Hankison HF512-3DPL Oil Removal Filter

The Hankison HF512-3DPL is a professional-grade high efficiency oil removal filter designed to maintain air quality in critical pneumatic systems. Engineered for a 20 SCFM flow rate at 100 PSI, this Grade 5 coalescing filter effectively targets fine water and oil aerosols, removing solid particulates down to 0.01 microns. The 3/8" NPT connection ensures a secure fit for standard shop air and instrument air lines, while the dual-stage filtration process—utilizing a coated, closed-cell foam sleeve and matrix-blended fiber media—achieves a maximum remaining oil content of just 0.008 ppm w/w. This model serves as the direct replacement for HF5-12-3-DPL and HKN-HF512-3DPL. Integrated maintenance features like the internal automatic drain and differential pressure slide indicator allow technicians to monitor performance and manage condensate without manual intervention, preventing re-entrainment of liquids and protecting downstream equipment from oil contamination.

• Sub-Micron Coalescing: Grade 5 element removes 99.99+% of oil aerosols and particles to 0.01 microns.
• Integrated Monitoring: Features a differential pressure slide indicator and liquid level indicator for real-time status updates.
• Efficient Drainage: The internal automatic float drain removes collected liquids under pressure to prevent carryover.
• Standardized Fit: 3/8" NPT ports simplify installation into existing compressed air systems.
• Durable Construction: Stainless steel inner and outer cores provide structural integrity against pressure surges.

What is the maximum operating pressure for the HF512-3DPL?
While optimized for 20 SCFM at 100 PSI, the housing is typically rated for a maximum working pressure of 250 PSIG at 150°F.

When should I replace the Grade 5 filter element?
Technicians should swap the element when the differential pressure slide indicator shows a 10 PSI drop or annually, whichever occurs first, to maintain ISO air quality standards.

Will this filter remove oil vapor?
No, Grade 5 is a coalescing filter for aerosols. For oil vapor removal (odors), a Grade 1 activated carbon filter must be installed downstream.
