Structural Features

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

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

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

Static conductive fiber framework eliminates static ignition risk 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 MKO-1210X medium coalescer cannot intercept, limiting outlet liquid oil below 0.01 ppm. It extends service life of MKO-1210A activated carbon filters by over 60% and significantly reduces 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 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.

Wide-temperature corrosion-resistant metal frame for harsh industrial workshop conditions

Galvanized steel cages resist rust and condensate corrosion, suitable for long-term continuous operation in laser cutting, pharmaceutical aseptic filling, food packaging and automotive painting workshops.

Buckle-type tool-free quick-install design for single-person fast maintenance

Isolate and vent housing internal pressure, pull out old cartridge and install new unit within 5 minutes without special tools, minimizing unplanned production downtime.

Coalescing Working Principle

Pre-cleaned compressed air from MKO-1210X medium coalescer enters outer polyester drainage fleece layer; large water and oil droplets are intercepted and flow downwards to 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.

Ultra-polished compressed air with residual liquid oil ≤0.01 ppm flows downstream to MKO-1210A activated carbon final stage for oil vapor and oily odor elimination.

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 factories, pharmaceutical aseptic filling lines, food sterile packaging production, precision electronic cleanrooms, laboratory high-purity instrument gas supply, medical breathing air pretreatment.
