Structural Features

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

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

Single full-circle oil-resistant EPDM sealing ring, zero bypass air leakage

Key Product Advantages

Protect downstream high-precision elements and cut overall maintenance cost

Traps over 90% of bulk liquid water and oil droplets in compressed air, greatly reduces contaminant load on MKO-1210Y ultra-coalescer, and extends service life of expensive MKO-1210A activated carbon filters by over 50%.

Deep-pleated gradient media with high dirt holding capacity & gentle pressure rise curve

Large pleated surface area holds massive oil sludge, dust and liquid contaminants; differential pressure climbs slowly throughout 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 liquid droplets and drains by gravity, avoiding re-atomization of liquid carried by high-speed airflow into downstream production pipelines.

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

Galvanized steel cages resist rust and condensate corrosion, suitable for long-term continuous operation in compressor, sandblasting, painting and plastic molding workshops.

Buckle-type quick-install design for single-person fast replacement

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

Coalescing Working Principle

Pre-filtered compressed air from MKO-1210-P particulate filter enters outer polyester drainage fleece; large water and oil droplets are intercepted and flow downwards to drain port by gravity.

Remaining 1 μm oil mist and fine dust penetrate multi-layer gradient glass fiber; tiny liquid particles collide, aggregate and coalesce into continuous liquid film that flows back down to drain.

Processed compressed air with residual liquid oil ≤1 ppm flows downstream to MKO-1210Y for 0.01 μm ultra-fine polishing filtration.

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 component machining, metal welding, injection molding pneumatic equipment, general painting production lines, textile factory central air supply, packaging machinery, mining pneumatic tools.
