Key Product Features

Multi-Layer High-Efficiency Two-Stage Oil Mist Coalescence

Four-layer gradient glass fiber composite traps micro oil aerosols generated by screw rotor compression. Coalesced liquid oil flows back to compressor oil tank via central oil return pipe, effectively reducing oil consumption and guaranteeing low-oil clean compressed air output.

Low Initial Differential Pressure & Energy Saving

Large deep-pleated filter area optimizes internal airflow channels to minimize pressure loss. Avoids extra power consumption caused by clogged separator, lowering long-term factory operation electricity cost.

Strong Oil Holding & Anti-Saturation Capacity

Thick multi-gradient fiber matrix stores massive coalesced lubricant oil, extends maintenance cycle, resists high-temperature oil aging and resin blockage, suitable for long continuous running conditions.

High-Temperature Anti-Corrosion Reinforced Structure

Galvanized metal mesh and high-temperature sealing gasket withstand long-term high-temperature oil-gas environment; prevents media rupture and fiber shedding to avoid secondary oil contamination of downstream pipeline filters and equipment.

Working Principle

Mixed air-oil gas discharged from screw rotor flows radially from outside to inside through the separator glass fiber media. Submicron oil mist particles collide, aggregate and condense into large liquid oil droplets on fiber surface. Gravity pulls oil down to the separator bottom, then flows back to compressor oil tank through central oil return tube; low-oil dry compressed air flows out to post-processing precision filter pipeline.

Application & Industries

Core wearing spare part installed inside screw compressor oil-gas separation tank.

Widely used in automotive manufacturing, packaging printing, textile factories, electrostatic spray workshops, food sterile packaging, laser cutting equipment and centralized factory compressed air stations.
