Product details
Oil Separator 1.3/8″ 35mm ODS OS540/11 Castel
The Castel OS540/11 oil separator is installed in the compressor discharge line to remove oil carried by refrigerant gas. Once separated, the oil is returned to the compressor crankcase, maintaining proper lubrication and preventing premature wear.
In medium to large-capacity systems, oil circulation through the piping network can reduce cooling efficiency and cause lubrication issues. This oil separator minimizes those risks and supports stable operation in commercial and industrial HVAC installations.
With its 35mm ODS connection, it is suitable for larger refrigeration systems requiring dependable oil management and long-term performance.
