Screw Air Compressor Repair Kits

A: Piston-type (reciprocating) compressors typically last about 10,000 - 20,000 hours before a rebuild is necessary. On the other hand, a rotary screw compressor will last between 80,000 - 100,000 hours.

A: Change the oil separator every 8,000 hours, including lubricant, to keep your air compressor lubricated and prevent contamination. You'll also want to pay attention to your separator pressure alarm or replace it if the pressure drop through the separator is over 10 psi.

A: Oil flooded screw compressors are used in a wide variety of applications including air compression, gas refrigeration, hydrocarbon processing and power utilization from low-grade heat sources.

A: For dry screw compressors the typical tip speed range for all compressor sizes is between 50 and 150 m/s. In some cases, even lower or higher tip speeds are realized. The rotor diameters are in the range of approximately 100 mm up to > 800 mm.
