Coalescing Filters

Part No: 5315201001

Core Technical Specifications

Filtration Grade: KB Primary Coarse Dust & Bulk Liquid Prefilter

Absolute Filtration Precision: Solid particles ≥3 μm, bulk free water droplets

Filtration Efficiency: 99.9% capture efficiency for 3μm pipeline rust, welding slag and dust contaminants

Filter Media Structure: Multi-layer gradient deep-pleated cellulose-glass fiber composite, thick white outer porous foam for capturing large water droplets and coarse solid impurities

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: 3°C ~ 66°C

Standard Replacement Interval

4,000 operating hours under clean indoor industrial environments; shorten to 2,000–3,000 hours for dusty, high-humidity workshops. Replace immediately once differential pressure hits alarm threshold.

Differential Pressure Replacement Thresholds

Initial pressure drop of brand-new element: ≤0.010 MPa

Mandatory replacement alarm point: ΔP ≥ 0.06 MPa

Sealing & Support Construction

End Cap Assembly: Reinforced black PA polyamide lock base with built-in flow diversion ribs

Seal System: Single full-circle NBR nitrile rubber O-ring, zero air bypass leakage, resistant to compressor oil and acidic condensate aging

Inner & Outer Support Cage: Double-layer perforated 304 stainless steel mesh, anti-collapse under full rated continuous airflow

Key Product Advantages

It dramatically reduces particle and liquid load on subsequent coalescing and carbon elements, cutting overall factory spare parts and maintenance costs.

High dust & liquid holding capacity with slow pressure rise

Thickened composite fiber plus outer thick white foam dual interception design delivers massive dust storage and liquid drainage capacity. Even in humid, dusty production environments, it avoids rapid differential pressure buildup and frequent premature replacement downtime.

Stable solidified media structure with zero fiber shedding secondary contamination

Heat-set composite fiber matched with double-layer stainless steel support mesh prevents fiber powder detachment into pipelines, protecting downstream spray guns, laser optical lenses and precision miniature pneumatic valves from blockage failure.

Ultra-low initial pressure drop to cut compressor energy consumption

Optimized pleat spacing and uniform pore distribution minimize startup airflow resistance. Stable low backpressure reduces continuous power loss of screw air compressors, lowering long-term factory electricity operating expenses.

Working Principle

Large solid dust, rust particles and bulk water droplets are first trapped by the outer white foam layer; most free water drains down to filter bowl via gravity;

Remaining fine dust and micro water droplets are intercepted by multi-layer deep-pleated composite fiber media;

Primarily cleaned air flows downstream into KE medium coalescing filter for secondary oil-water separation treatment;

Application Industries

Metal machining workshops, laser marking & cutting equipment, textile printing factories, automated packaging production lines, standalone screw compressor stations, plastic injection molding auxiliary air supply, food aseptic packaging equipment, general pneumatic tool gas source for manufacturing plants.
