Sealing & Structural Construction

Outer Support Cage: Rigid perforated anti-static polypropylene, corrosion-proof, prevents media deformation under large airflow surges

Dual-Layer Barrier: Outer foam pre-filter captures large water/oil droplets; inner ultra-fine glass fiber coalesces submicron mist

Sealing System: Integrated high-temperature EPDM full-circle O-ring, zero bypass air leakage

Anti-Static Design: Conductive composite framework eliminates static charge buildup risk in oil-air mixed environment

Key Product Advantages

It limits liquid oil content below 0.01 ppm, drastically extending the service life of downstream E184KA activated carbon elements by over 60%.

Oversized deep-pleated gradient glass fiber media with massive contaminant holding capacity

Large pleat surface area provides exceptional oil sludge storage capacity, slowing differential pressure rise across the full service cycle even under 18.4 m³/min high flow. Layered coalescing structure continuously aggregates micro oil droplets into liquid film for gravity condensate drainage, maintaining consistent ultra-high separation efficiency without performance decay.

Ultra-low permanent pressure loss reduces large compressor energy consumption

Optimized flow channel design and high-permeability media deliver up to 50% lower steady-state pressure loss compared to generic aftermarket filters, cutting continuous power draw of upstream large screw compressors and lowering long-term factory electricity costs.

Anti-static all-plastic support structure eliminates explosion hazard in high-oil environments

Conductive polypropylene cage dissipates static charge generated by high-speed large-volume air and oil mist friction, removing fire risks in painting, chemical and food processing workshops.

Bayonet plug-and-play maintenance design for rapid single-person replacement

No special tools required; fully vent filter housing pressure, unlock top bayonet cap, extract old cartridge and install new unit within 1 minute, minimizing unplanned large-scale production downtime.

Coalescing Working Principle

Low-oil compressed air (≤1 ppm liquid oil) from E184KD medium coalescer flows into the outer foam pre-filter layer of E184KE. Large water and oil droplets are trapped and drain downward via gravity condensate port.

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

Fully polished compressed air (≤0.01 ppm residual liquid oil) passes through the inner barrier layer and flows out to the E184KA activated carbon final stage.

After long-term service, media pores become fully saturated with oil sludge; differential pressure rises sharply and separation efficiency drops, requiring full cartridge replacement.

Application Scope

Automotive large component electrostatic painting workshops, heavy-duty precision metal laser cutting factories, large electronic component cleanrooms, cosmetic & pharmaceutical mass aseptic filling lines, large food sterile packaging production, central laboratory high-purity instrument gas supply, medical central breathing air pretreatment.
