Refrigerant Filters

Refrigerant Filters are basic components of HVAC systems. They are designed to absorb any excess moisture in the refrigerant and to provide physical filtration while also not impeding the refrigerant’s flow through the system. Moisture can quickly cause damage to various components in the HVAC unit, most notably the compressor.

Refrigerant Filters are usually found in the liquid line and occasionally also in the suction line of the compressor. The suction line is the segment of refrigerant piping leading to the compressor inlet. And the liquid line is the segment following the compressor outlet.

Filters typically include screens which are in place to ensure the desiccant and other particulates remain in the filter drier.
