Product details
Oil Separator 5/8″ 16mm ODS OS540/5 Castel
The Castel OS540/5 oil separator is installed in the compressor discharge line to remove oil carried by refrigerant gas. After separation, the oil is directed back to the compressor crankcase, maintaining correct lubrication and reducing mechanical wear.
In refrigeration systems, oil circulation through the piping network can reduce heat transfer efficiency and affect system performance. This oil separator helps maintain proper oil balance and stable cooling capacity.
With its 5/8″ 16mm ODS connection, it is suitable for small to medium refrigeration and HVAC installations requiring dependable oil management.
