Parker HN4L-6CY Compressed Air Filter 140 Scfm 1 in Npt

Product Description

The PARKER HN4L-6CY is a compressed air filter designed to remove sub-micron particulates and contaminants from compressed air lines in industrial and mechanical systems. Rated at a 0.01 micron filtration level, it delivers clean, dry air downstream of compressors and dryers where contamination control is critical. The unit flows up to 140 standard cubic feet per minute (SCFM) through a 1-inch NPT port, making it suitable for moderate to high-demand pneumatic circuits. An automatic drain eliminates the need for manual bowl draining during service intervals. The aluminum bowl construction keeps weight low while maintaining structural integrity under typical line pressures. Licensed mechanical and industrial technicians install this filter as part of compressed air treatment assemblies.

This filter is suited for use in industrial facilities, manufacturing plants, HVAC mechanical rooms, and process air systems where downstream air quality directly affects equipment performance and tool life. It fits into compressed air treatment trains alongside regulators and lubricators. The 1-inch NPT port connects directly to standard threaded iron or steel pipe and most pneumatic fittings of the same thread standard. The 140 SCFM flow rating accommodates multi-tool or multi-actuator circuits typical in light to mid-scale industrial settings.

Key Features

• 0.01 micron filtration rating removes fine aerosols and particulates from compressed air
• 140 SCFM flow capacity supports moderate to high-demand pneumatic systems
• Automatic drain removes accumulated condensate without manual intervention
• 1-inch NPT port threads directly into standard compressed air piping
• Aluminum bowl construction reduces overall assembly weight
• 17.64 inch overall height and 4.65 inch width for compact inline installation

Compatibility

Designed as an OEM-style inline compressed air filter for pneumatic systems with 1-inch NPT threaded connections and flow requirements up to 140 SCFM.

Installation Notes

Installation is typically performed by licensed industrial mechanics or pipefitters. Depressurize and lock out the compressed air system completely before removing any existing filter or installing a new one. Use thread sealant tape or compound rated for compressed air service on all NPT connections and confirm no leaks before returning the system to operating pressure. Follow applicable OSHA and local codes governing compressed air system maintenance and pressure vessel handling.
