Structural Features

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

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

Integrated FKM fluororubber sealing ring, excellent compatibility with all compressor lubricants, zero bypass air leakage

Static conductive fiber framework eliminates static ignition risk in oil-air mixed industrial environments

Key Product Advantages

Depth-type gradient polyester media with high dirt holding capacity & gentle pressure rise curve

3D wrapped depth microfiber media provides large effective storage space for oil sludge, dust and liquid 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 large liquid droplets and drains by gravity, avoiding re-atomization of liquid carried by high-speed airflow into downstream precision production pipelines.

Lightweight anti-corrosion compact structure suitable for small-medium flow workshop systems

Stainless steel support mesh + plastic end caps resist condensate and oil vapor erosion, compact size saves pipeline installation space, stable performance under long-term continuous operation.

Double-port plug-in tool-free quick maintenance design

Isolate and vent housing pressure, pull out old cartridge and insert new element within 3 minutes without special tools, minimizing unplanned production downtime.

Coalescing Working Principle

Pre-filtered compressed air from 1C486043 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 depth gradient polyester media; tiny liquid particles collide, aggregate and coalesce into continuous liquid film that flows back down to drain.

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

Application Scope

General mechanical machining, metal welding, small injection molding pneumatic equipment, light manual painting lines, laboratory auxiliary instrument gas supply, small food packaging machinery, textile branch workshop air supply.
