Parker HN3S-6CY Coalescing Air Filter 0.01 Micron 3/4 Npt

Product Description

The PARKER HN3S-6CY is a coalescing compressed air filter designed to remove oil aerosols, water mist, and submicron particulates from compressed air lines. Rated at 0.01 micron, it delivers high-efficiency filtration suitable for critical downstream equipment, instrumentation, and pneumatic tooling that cannot tolerate contamination. With a rated flow capacity of 80 SCFM and a 3/4 inch NPT port, it handles moderate to high-flow industrial and commercial compressed air systems. The automatic drain eliminates manual service intervals and reduces the risk of liquid carryover. The aluminum bowl and body construction keeps weight low while resisting corrosion from condensate and oil.

This filter is used in industrial facilities, manufacturing plants, HVAC control air systems, and compressed air distribution networks where clean, dry air is required. It is well suited for protecting pneumatic cylinders, solenoid valves, air-operated tools, and process instrumentation. The 3/4 inch NPT end connections allow direct inline installation into standard compressed air piping systems. Licensed industrial mechanics, pipefitters, and HVAC/R technicians routinely install this type of filtration equipment as part of air treatment assemblies alongside regulators and lubricators.

Key Features

• 0.01 micron coalescing filtration removes oil aerosols and fine water mist from compressed air
• 80 SCFM rated flow capacity for moderate to high-demand air systems
• 3/4 inch NPT end connections for standard inline pipe installation
• Automatic drain eliminates manual draining and reduces liquid carryover risk
• Aluminum bowl and body construction for corrosion resistance and reduced weight
• Parker Series H design for consistent OEM-level performance

Compatibility

Designed as an OEM-style inline coalescing filter for compressed air systems with 3/4 inch NPT piping connections and flow requirements up to 80 SCFM.

Installation Notes

Installation should be performed by a qualified pipefitter, industrial mechanic, or HVAC/R technician. Depressurize and lock out the compressed air system fully before installing or servicing this filter. Mount the unit vertically with the bowl facing downward to allow proper condensate drainage and ensure the automatic drain functions correctly. Follow all applicable piping codes and the system manufacturer guidelines for air treatment component placement and spacing.
