Hankison E9-12-02 Filter Cartridge

The Hankison E9-12-02 Filter Cartridge is a professional-grade Grade 9 separator/filter element designed for high-demand industrial compressed air systems. Built to replace OEM part numbers 07.4441-01 and HKN-E9-12-02, this cartridge features a robust two-stage filtration design. The first stage utilizes two stainless steel orifice tubes to achieve 10-micron mechanical separation, while the second stage employs in-depth fiber media to capture solid and liquid particles down to 3 microns. This configuration ensures a maximum remaining oil content of 5 ppm w/w, meeting CAGI standard ADF400. The E9-12-02 is engineered with corrosion-resistant inner and outer cores, making it a reliable solution for bulk liquid removal upstream of refrigerated air dryers. For peak distribution efficiency and system reliability, technicians should replace this element when the pressure differential exceeds 10 psi or during annual maintenance cycles. This replacement filter element maintains strict air quality standards while preventing downstream contamination in pneumatic circuits.

Key Benefits:

• Dual-stage filtration provides 3-micron particulate removal and bulk liquid separation in a single housing.
• Features high-strength stainless steel orifice tubes for superior structural integrity under pressure.
• Directly replaces Hankison E9-12-02 and 07.4441-01 for seamless integration into existing filter housings.
• Reduces downstream oil carryover to 5 ppm, protecting sensitive pneumatic tools and components.
• Constructed with a coated closed-cell foam sleeve that functions as a pre-filter and flow dispenser.

Common Questions:

When should the E9-12-02 filter element be replaced?
For optimal performance, the cartridge should be swapped out when the pressure drop across the filter reaches 10 psi (0.7 kgf/cm2) or at least once per year to prevent contamination carryover.

Is this cartridge compatible with ultra-high efficiency oil removal?
The Grade 9 (E9) is specifically a separator and general-purpose particulate filter. If your application requires sub-micron oil removal (0.01 ppm), a Grade 5 or Grade 3 coalescer should be installed downstream of this unit.

Will this filter remove water vapor?
This cartridge is designed for bulk liquid water and oil removal. To eliminate water vapor, this filter must be used in conjunction with a refrigerated or desiccant air dryer.
