Sporlan 400437 C-084-S Filter Drier

The Sporlan 400437 C-084-S Filter Drier is a high-performance liquid line filter drier engineered for HVACR systems requiring professional-grade contaminant control. Featuring a 1/2 ODF solder connection and an 8 cubic inch desiccant volume, this Catch-All series unit utilizes a molded porous core to capture moisture, acid, and solid debris. It is rated for 650 psig maximum working pressure, making it fully compatible with R-410A, R-22, and other high-pressure refrigerants. For technicians performing field service or OEM replacements, the C-084-S provides low pressure drop and high filtration capacity, effectively protecting the TXV and compressor from sludge and wax. Its solid copper fittings ensure reliable brazing in the field while maintaining the integrity of the refrigerant circuit. Use this sealed model to ensure long-term system stability in residential or commercial refrigeration applications.

• High-Capacity Filtration: The 8 cubic inch molded core captures moisture and organic acids that lead to compressor failure.
• Superior Construction: Features 1/2-inch ODF solid copper connections for leak-proof solder joints.
• Contaminant Control: Effectively removes solder particles, scale, and carbon to protect sensitive metered orifices.
• Pressure Rated: UL listed for 650 psi, suitable for R-410A and sub-critical CO2 applications.
• Universal Application: Compatible with various oils and widely used refrigerants, including HFC, HCFC, and HFO.

Is the Sporlan C-084-S suitable for heat pump applications?
This specific model is a standard liquid line drier designed for unidirectional flow. For heat pump systems requiring bidirectional filtration, a dedicated reversible drier should be used.

Can this filter drier be used on the suction line?
No, the 400437 is specifically engineered for liquid line installation. Installing this unit in the suction line will result in excessive pressure drop and may damage the system.

What is the difference between ODF and SAE flare connections?
This model features ODF solder (sweat) connections. If your system requires threaded flare nut connections, look for the SAE flare equivalent in the Sporlan catalog.
