Product Features

Deep multi-layer pleated filter medium with large dirt holding capacity, effectively capture metal wear debris, lubricant carbon sludge, oil oxidation colloid and pipeline rust impurities to keep circulating oil clean.

Dual built-in safety valve structure:

Anti-drainback valve locks residual oil inside filter after shutdown to prevent dry-start abrasion of main airend and bearing group;

Bypass valve opens at 1.3bar preset differential pressure when filter element is blocked, ensuring uninterrupted oil circulation and avoiding compressor overheat trip-off.

Thick electrophoretic anti-corrosion steel shell + high-temperature resistant NBR sealing gasket, stable leakproof performance against long-time equipment vibration and fluctuating oil pressure.

Product Description

Core consumable part, installed on main oil pipeline to purify circulating lubricant, protect host airend and bearing assembly, extend oil replacement cycle and reduce unexpected equipment breakdown maintenance cost.
