Product Features

Compact multi-gradient dense glass fiber media with stable oil mist storage capacity, anti-saturation under continuous light & medium loads, stably control residual oil ≤3 ppm throughout full service cycle.

Moderate short deep-pleated low-resistance cylinder, slow differential pressure rising under long full-load running, effectively reduce power consumption of 37–55kW small main unit.

Double-layer perforated galvanized anti-static inner & outer support cages, anti-corrosion & anti-pressure surge; filter media will not deform or collapse under rated airflow, eliminate static ignition risk of oil mist. Composite fiber gasket resists high temperature aging, reliable sealing under frequent start-stop & temperature fluctuation, avoid oil bypass and excessive oil carry-over failure.

Product Description

It adopts high-efficiency gradient glass fiber coalescing separation technology to intercept micron-level lubricant oil aerosol in low & medium-flow compressed air. Separated lubricant flows back to compressor main unit via bottom central gravity oil return tube for recycling, greatly cut lubricating oil consumption and extend overall machine maintenance interval.

It fully protects downstream refrigerated dryers, adsorption dryers, precision pneumatic valves and spraying equipment, lower breakdown frequency and maintenance cost of small air post-processing purification system.
