White-rodgers BSS307S Suction Line Filter-drier

Product Description

The WHITE-RODGERS BSS307S is a suction line filter-drier designed to remove moisture, acid, and solid contaminants from refrigerant systems. Installed on the suction line between the evaporator and compressor, it protects the compressor from debris and moisture that can cause premature failure or acid burnout. With a 7/8 inch ODF connection, this filter-drier fits common residential and light commercial refrigerant circuit configurations. Licensed HVAC technicians install this component as part of system cleanup procedures following compressor replacement or contamination events.

This filter-drier is suited for suction line service in split systems and package units where system contamination needs to be addressed. It is typically installed during compressor changeouts or after a burnout to capture residual acid, carbon, and particulate before they reach the new compressor. The 7/8 inch ODF connection size makes it applicable across a range of mid-capacity residential and light commercial systems.

Key Features

• Suction line design rated for low-pressure, vapor-phase refrigerant flow
• 7/8 inch ODF connections for direct brazing into the suction line
• Removes moisture, acid, and particulate contaminants from the refrigerant circuit
• Supports system cleanup applications following compressor burnout or contamination
• OEM-style construction suited for residential and light commercial HVAC service

Compatibility

Designed as an OEM-style replacement suction line filter-drier for residential and light commercial refrigerant systems with 7/8 inch ODF suction line connections.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification. Recover all refrigerant before cutting or brazing into the suction line, and allow the system to reach zero pressure before opening any connections. Braze the filter-drier into the suction line using nitrogen purge to prevent internal oxidation, and replace the filter-drier after the initial cleanup period as outlined by system service procedures. Flow direction must match the arrow marked on the drier body.
