Ndl Industries NCH-307S Liquid Line Filter Drier 7/8 Inch

Product Description

The NDL INDUSTRIES NCH-307S is a liquid line filter drier designed for use in refrigeration and air conditioning systems. It filters moisture, acid, and particulates from the refrigerant circuit, protecting compressors and metering devices from contamination. The NCH-307S uses a 7/8 inch sweat connection for a brazed-in-line installation. Licensed HVAC technicians install this component during new system startup, refrigerant circuit repairs, or any time the system has been open to atmosphere. Keeping the liquid line free of debris and moisture is a standard requirement for maintaining system efficiency and longevity.

The NCH-307S is suited for residential and light commercial split systems, heat pumps, and refrigeration equipment where a liquid line filter drier with a 7/8 inch sweat connection is required. It is installed in the liquid line between the condenser and the metering device. This size is commonly found on mid-to-larger capacity systems where larger-diameter copper line sets are used.

Key Features

• 7/8 inch sweat connection for brazed installation into copper liquid lines
• Liquid line configuration removes moisture, acid, and solid contaminants from refrigerant flow
• Designed for installation between the condenser outlet and the metering device
• Supports system protection after repairs that expose the refrigerant circuit to air

Compatibility

Designed as an OEM-style replacement or new-installation filter drier for refrigeration and air conditioning systems requiring a 7/8 inch sweat liquid line filter drier.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification. Recover all refrigerant before opening the system and allow the line to depressurize fully before cutting or unsoldering. Use dry nitrogen purge during brazing to prevent oxidation scale inside the drier and refrigerant circuit. Replace the filter drier any time the system has been opened, after a compressor burnout, or when moisture or acid contamination is suspected.
