HONGSEN BFK Series Bi-Flow Refrigeration Filter Driers
Product Description
Product Overview
The HONGSEN BFK Series consists of bi-flow filter driers designed for installation in the liquid lines of refrigeration and air-conditioning systems requiring refrigerant flow in both directions.
The internal filtration system removes moisture and solid contaminants from the refrigerant circuit, helping protect compressors, expansion valves and other sensitive refrigeration components.
BFK filter driers contain a solid core composed of 80% 3A molecular sieve and 20% activated alumina. This combination provides moisture absorption and acid-removal performance for compatible HCFC and HFC refrigeration systems using POE or PAG synthetic lubricants.
SAE flare and copper ODF solder connection versions are available.
