Key Product Features

High-efficiency coalescing separation

Micro glass fiber medium aggregates tiny submicron oil mist into large liquid oil droplets, which flow back to the lubricating system through the return oil pipeline, greatly reducing compressor oil consumption.

Low initial pressure drop

Optimized pleating structure provides large effective filtration area, maintains low airflow resistance during long-term continuous operation and saves compressor power cost.

Large oil holding capacity

Gradient composite filter material can store massive separated lubricant, extend service cycle and reduce maintenance frequency.

Reinforced internal metal support cage

Prevent filter layer collapse, deformation and damage under long-term high-pressure, high-flow operation.

Anti-corrosion & high temperature resistance

Filter media and metal components resist oxidation and aging under continuous high-temperature oil-gas mixing environment.

Working Principle

Oil-gas mixture discharged from screw compressor flows through the glass fiber filter layer. Submicron oil mist particles are captured and coalesced into large oil droplets, which settle to the bottom of the separator tank and return to the oil tank via the oil return pipe, while clean compressed air flows out for post-processing purification.

Application & Industries

Widely used in general machinery, packaging, textile, metal processing, spray coating, mining, food & pharmaceutical, pneumatic equipment production lines.
