Key Product Advantages

Full Lubrication Circuit Protection to Extend Airend Service Life

Traps metal abrasive chips, carbon deposits and sludge mixed in circulating oil. Supplies clean lubricant to screw rotors, bearings and gear assemblies, effectively reducing rotor scratch wear and prolonging service life of airend, air-oil separator and downstream pipeline precision filters.

Low Initial Differential Pressure for Energy Saving

Uniform deep-pleated filter media enlarges effective filtration area and optimizes internal oil flow passages. Maintains stable low pressure drop under 24/7 full-load continuous operation, avoiding increased motor load and extra power consumption caused by blocked oil circuit.

Large Dirt Holding Capacity & Anti-Clog Performance

Gradient depth filtration matrix stores massive metal debris and oil sludge, resists clogging from deteriorated high-temperature lubricant, suitable for long-cycle uninterrupted industrial production.

Dual Built-in Safety Valves to Prevent Equipment Failure

Bypass valve: Automatically opens under severe clogging to guarantee continuous oil supply to airend, avoiding dry grinding and sudden shutdown.

Anti-drain back valve: Retains oil inside filter after unit shutdown to eliminate metal dry friction during restart.

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 uninterrupted oil supply.

Application & Industries

Core wearing spare part installed on the main oil circulation pipeline of Gardner Denver 26C26 series 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.
