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

Outer integrated drainage fleece automatically collects condensed water & oil and guides liquid downward to housing auto drain valve by gravity

Single full-circle oil-resistant EPDM top sealing ring, 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 medium coalescer 39241192 cannot intercept, limiting outlet liquid oil below 0.01 ppm. Extends service life of 39241198 activated carbon filters by over 60% and significantly cuts overall workshop maintenance costs.

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 even under continuous heavy oil load, reducing extra power consumption of upstream air compressors.

Integrated hydrophobic drainage fleece eliminates secondary liquid re-entrainment

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

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

Full stainless steel cages resist rust and acidic condensate erosion, suitable for long-term continuous operation in heavy laser cutting, mass pharmaceutical filling, large auto painting and bulk food packaging 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 large-scale production downtime.

Coalescing Working Principle

Pre-cleaned compressed air from 39241192 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 complete cartridge replacement.

Application Scope

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