Coalescing Filters

Part No: ZS1133764

Core Technical Specifications

Absolute Filtration Precision: Solid particles ≥1 μm, liquid oil/water aerosols ≥1 μm

Filter Media Structure: Multi-layer deep-pleated gradient borosilicate microglass composite, integrated hydrophobic & oleophobic drainage foam outer layer to eliminate liquid re-entrainment

Operating Limits

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: 1.5°C ~ 80°C

Standard Replacement Interval

4,000 operating hours / 12 months under clean industrial conditions; shorten to 2,000–3,000 hours in high-humidity, dusty workshops. Replace immediately once differential pressure hits alarm threshold.

Differential Pressure Replacement Thresholds

Initial pressure drop of new element: ≤0.012 MPa

Mandatory replacement alarm trigger point: ΔP ≥ 0.06 MPa

Sealing & Support Construction

End Caps: Reinforced black PA polymer locking head with integrated flow diversion ribs

Seal System: Integrated full-circle NBR nitrile rubber gasket, zero air bypass leakage, resistant to compressor oil, acidic condensate and long-term aging

Inner & Outer Support Cage: Perforated stainless steel protective mesh, anti-collapse under full rated continuous airflow

Key Product Advantages

Installed after ZS1133763 Grade P coarse prefilter, this G-grade cartridge intercepts bulk condensed free water, large oil droplets and 1 μm micron-level oil mist that pass the primary prefilter. It drastically reduces liquid contamination load on terminal ultrafine and carbon cartridges, extends their service life and cuts factory spare parts & maintenance expenses.

Large oil & liquid holding capacity for stable long-cycle continuous operation

Thick deep-pleated microglass matrix provides massive liquid retention volume. It resists rapid pressure rise in humid production workshops with underperforming aftercoolers or refrigerated dryers, minimizing unplanned production downtime from frequent filter swaps.

Heat-stabilized integrated media, zero fiber shedding to avoid secondary pipeline contamination

Heat-cured solidified microglass composite paired with stainless steel support mesh prevents fiber powder detachment under long-term airflow impact. No glass fiber debris will block spray guns, laser optical lenses and miniature pneumatic control valves.

Ultra-low permanent differential pressure to reduce air compressor energy consumption

Uniform gradient pore layout minimizes airflow resistance throughout the full service lifespan. Stable low backpressure cuts continuous power draw of small/medium screw air compressors and lowers long-term factory electricity costs.

Working Principle

Preliminarily cleaned compressed air flows through the filter cartridge from outside to inside:

Residual large condensed water droplets and fine solid particles are trapped and drained by the outer hydrophobic foam layer, flowing down to filter bowl via gravity;

1 μm oil & water micron aerosols collide, coalesce and form large separable liquid droplets while passing through multi-layer gradient borosilicate microglass media;

The outer anti-re-entrainment foam prevents coalesced liquid droplets from being re-carried into high-speed compressed airflow;

Application Industries

Small automotive spray booths, mini laser marking & cutting equipment, textile printing auxiliary air supply, small packaging automation lines, standalone small screw compressor stations, plastic injection molding auxiliary air supply, food & beverage processing auxiliary gas, laboratory analytical instrument air source, general pneumatic tool gas source for small manufacturing plants.
