Coalescing Filters

Core Technical Specifications

Absolute Filtration Precision: 1 μm

Max Continuous Working Pressure: 1.6 MPa

Operating Temperature Range: -10°C ~ +80°C

Max Inlet Relative Humidity: ≤75% RH

Clean & low-humidity general workshop: 6,000–8,000 operating hours or 12 months

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

Mandatory Replacement Trigger: Differential pressure ΔP ≥ 0.07 MPa or visible water/oil carryover downstream

Differential Pressure Threshold

Initial Pressure Drop of New Element: ≤0.018 MPa

Alarm Replacement Pressure: ≥0.07 MPa

Structural Features

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

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

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

Key Product Advantages

Protect downstream high-precision ultra-coalescing and carbon filters to cut total maintenance cost

Traps over 90% of bulk liquid water and oil droplets in compressed air, drastically reduces contaminant load on CXNE00800 ultra-coalescer, and extends service life of CCNE00800 activated carbon filters by more than 50%.

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

Large pleated surface area holds massive 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 large liquid droplets and drains by gravity, avoiding re-atomization of liquid carried by high-speed airflow into downstream pipelines.

Corrosion-resistant metal frame adapts to harsh industrial workshop environments

Galvanized steel cages resist rust and condensate corrosion, suitable for long-term continuous operation in general machining, plastic molding, sandblasting and light paint workshops.

Threaded quick-install design for single-person fast maintenance

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

Coalescing Working Principle

Pre-filtered compressed air from CPNE00800 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.

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 pneumatic equipment, light-duty painting lines, textile factory central air supply, packaging machinery, small mining pneumatic tools.
