Mandatory Replacement Trigger

Differential pressure ΔP ≥ 0.05 MPa or visible oily odor/contamination downstream

Differential Pressure Thresholds

Initial pressure drop of new element: ≤0.012 MPa

Blockage alarm differential pressure: ≥0.05 MPa

Key Product Advantages

Captures invisible micro oil mist and fine dust, meeting strict air requirements for painting, electronics and pharmaceutical production.

Large dirt holding capacity with slow pressure rise

Deep folded gradient glass fiber media stores massive oil sludge and dust, slowing differential pressure growth and reducing long-term compressor power consumption.

Full perimeter dual-end sealing design for zero bypass leakage

Integrated molded end caps with embedded nitrile gaskets prevent short-circuit unfiltered airflow, maintaining stable long-term filtration efficiency.

Working Principle

Pre-filtered compressed air (processed by AO grade pre-filter) flows from outside to inside through gradient glass fiber media.

Coarse liquid water droplets and large solid dust are trapped by outer pre-layer and drain downwards to filter bowl via gravity.

Invisible 0.01μm ultra-fine oil aerosols collide with glass fiber filaments, coalesce into large liquid oil droplets and flow down for drainage.

Ultra-clean compressed air flows downstream to ACS activated carbon filter for final oil vapor and odor adsorption.

Filter media cannot be cleaned, washed or regenerated; full element replacement is required once saturated by oil sludge and dust contaminants.

Application Scope

Automotive electrostatic painting workshops, precision electronic component assembly, pharmaceutical sterile production, medical dental air supply, food sterile packaging, laboratory analytical instruments, laser cutting & laser marking equipment.
