Filter driers are essential maintenance components in HVAC systems, protecting against moisture-related damage that can cause acid formation and internal corrosion. The molecular sieve core adsorbs and retains moisture deep within the desiccant material while filtering out solid contaminants. This dual-action protection ensures optimal system performance and extends equipment life. Commonly used in Marvair COMPAC air conditioner models including AVP72AC and AVPA72AC series units.

Note: This is a unidirectional filter drier designed for liquid line installation only. Refrigerant must flow in the correct direction as indicated by the arrow on the filter body.
