Key Product Advantages

Full Lubrication Circuit Protection & Airend Life Extension

Captures metal abrasive particles, carbon deposits and sludge mixed in circulating compressor oil. Delivers clean lubricant to screw rotors, bearings and gear assemblies, effectively reducing rotor scratch wear and extending service life of airend, air-oil separator and downstream pipeline filters.

Low Initial Differential Pressure for Energy Saving

Uniform deep-pleated filter medium expands effective filtration area and optimizes internal oil flow channels. Maintains stable low pressure drop during long continuous operation, avoiding increased motor load and extra power consumption caused by clogged oil circuit.

Large Dirt Holding Capacity & Anti-Blockage Performance

Gradient depth filtration matrix stores massive metal debris and oil sludge, resists blockage from high-temperature aging lubricant, suitable for 24/7 full-load industrial continuous operation.

Dual Safety Valve Design for Failure Prevention

Built-in bypass valve automatically opens under severe clogging to guarantee uninterrupted oil supply to airend and prevent dry grinding shutdown failure. The anti-drain back valve retains oil inside filter after machine shutdown to eliminate dry startup abrasion.

Working Principle

Circulating lubricant oil inside the compressor flows radially from outside to inside through filter medium. Metal wear chips, carbon sludge and solid impurities are intercepted and trapped on filter fiber surface. Clean oil flows out through central threaded hole to lubricate airend bearings and rotor meshing surfaces. When filter medium is severely blocked, the bypass valve activates automatically to maintain continuous oil supply.

Application & Industries

Core consumable spare part installed on the main oil circulation pipeline of Atlas Copco oil-injected screw air compressors.

Widely applied in machinery manufacturing, automotive electrostatic spraying, packaging printing, textile plants, food sterile packaging, laser cutting equipment, pharmaceutical clean workshops and centralized factory compressed air supply stations.
