Differential Pressure Thresholds

Initial clean differential pressure: ≤0.008 MPa

Mandatory replacement alarm: ΔP ≥ 0.06 MPa

Sealing & Support Construction

End Caps: Machined aluminum alloy threaded top cap, integral one-piece forming

Seal: Built-in double NBR nitrile rubber O-rings, zero air bypass leakage

Structure: Self-supporting sintered PE body, no separate inner/outer metal cage, anti-collapse under full airflow

Key Product Advantages

It greatly reduces abrasion and clogging of MF/SMF/AK cartridges, cutting overall maintenance and replacement costs.

Monolithic sintered PE media with ultra-high dust storage capacity

Uniform interconnected porous polyethylene structure provides far larger dirt holding volume than fiber pre-filters, resisting rapid clogging in heavy-dust compressor stations, reducing frequent shutdown for filter replacement.

Ultra-low airflow resistance & no fiber shedding risk

Solid sintered plastic media eliminates glass fiber shedding defects completely; uniform pore distribution maintains stable low pressure drop under 24/7 continuous operation, lowering air compressor power consumption and electricity costs.

Excellent hydrolysis & corrosion resistance

Inert polyethylene material resists condensed water, compressor oil mist and weak acid/alkaline condensate, suitable for high-humidity, hot compressed air working environments without media degradation.

Application Industries

General metal machining workshops, small screw compressor stations, textile printing, packaging equipment, small laser cutting machines, food small batch production, pneumatic automation equipment, shipboard small air systems.
