Hankison HF7-20-4-DP Air Filter

The Hankison HF7-20-4-DP is a Grade 7 General Purpose Air Line Filter engineered for heavy-duty compressed air filtration in industrial and HVACR environments. Designed to protect downstream pneumatic components, this 1/2" NPT air filter utilizes a sophisticated two-stage filtration process to eliminate liquid water, oil aerosols, and solid particulates down to 1 micron. Its all-aluminum housing features a pressure drop indicator (DP) to monitor element loading, ensuring your system maintains peak scfm output without excessive energy loss. The integrated automatic drain (AutoDrain) effectively manages condensate removal, preventing liquid carryover that can lead to tool corrosion or process contamination. With a 60 SCFM capacity at 100 PSIG, this Hankison HF Series filter is the standard for reliable inline air filtration.

• Superior Protection: Provides high-efficiency removal of liquid water and oil with a maximum remaining oil content of 1.0 ppm w/w.
• Minimal Pressure Drop: The matrix blended fiber media and large flow paths reduce operating costs by minimizing resistance.
• Automated Maintenance: Standard internal automatic drain ensures continuous moisture evacuation without manual intervention.
• Durable Construction: Features corrosion-resistant cores and epoxy-coated housings for longevity in harsh mechanical rooms.
• Easy Serviceability: Employs push-on elements and a piston-type seal to prevent unfiltered air bypass during replacement.

What is the micron rating for the Grade 7 element?
The Grade 7 filter is rated for 1-micron particulate removal, making it ideal for protecting air motors, cylinders, and valves.

When should I replace the filter element?
Technicians should replace the element when the differential pressure indicator shows 10 psi drop or annually to maintain air quality standards.

Can this filter handle high-temperature compressed air?
The HF7 series is designed to withstand inlet temperatures up to 150°F (66°C), suitable for most standard compressor discharges.
