Hankison E3-16-03 Filter

The Hankison E3-16-03 Filter is a mission-critical ultra high-efficiency oil removal filter designed for the HF Series housing. As a Grade 3 element, it serves as the primary defense in compressed air systems where high-purity air is non-negotiable. This coalescing filter element is engineered to capture solid particles to 0.01 micron and achieve a maximum remaining oil content of 0.0008 ppm w/w. Built with corrosion-resistant stainless steel cores, the E3-16-03 ensures structural integrity under high-pressure differentials, preventing element collapse during peak demand. The multi-stage filtration process utilizes a matrix blended fiber media and a coated, closed-cell foam sleeve that acts as a pre-filter and flow dispenser. This configuration is essential for protecting downstream equipment like desiccant air dryers and sensitive pneumatic instruments from oil aerosols and sub-micron debris. For contractors managing industrial air compressor maintenance, this element provides the specific coalescence required for "oil-free" air applications including electronics manufacturing and food-grade air processing.

Key Benefits for Technicians

• High-Efficiency Coalescence: Removes 99.999+% of oil aerosols and sub-micron particulates down to 0.01 micron.
• Optimized Flow Dynamics: The matrix blended fiber media maximizes surface area to ensure low pressure drop and reduced energy consumption.
• Rugged Construction: Features stainless steel inner and outer cores for superior strength and chemical resistance against synthetic lubricants.
• System Protection: Effectively prevents oil carryover that can foul refrigerated air dryers and pneumatic valves.
• Easy Installation: The push-on design with a piston-type element-to-housing seal prevents unfiltered air bypass.

Common Questions

A Grade 5 is a high-efficiency filter (0.01 micron / 0.008 ppm), whereas the Hankison Grade 3 E3-16-03 is an ultra-high efficiency element providing significantly lower remaining oil content (0.0008 ppm), making it the standard for critical "oil-free" air requirements.

For optimal performance, replace the element when the differential pressure indicator signals a restriction or during scheduled annual compressor system maintenance to ensure air quality standards are maintained.

While the E3-16-03 filter is excellent at coalescing fine aerosols, it is best practice to install a Grade 7 or Grade 11 moisture separator upstream if heavy liquid loads are present to prevent premature saturation of the Grade 3 media.
