HONGSEN DFS Series SAE Flare Liquid Line Filter Driers
Product Description
Product Overview
HONGSEN DFS Series SAE flare filter driers are designed for installation in the liquid line of refrigeration and air-conditioning systems. They absorb moisture from the refrigerant and capture solid contaminants, helping protect compressors, expansion valves and other system components.
The filter drier uses a 100% 3A molecular-sieve solid cartridge together with a 100 μm filter pad. It is suitable for HCFC and HFC refrigeration systems and compatible with systems using POE or PAG oil.
The threaded SAE flare connections allow convenient installation and replacement without brazing.
