Lennox 69018 Filter Drier

The Lennox 69018 Filter Drier is a critical liquid line filter drier designed for high-efficiency moisture and acid removal in residential and light commercial HVACR systems. Featuring a 3/8" sweat (ODF solder) connection and a 5 cubic inch desiccant volume, this OEM component is engineered to protect the compressor and expansion valves by trapping contaminants as small as 20 microns. With a 680 PSI max pressure rating, it is fully compatible with modern high-pressure refrigerants, including R-410A and R-22. As a veteran-preferred HVAC replacement part, the 69018 ensures system dehydration and prevents the formation of harmful acids that lead to motor burnout. Its compact solid core design allows for seamless integration into Lennox and Allied units, maintaining the peak performance of the refrigerant circuit. Contractors rely on the 69018 liquid line drier to maintain HVAC system filtration integrity during routine maintenance or after a compressor burnout to ensure long-term reliability.

What is the micron rating for the Lennox 69018?
This drier provides fine filtration down to 20 microns, ensuring that even microscopic metallic shavings and slag are removed from the system.

Is the 69018 compatible with R-410A systems?
Yes, the 69018 filter drier is rated for a 680 PSI maximum pressure, specifically designed to handle the higher operating pressures of R-410A refrigerants.

Can this be used on suction lines?
No, this is specifically a liquid line filter drier. For suction line protection after a burnout, a dedicated suction line drier with pressure taps is required.
