. Paint or dirt/particles collect in the air compressor. Non-genuine oil will cause hole accumulation, the backlash of the rotor/stator, etc. 

This can shorten the life of the grille and lead to premature restoration or replacement. This may mean long, unplanned downtime with unexpected maintenance costs.
