Low Pressure Oil Filters

Maximum Working Pressure - 450 psig


Oil filters should always be used in conjunction with any oil control system. The filter ensures refrigeration oil is clean of any foreign matter that may obstruct float valves in oil regulators and oil separators. Our filters are designed to be a low pressure drop filter, while remaining effective at removing particulate matter. The F3-01 and F3-02 models are designed using XH-9 desiccant for removal of moisture in POE oils and contaminants.
