Parker HN2S-AUN Adsorber Compressed Air Filter 25 Scfm

Product Description

The PARKER HN2S-AUN is an adsorber-type compressed air filter designed to remove oil vapor, hydrocarbons, and odors from compressed air lines. It belongs to Parker's Series H filter lineup and is built with an aluminum bowl and aluminum body for corrosion resistance and durability in industrial and trade environments. The filter handles up to 25 Standard Cubic Feet Per Minute (SCFM) and connects via 1/2 inch NPT fittings. Manual drain operation keeps the design simple and reliable. HVAC technicians, plumbers, and industrial maintenance professionals install this filter where clean, dry compressed air is required for tools, instrumentation, or system processes.

The HN2S-AUN is suited for use in compressed air systems where air purity is critical. Typical applications include point-of-use filtration for pneumatic tools, spray finishing equipment, instrumentation air lines, and any system where residual oil vapor or hydrocarbon contamination must be eliminated. The manual drain design is appropriate for installations where periodic maintenance is part of a regular service schedule.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system safety procedures. Depressurize and lock out the compressed air supply before installing or servicing this filter. Ensure NPT threads are properly sealed with thread tape or a compatible pipe sealant rated for compressed air service. Drain the bowl manually at regular intervals as part of a preventive maintenance schedule to prevent condensate buildup.
