Diversi-Tech NCHBF-084S Solid Core Bi-Flow Filter Drier 1/2" ODF Sweat

The Diversi-Tech NCHBF-084S is a solid core bi-flow (bidirectional) filter drier with 1/2" ODF sweat (solder) connections, engineered for installation on the liquid line of reversible refrigeration and heat pump systems. Its bidirectional design allows refrigerant to flow efficiently in both the heating and cooling directions without the need for external check valves, making it the ideal choice for heat pump applications.

The solid core construction utilizes a blend of molecular sieve and activated alumina media to deliver superior moisture adsorption, acid neutralization, and particulate filtration — protecting system components and extending equipment life. Compatible with a wide range of modern refrigerants including R-410A, R-22, R-134a, R-407C, R-404A/R-507, R-32, and R-454B.

Key Features:

• Solid core bi-flow (bidirectional) design for reversible refrigeration and heat pump systems
• 1/2" ODF (sweat/solder) inlet and outlet connections
• Removes moisture, acid, and system contaminants in both flow directions
• Molecular sieve and activated alumina core media for high-capacity drying and acid removal
• Compatible with R-410A, R-22, R-134a, R-407C, R-32, R-454B, and other common refrigerants
• Powder-coated steel shell with copper ODF sweat connections
• 8 cubic inch desiccant capacity (08 series)

The NCHBF-084S is part of the NDL/Diversi-Tech NCHBF solid core bi-flow filter drier series, available in a range of connection sizes and desiccant capacities for residential and commercial HVAC-R applications.
