Parker HN15S-6CW Coalescing Air Filter 0.01 Micron 3/8 Npt

Product Description

The PARKER HN15S-6CW is a coalescing compressed air filter designed to remove oil aerosols, water droplets, and submicron particulates from compressed air lines. Rated at 0.01 micron, it delivers high-efficiency filtration suitable for applications where clean, dry air is critical to downstream equipment performance. The filter handles up to 20 standard cubic feet per minute (SCFM) and connects via 3/8 inch NPT end connections. The bowl and body are constructed from aluminum, keeping weight manageable on both fixed and portable compressed air systems. It is installed by pipefitters, HVAC technicians, and industrial maintenance professionals as part of a point-of-use or inline filtration assembly.

This filter is used in residential, commercial, and light industrial compressed air systems where oil-free, particulate-free air is required. Typical applications include instrument air supply, pneumatic tool protection, spray finishing, and protection of sensitive pneumatic controls. The 3/8 inch NPT port size suits standard small-bore compressed air branch lines. The manual drain allows periodic removal of collected liquid without system shutdown in low-condensate applications. Series H construction from Parker is engineered for reliable inline service in both horizontal and vertical orientations.

Installation Notes

Installation should be performed by a qualified pipefitter or mechanical technician familiar with compressed air system standards. Depressurize and lock out the compressed air supply before installing or servicing the filter. Apply appropriate thread sealant to NPT connections per standard piping practice. Mount the filter with the bowl oriented downward to allow proper condensate collection and manual drain access.
