Screw Air Compressor Repair Kits

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: Repairing your compressor can be a practical option in the following situations: If it's relatively new and hasn't accumulated many operating hours. If it hasn't been largely replaced by newer technology that offers significant improvements.

A: Mechanical discharge capacity control is realized through a slider valve, which adjusts compressor displacement by shifting the start of the compression process via axial movements of a slider valve. Controlled by solenoid valves, the slider enables smooth capacity regulation over an entire operating range.

A: Screw compressors are generally limited to discharge pressures of around 375 psig (2,585 kPag), depending on the manufacturer, which can restrict their use in applications requiring higher pressures.
