HVAC Control for Refrigerant Systems
The Parker 307S is a liquid line filter dryer built for HVAC and refrigeration circuits. It handles R-22 at a 10 ton capacity and R-410A at a 12 13/64 ton rating. The unit uses a 100 percent molecular sieve core to remove moisture and contaminants. It is not for installers who need a replaceable core shell or a suction line filter.
Sustained Contaminant Removal
The steel body contains a solid molecular sieve block that maintains drying performance during continuous system operation. Unlike loose-fill designs that can channel, the fixed core structure ensures consistent refrigerant contact over the full service life. It suits all CFC, HCFC and HFC refrigerants without degradation. The fixed capacity means it cannot be recharged or cleaned once saturated.
Solder Connection Installation
The 7/8 inch solder connections require standard brazing practice with a nitrogen purge to prevent internal oxidation. The cut-out length of 7 3/4 inches sets the exact piping gap needed for a proper fit. Overheating the body during brazing can damage the internal sieve material. No flare or threaded adapters are included for alternative connection types.

Questions about this item
How much heat does the Parker 307S filter dryer generate during continuous system operation?
The Parker 307S is a passive liquid-line filter dryer with no moving parts, so it produces no measurable heat of its own while the system runs all day.
What refrigerant piping and tools must I already have to install this 7/8-inch solder connection filter dryer?
You need copper tubing sized for a 7/8-inch solder joint, a suitable torch, brazing alloy, flux, and a nitrogen purge setup to keep the 100 percent molecular sieve clean during installation.
Will the Parker 307S work in an older R-22 system rated at 10 tons without changing any other components?
Yes, the 307S is rated for 10 tons with R-22 and uses a standard 7/8-inch solder connection, so it fits existing R-22 liquid lines of that size without further modification.
