Parker 304S liquid-line filter dryer
The Parker 304S is a liquid-line filter dryer built for air-conditioning and refrigeration systems. It uses a 100-per-cent molecular-sieve core to remove moisture and solid contaminants from the refrigerant circuit. The body is constructed from 316 stainless steel for corrosion resistance. It is rated for 10 ton capacity with R-22 and R-410A refrigerants.
Solder connections simplify installation
The unit has 1/2-inch solder connections and an overall length of 9 15/16 inches with an 8-inch cut-out length. A technician brazes the fittings directly into the copper line set during assembly or service. Proper nitrogen purge while brazing prevents oxide scale from entering the system. The stainless shell tolerates high pressures common in R-410A applications.
Suits residential and light-commercial AC
Contractors servicing split systems or packaged units up to 10 tons will find the capacity match convenient. The filter dryer handles all CFC, HCFC and HFC refrigerants encountered in that range. Systems requiring larger tonnage or flare-type connections need a different model. Installers without brazing equipment should consider alternative connection styles.

Questions about this item
How can I confirm the 304S filter dryer is working correctly after installation?
Check that system pressures match the 10 ton R-22 and R-410A capacity ratings and verify no moisture indicators show contamination.
What comes with the 304S unit and what must I source separately?
The 304S filter dryer with 1/2 inch solder connections is supplied; solder, flux and refrigerant for the 10 ton system are not included.
Which capacity version of the 304S should I choose for my application?
This 304S model is rated 10 ton for both R-22 and R-410A; select it when your liquid line requires that capacity.
