Perforated stainless steel inner & outer cages, anti-rust and anti-deformation under large-volume airflow fluctuations

Outer integrated drainage fleece rapidly collects condensed liquid and guides it downward to housing auto drain valve by gravity

Single full-circle oil-resistant EPDM top seal, zero bypass air leakage

Static conductive fiber framework eliminates static accumulation fire hazard in oil-air mixed industrial environments

Key Product Advantages

Critical polishing protection for expensive terminal activated carbon filters

Traps residual ultra-fine liquid oil mist that HEF1200AF medium coalescer cannot intercept, limiting outlet liquid oil below 0.01 ppm. Extends service life of costly HEF1200AC activated carbon filters by over 60% and significantly reduces overall workshop maintenance expenditure.

Oversized deep-pleated gradient glass fiber media with high dirt holding capacity & gentle pressure rise curve

Extra large pleated filtration area stores massive oil sludge, water and fine dust contaminants; differential pressure climbs slowly throughout full service cycle to cut extra power consumption of upstream air compressors.

Integrated hydrophobic drainage fleece prevents secondary liquid re-entrainment

Outer polyester fleece quickly coalesces bulk liquid droplets and drains by gravity, avoiding re-atomization of liquid carried by high-speed airflow into downstream precision production pipelines.

Stainless steel anti-corrosion framework adapts to harsh humid industrial workshop conditions

Full stainless steel support cages resist rust and acidic condensate erosion, stable performance in laser cutting, pharmaceutical aseptic filling, food packaging and automotive paint workshops.

Bayonet tool-free quick-install design for single-person fast maintenance

Isolate and vent housing internal pressure, twist open bayonet cap, extract old cartridge and install new unit within 5 minutes without special tools, minimizing unplanned production downtime.

Working Principle

Pre-cleaned compressed air from HEF1200AF medium coalescer enters outer polyester drainage fleece layer; large water and oil droplets separate and flow downwards to housing drain port by gravity.

Remaining 0.01 μm submicron liquid oil mist penetrates multi-layer gradient micro-glass fiber media; tiny oil particles collide, aggregate and coalesce into continuous liquid oil films on fiber surfaces.

The element cannot be cleaned or regenerated on-site. Once saturated with oil sludge and fine dust, differential pressure surges and separation efficiency fails, requiring full cartridge replacement.

Application Scope

Automotive electrostatic painting workshops, fiber laser cutting equipment, pharmaceutical aseptic filling lines, food sterile packaging production, precision electronic cleanrooms, laboratory high-purity instrument gas supply, medium-scale medical breathing air pretreatment.
