Parker HN1S-6CW Coalescing Air Filter 0.01 Micron 1/4 Npt

Product Description

The PARKER HN1S-6CW is a coalescing compressed air filter designed to remove oil aerosols, fine particulates, and water droplets from compressed air lines. Rated at 0.01 microns, it delivers high-efficiency filtration suitable for applications requiring clean, dry downstream air. The filter handles up to 15 standard cubic feet per minute (SCFM) and connects via 1/4 in NPT end connections. The bowl and body are constructed from aluminum. Manual drain allows the technician to purge collected liquids during scheduled maintenance. This filter is installed by licensed plumbers, pipefitters, and industrial maintenance technicians working on compressed air distribution systems.

The HN1S-6CW belongs to the Parker H Series and is well suited for light industrial and commercial compressed air systems where oil-free air quality is required. Typical installations include tool supply lines, pneumatic control systems, spray finishing equipment, and instrument air headers. The 1/4 in NPT port size makes it appropriate for smaller branch lines and point-of-use applications rather than large main headers. Manual drain operation keeps the design straightforward for facilities with regular maintenance schedules.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or industrial maintenance technician familiar with compressed air system work. Depressurize and lock out the compressed air supply before removing or installing any filter component. Apply thread sealant approved for compressed air service to NPT connections and torque fittings per the system piping specifications. Orient the filter bowl downward as intended for proper liquid collection and manual drain function.
