Nortek Global Hvac 669761r Biflow Filter Drier 16 Inch

Product Description

The NORTEK GLOBAL HVAC 669761r is a replacement biflow filter drier designed for use in refrigeration and air conditioning systems. Filter driers serve a dual purpose: they remove moisture and contaminants from the refrigerant circuit while also filtering debris that can damage compressors, expansion valves, and other system components. This unit measures 16 inches in length and is finished in black. It is rated for bidirectional refrigerant flow, making it suitable for heat pump applications where refrigerant direction reverses between heating and cooling modes. Installation is typically performed by licensed HVAC technicians during system service or refrigerant circuit repair.

This filter drier is intended for HVAC and refrigeration applications where a biflow-capable desiccant filter is required. Its bidirectional design makes it particularly appropriate for split-system heat pumps and other reversing-cycle equipment. The 16-inch body length provides adequate desiccant capacity for residential and light commercial refrigerant circuits. It is sold as a direct replacement component under the Nortek HVAC parts and accessories line, suitable for use during system commissioning, refrigerant retrofits, or after a compressor burnout event that requires full circuit cleanup.

Key Features

• Biflow design supports bidirectional refrigerant flow for heat pump systems
• 16-inch body length provides substantial desiccant and filtration capacity
• Black finish for field identification and corrosion resistance
• Sold as an OEM-style replacement component through Nortek HVAC parts
• Removes moisture and particulate contamination from the refrigerant circuit

Compatibility

Designed as an OEM-style replacement filter drier for Nortek HVAC room air and refrigeration systems requiring a biflow filter drier. Consult the equipment service manual to confirm fitment before installation.

Installation Notes

Filter drier replacement must be performed by an EPA Section 608 certified HVAC technician, as the work involves handling refrigerants and opening the refrigerant circuit. Recover all refrigerant from the system before cutting or unbrazing the existing drier. Install the replacement drier with refrigerant flow direction observed where applicable, and replace the drier any time the system is opened for service. Evacuate the system to the required micron level before recharging with the specified refrigerant type and charge.
