Hankison E5-12 Aerolescer Element

The Hankison E5-12 Aerolescer Element is a high-efficiency oil removal filter engineered for critical downstream protection in compressed air systems. Built to withstand rigorous industrial environments, this coalescing filter element features a two-stage filtration process including a coated, closed-cell foam sleeve for pre-filtration and a pleated microfiber media matrix for ultra-fine coalescence. It provides high-tier air quality by removing solids and liquid aerosols down to 0.01 micron with a 99.99% efficiency rating and a maximum residual oil content of 0.01 ppm. Designed as a direct replacement for HKN-53-12 and HKN-E5-12, this Grade 5 filter is essential for protecting desiccant dryers and ensuring oil-free air for pneumatic tools, food processing, and pharmaceutical applications. Professional technicians rely on its corrosion-resistant inner and outer cores to maintain low pressure drop and long-term structural integrity under constant flow conditions.

Key Benefits:

• Achieves 0.01 micron filtration to protect sensitive pneumatic components from particulate damage.
• Superior coalescing efficiency reduces oil carryover to 0.01 ppm, ensuring high-purity air.
• Directly compatible with HKN-53-12 and HKN-E5-12 housings for seamless field replacement.
• Dual-stage matrix blended fiber media maximizes surface area for extended service life and minimal pressure loss.
• Rugged corrosion-resistant cores provide structural stability in demanding HVACR and industrial air systems.

Common Questions:

Is the E5-12 suitable for protecting desiccant air dryers?
Yes, this compressed air filter is specifically designed for installation upstream of desiccant or membrane dryers to prevent oil contamination of the desiccant bed, which is critical for maintaining dew point performance.

What is the difference between Grade 5 and other Hankison elements?
The Grade 5 E5-12 element provides high-efficiency oil removal (0.01 micron). It is typically used as a second stage of filtration, following a Grade 7 or 9 pre-filter, to provide the ultra-clean air required for technical applications.

When should the Hankison E5-12 be replaced?
While service life depends on air quality, technicians should monitor the pressure drop across the inline filter housing. Replacement is generally recommended when the pressure differential reaches 7-10 psid or during annual system maintenance.
