Standard Replacement Cycle

4,000 working hours / 12 months under clean industrial air conditions; shorten to 2,000–3,000 hours in dusty, high-humidity spray workshops. Replace when differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of new element: ≤0.014 MPa

Mandatory replacement alarm threshold: ΔP ≥ 0.07 MPa

Sealing & Support Construction

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

Seal System: Integral full-circle NBR nitrile rubber gasket, zero air bypass, resistant to aging caused by compressor oil and acidic condensate

Inner & Outer Support Cage: Double-layer perforated 304 stainless steel mesh, structural reinforcement to avoid media collapse under full rated airflow

Key Product Advantages

Third-stage ultra-fine polishing barrier to protect downstream QD activated carbon filter

Installed after DD medium coalescing filter, this PD-grade element intercepts invisible trace submicron oil mist and micro water droplets that medium filters cannot separate. It drastically reduces liquid contamination load on terminal activated carbon filter elements, extends their service life and cuts spare parts costs.

High dirt and liquid holding capacity for long stable continuous operation

Thick deep-pleated microglass matrix holds large volumes of oil and condensate. The outer red drainage foam accelerates liquid separation and gravity discharge, slowing pressure rise in humid workshop environments and reducing unplanned downtime caused by frequent filter replacements.

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

Heat-cured borosilicate microglass composite paired with stainless steel support mesh prevents glass fiber powder from shedding into air pipelines, protecting micro spray nozzles, tiny laser optical lenses and miniature solenoid valves from clogging failures.

Optimized low permanent differential pressure to reduce compressor power consumption

Uniform gradient pore layout minimizes airflow resistance throughout the entire service cycle. Stable low backpressure lowers continuous power consumption of small screw compressors, cutting long-term factory electricity expenses.
