Blockage alarm differential pressure: ≥0.05 MPa

Key Product Advantages

Low & stable pressure drop for long-term energy saving

Patented Nautilus multi-layer wrapped gradient glass fiber structure ensures slow differential pressure rise throughout the full service life, effectively cutting continuous power consumption of air compressors.

Large dirt holding capacity to extend replacement cycle

Deep-folded multi-layer media stores massive oil sludge, fine dust and condensed water, reducing frequent replacement frequency and lowering overall maintenance costs.

Double O-ring integrated sealing design for zero bypass leakage

Epoxy fully sealed end caps with built-in dual O-rings prevent short-circuit unfiltered airflow, maintaining stable medium coalescing performance during long-term continuous operation.

Working Principle

Raw contaminated compressed air flows from outside to inside through gradient glass fiber filter media.

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

1 μm oil aerosols and fine solid particles collide with glass fiber filaments, coalesce into large liquid oil droplets and flow down for drainage.

The filter media cannot be cleaned, washed or regenerated. Full element replacement is required once saturated by oil sludge and dust contaminants.

Application Scope

Metal cutting & welding workshops, laser cutting & laser marking equipment, plastic injection molding production lines, food & beverage sterile packaging, textile textile machinery, pre-coalescing filtration before automotive electrostatic painting air pipelines.
