Coalescing Filters

Part No: C-360-85

Core Technical Specifications

Filtration Grade: C General Medium Coalescing Grade

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

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

4,000 operating hours or 12 months (whichever comes first) under clean low-dust environments; shorten to 2,000–2,500 hours for paint booths, foundries and high-temperature gas stations. Mandatory replacement when differential pressure ΔP ≥ 0.06 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of new element: ≤0.012 MPa

Mandatory alarm replacement threshold: ΔP ≥ 0.06 MPa

End Cap: One-piece molded solid urethane anti-corrosion end caps

Seal System: Integrated FKM fluorocarbon full-circle sealing gaskets, excellent resistance to high heat, compressor oil and acidic condensate, zero bypass leakage

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

Key Product Advantages

Mid-stage primary coalescing barrier to protect downstream high-precision and carbon filters

Installed after P360-85 particulate prefilter and before CU360-85 ultrafine filter, it intercepts massive condensed pipeline water, rust scale and large 1μm liquid oil mist. It drastically reduces liquid contamination load on downstream high-precision elements, extends overall consumable service cycle and cuts factory maintenance costs.

Extra-large dust & oil holding capacity with stable low differential pressure

Proprietary deep-pleated glass fiber matrix holds large volume of oil sludge, carbon deposits and solid dust without rapid pressure rise, suitable for 24-hour non-stop heavy-duty production lines. Outer hydrophobic foam quickly drains coalesced liquid down to filter bowl drain port and greatly reduces oil re-entrainment risk.

Ultra-high temperature stable glass fiber media with zero fiber shedding

High-temperature cured borosilicate microglass maintains stable structural integrity under sustained 232°C operating temperature without softening, pulverization or fiber shedding, preventing blockage of downstream precision equipment such as spray guns, gas turbine nozzles and laser optical lenses.

Low permanent differential pressure energy-saving design to cut compressor power consumption

Uniform gradient pleat layout delivers minimal airflow resistance over the full service cycle. Stable low backpressure reduces continuous motor loading of large industrial air compressors and gas turbines, lowering long-term workshop electricity & fuel operating costs.

Finite H series drop-in quick maintenance design

Unified full-length cylindrical drop-in positioning structure perfectly fits FT/FF85 filter housing. Single technician can complete full element pull-out replacement within 5 minutes after full system pressure relief; complete disassembly of filter cylinder is not required.

Working Principle

High-volume pre-dried compressed air / industrial gas flows through the filter cartridge from outside to inside:

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

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

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

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