ALCO ASK-165SVV Filter Drier

ALCO ASK-165SVV suction-line filter-drier is a compact device designed for the suction side of HVAC and refrigeration systems. It uses a solid-core element with an activated carbon blend to trap moisture and acids, helping protect compressors and maintain oil integrity. The unit features dual 5/8-inch SAE ODF connections, matching standard suction-line fittings for easy installation. It is part of ALCO's ASK family of suction-line filter-driers and is compatible with common refrigerants such as R-134a, R-22, and R-404A/R-507A, per ALCO/Emerson catalogs. In operation, it cleans the refrigerant by removing moisture, acids, and particulates as it flows toward the compressor, reducing acid formation and varnish buildup. Used in a wide range of residential and commercial systems, the 165SVV is a mid-sized option in the ASK line designed for reliable suction-line filtration in standard service conditions.
