Copeland 043732 BFK165 Bi-Directional Liquid Line Filter Drier

Description

Copeland BFK165 Bi-Directional Liquid Line Filter Drier

The Copeland 043732 (Model BFK165) is a high-performance bi-directional liquid line filter drier engineered to protect refrigeration and air conditioning systems from moisture, acid, and particulate contamination. Its bi-directional flow design makes it an ideal solution for heat pump applications and systems where refrigerant flow may reverse direction, eliminating the need to orient the drier during installation.

Key Features

• Bi-directional flow design — suitable for heat pump and reversing-cycle systems
• 5/8″ flare connections for easy, leak-free installation
• 16 cubic inch internal volume for high desiccant capacity
• 40 micron filtration rating removes particulates and debris from the refrigerant circuit
• 680 PSI maximum working pressure for compatibility with a wide range of refrigerants and system pressures
• Effectively removes moisture, acid, and contaminants to protect compressors and system components
• Durable construction built to Copeland’s exacting quality standards
