Product Features

Oversized multi-gradient high-density glass fiber media with massive oil mist storage capacity, anti-saturation under long-term full heavy load, stably control residual oil ≤3 ppm throughout full service cycle.

Extra tall deep-pleated low-resistance cylinder, slow differential pressure rising during continuous ultra-high-flow operation, effectively reduce power consumption of 280–355kW super large main unit.

Double-layer thickened perforated anti-static inner & outer support cages, anti-corrosion and anti-pressure surge; filter media will not deform or collapse under maximum airflow, eliminate static ignition risk of oil mist.

Heavy-duty multi-hole flat flange fully matched original oil tank mounting dimension. Composite gasket resists high temperature aging, reliable sealing under frequent start-stop and 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 ultra-large volume compressed air. Separated lubricant flows back to the main unit through the central bottom gravity oil return tube for recycling, greatly reduce lubricating oil consumption and extend overall machine maintenance interval.

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