Coalescing Filters

Part No: 38446381

Core Technical Specifications

Absolute Filtration Accuracy: Solid particles, liquid oil & water aerosols ≥1 μm

Filtration Efficiency: 99.925% removal efficiency for 1μm oil mist aerosols, certified per ISO 12500-1 multi-pass test standard

Multi-layer extra deep-pleated proprietary HV borosilicate gradient microglass composite media, outer integrated thick hydrophobic & oleophobic PU anti-re-entrainment drainage foam. Built-in liquid diversion barrier prevents coalesced liquid from being re-entrained by ultra-high-speed large-volume industrial airflow.

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: -10°C ~ 80°C, high-temperature resistant industrial media

4,000 operating hours / 12 months (whichever comes first) under clean low-dust industrial environments; shorten to 2,000–3,000 hours for automotive paint spray booths, metal foundries and high-humidity dusty workshops. Mandatory replacement when differential pressure ΔP ≥ 0.06 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of brand-new element: ≤0.012 MPa

Mandatory alarm replacement threshold: ΔP ≥ 0.06 MPa

End Cap & Base: Thick carbon steel molded threaded top cap + flat metal bottom base, anti-rust coated surface

Seal System: One-piece molded full-face FKM fluorocarbon rubber gasket, zero bypass leakage, excellent resistance to high heat, compressor oil and acidic condensate corrosion

Inner & Outer Support Cage: Double-layer heavy-duty perforated 304 stainless steel mesh, reinforced anti-collapse structure to withstand full rated ultra-large airflow deformation

Key Product Advantages

It drastically reduces liquid contamination load on downstream high-precision filter elements, extends overall consumable service cycle and cuts factory large-scale maintenance expenditure.

Ultra-large dust & oil holding capacity with stable low differential pressure for 24/7 heavy industrial production

Proprietary extra deep-fold microglass matrix stores huge volume of oil sludge, carbon deposits, pipeline rust and solid dust without rapid pressure rise, perfectly matching non-stop round-the-clock heavy-duty production for large manufacturing plants, energy stations and automotive factories. Outer high-performance hydrophobic foam rapidly drains all separated liquid to the filter bottom drain port and minimizes oil re-entrainment risk in turbulent ultra-large airflow.

Heat-stabilized glass fiber media eliminates fiber shedding and full-system pipeline contamination

High-temperature fully cured borosilicate microglass media maintains complete structural integrity under sustained 80°C operating temperature without softening, pulverization or fiber shedding. Zero glass fiber debris enters large-bore industrial piping to block heavy spray manifolds, industrial laser optical lenses and large proportional process control solenoid valves.

Working Principle

Ultra-large-volume pre-dried compressed air flows through the long filter cartridge from outside to inside central core:

Large water droplets and coarse solid impurities are trapped by outer thick hydrophobic foam and drain down to the large filter bowl drain port by gravity.

1μm oil-water micro-aerosols collide and coalesce into large separable liquid droplets while passing through multi-layer gradient borosilicate microglass media.

Outer integrated anti-re-entrainment foam barrier prevents separated liquid oil and water from being re-carried by high-speed ultra-large-volume industrial compressed airflow.

Collected oil and condensate are automatically discharged via heavy-duty industrial electronic zero-loss drain valve.
