Carrier p504-h083s Bi-directional Filter Drier

Product Description

The CARRIER p504-h083s is a bi-directional filter drier engineered to remove moisture and contaminants from refrigerant circuits in HVAC systems. Operating in either flow direction, this desiccant-type component protects compressors, expansion devices, and heat exchanger surfaces from acid, particulates, and water intrusion that cause premature system failure. The bi-directional design makes it well suited for heat pump applications where refrigerant reverses flow between heating and cooling cycles. Licensed HVAC technicians and refrigeration mechanics are the primary installers of this component during system service or refrigerant circuit repairs.

The p504-h083s is intended for use in residential and light commercial heat pump and air conditioning systems that require filter drier protection in a reversible-flow refrigerant circuit. Its OEM-style construction is matched to Carrier system specifications, making it a direct-fit option during refrigerant circuit service, compressor replacement, or system dehydration and recharge procedures. Consult system documentation to confirm line set sizing and connection compatibility before installation.

Key Features

• Bi-directional flow configuration for use in heat pump and reversible-cycle refrigerant systems
• Removes moisture, acid, and particulate contaminants from the refrigerant circuit
• OEM replacement part engineered to Carrier system specifications
• Compact form factor: 9 inches length, 7.5 inches width, 7 inches height
• Protects downstream components including compressors and expansion devices

Compatibility

Designed as an OEM-style replacement filter drier for Carrier residential and light commercial heat pump and air conditioning refrigerant systems requiring a bi-directional filter drier.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before opening the refrigerant circuit. After installing the filter drier, evacuate the system to the required micron level before recharging with the specified refrigerant type and quantity. Replace the filter drier any time the refrigerant circuit is opened, and never reuse a previously installed drier.
