Key Product Advantages

Critical polishing protection for downstream activated carbon filters

Traps residual submicron liquid oil mist that P040AO medium coalescer cannot intercept, limiting outlet liquid oil below 0.01 ppm. Extends service life of expensive P040ACS carbon filters by over 60% and cuts overall maintenance expenditure.

Deep-pleated proprietary glass fiber media with high dirt holding capacity & gentle pressure rise curve

Large effective filtration area stores massive oil sludge, water and fine dust; differential pressure rises slowly through the full service cycle to reduce extra power consumption of upstream air compressors.

Integrated hydrophobic drainage fleece prevents secondary liquid re-entrainment

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

Stainless steel anti-corrosion framework suitable for humid industrial environments

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

Bayonet tool-free quick maintenance design

Isolate and vent housing pressure, twist open bayonet cap, extract old cartridge and install new unit within 4 minutes without special tools, minimizing unplanned production downtime.

Coalescing Working Principle

Pre-treated compressed air (≤1 ppm liquid oil) from P040AO medium coalescer enters outer polyester drainage fleece; large water and oil droplets separate and drain downwards to the housing drain port by gravity.

Remaining 0.01 μm submicron 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.

Ultra-polished compressed air (residual liquid oil ≤0.01 ppm) flows downstream to P040ACS activated carbon stage for oil vapor and odor removal.

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

Application Scope

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