CompAir is one of the most widely deployed industrial rotary screw compressor brands in the world. The L and D series models, covering the L02–L250 output range, are preferred in demanding continuous-duty applications across food production, pharmaceuticals, automotive, and general manufacturing. The Delcos control system digitally manages load/unload cycling, fault codes, and service scheduling.
The leading causes of efficiency loss in rotary screw compressors are blocked air filters, saturated oil separator elements, a failing minimum pressure valve, and worn airend rotors. At HAVKOM Engineering, we carry out all CompAir service operations including Delcos fault code reading and reset, while keeping maintenance costs reasonable with OEM-compatible replacement parts.
All service interventions are documented in a digital service report with on-site measurements (discharge pressure, operating temperature, load ratio). With scheduled preventative maintenance and precision airend overhaul capabilities, we minimise production downtime.
