Product details
Oil Separator 7/8″ ODS OS540/7 Castel
The Castel OS540/7 oil separator is installed in the compressor discharge line to remove oil carried by high-pressure refrigerant gas. Once separated, the oil is returned to the compressor crankcase to maintain proper lubrication.
Without effective oil separation, oil can circulate through the system, reducing heat transfer efficiency and increasing the risk of compressor wear. This oil separator helps maintain balanced operation and protects critical components.
With its 7/8″ ODS connection, it is suitable for medium-capacity refrigeration and HVAC systems requiring dependable oil management.
