Hankison HF7-12-3-DPL Filter

The Hankison HF7-12-3-DPL is a professional-grade compressed air filter engineered for high-performance liquid water and oil removal in demanding industrial environments. As a Grade 7 general purpose air line filter, it utilizes a sophisticated two-stage filtration process to ensure downstream equipment longevity. The first stage employs alternating layers of fiber media and a media screen to trap large solid particles, while the second stage uses epoxy-bonded blended fiber media to coalesce aerosols and capture solid particulates down to 1 micron. With a 20 SCFM flow capacity and 3/8" NPT connections, this unit is optimized for point-of-use filtration and protecting refrigerated air dryers.

Built for the rigors of the shop floor, the housing features a piston-type element seal to prevent unfiltered air bypass and corrosion-resistant stainless steel cores for structural integrity. The integrated internal automatic drain (AutoDrain) eliminates manual maintenance by automatically discharging collected condensate, while the differential pressure slide indicator and liquid level indicator allow for real-time monitoring of filter health and performance. This silicone-free assembly operates efficiently at temperatures up to 150°F, ensuring high-efficiency air filtration and a maximum remaining oil content of just 1.0 ppm w/w.

• Efficient Contaminant Removal: Effectively filters solid particles to 1 micron and reduces oil carryover to 1.0 ppm w/w.
• Maintenance-Free Drainage: The automatic drain ensures continuous moisture removal without technician intervention.
• Technical Monitoring: Includes a differential pressure indicator to identify exactly when the E7-12 replacement element requires changing.
• Durable Construction: Seam-welded stainless steel cores and chemically resistant end caps withstand high-pressure pneumatic cycles.
• Low Pressure Drop: Matrix blended fiber media provides a large surface area, maximizing capture rates while minimizing energy loss.

What is the maximum flow rate and pressure for this unit?
The Hankison HF7-12-3-DPL is rated for a flow capacity of 20 SCFM at standard operating pressures, with a maximum housing rating typically up to 250 PSIG.

Which replacement element does this filter use?
This housing is designed to work specifically with the Hankison E7-12 element grade, which is a Grade 7 coalescing filter element.

Is this filter compatible with synthetic compressor lubricants?
Yes, the coated closed-cell foam sleeve and epoxy-bonded media are designed to resist chemical attack from both mineral and synthetic compressor lubricants.
