Parker 164S Liquid Line Filter Dryer

The Parker 164S liquid line filter dryer is built for HVAC technicians servicing residential and light-commercial air-conditioning and refrigeration circuits. It removes moisture, acid and solid contaminants from the refrigerant stream to protect compressors and metering devices.

R-22 7 ton and R-410A 5 ton capacity limits

The unit is rated for 7 tons with R-22 and 5 tons with R-410A, so systems above those capacities need a larger filter dryer. It is approved for all CFC, HCFC and HFC refrigerants and uses a 75/25 desiccant blend optimised for common refrigerant and oil combinations.

Solder connections with 5-1/16 inch cut-out

Installation requires brazing the 1/2 inch solder fittings, leaving a 5-1/16 inch cut-out in the liquid line. Common issues are overheating the shell during brazing, which can damage the desiccant core, and failing to purge with nitrogen, which introduces oxidation into the system.

Questions about this item

Should I choose the 75/25 desiccant blend or a different ratio?

The 164S uses a fixed 75/25 desiccant blend optimised for moisture and acid removal across all CFC, HCFC and HFC refrigerants.

What does the 7 ton R-22 rating mean once the dryer is installed?

It indicates the maximum R-22 system capacity the dryer can protect while maintaining proper flow and filtration.

How does the solder connection affect the pressure rating?

The solder connection creates a permanent, leak-free joint suitable for the high pressures found in R-410A systems up to 5 ton capacity.
