Coalescing Filters

Core Technical Specifications

Filtration Grade: Medium coalescing pre-filter stage, removes solid particulate dust, bulk condensed water droplets and medium-size compressor lubricant aerosols

Absolute Filtration Precision: 1 μm

Max Continuous Working Pressure: 1.6 MPa

Operating Temperature Range: 3°C ~ +66°C

Clean & low-humidity general workshop: 4,000–6,000 operating hours or 12 months

Paint shop, high humidity, heavy dust & oil load, 24/7 continuous full-load operation: 3,000–5,000 hours

Initial Pressure Drop of Brand-New Element: ≤0.018 MPa

Alarm Replacement Differential Pressure: ≥0.07 MPa

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

Outer integrated drainage fleece automatically 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 structure eliminates static ignition risk in oil-air mixed working environments

Key Product Advantages

Critical pre-protection for downstream high-precision ultra-coalescing and carbon filters to reduce total maintenance expenditure

Traps over 90% of bulk liquid water and oil droplets inside compressed air, greatly reduces contaminant load on P040AA ultra-coalescer, and extends service life of expensive P040ACS activated carbon filters by more than 50%.

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

Large effective pleated filtration area holds massive oil sludge, water and solid 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 rapidly coalesces large liquid droplets and drains by gravity, avoiding re-atomization of liquid carried by high-speed airflow into downstream precision production pipelines.

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

Full stainless steel inner & outer cages resist rust and condensate corrosion, suitable for long-term continuous operation in general machining, plastic molding, sandblasting and light-duty painting workshops.

Bayonet tool-free quick-install design for single-person fast maintenance

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

Coalescing Working Principle

Raw compressed air enters outer polyester drainage fleece layer; 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 ≤0.5 ppm flows downstream to P040AA 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

General mechanical machining, metal welding, injection molding small pneumatic equipment, light-duty manual painting lines, small textile factory air supply, packaging small machinery, laboratory auxiliary gas pretreatment.
