Screw Air Compressor Three Filters, Air Filter Element, Oil Filter Element, Oil Separation Element
Product Spotlights
I. Air Filter (Air Filter)
Function: Filters dust, silt, and fiber impurities in the air entering the air compressor, protecting the rotor of the screw unit.
Material: High-strength composite fiberglass / thickened wood pulp filter paper, with multiple pleated and folded expansion structure to increase dust retention space.
Performance: Filter efficiency ≥ 99.5%, low intake resistance, less prone to clogging; suitable for cement plants, grinding workshops, and mining environments with large amounts of dust.
Fault Impact: Poor-quality air filters are prone to clogging → insufficient air intake, increased load on the unit, and increased power consumption; dust entering the unit → rotor wear, carbon deposition, and jamming.
Replacement Cycle: 2000 hours in normal conditions, 800-1200 hours in dusty environments.
II. Oil Filter (Oil Filter)
Function: Filters metal debris, oil sludge, and gum impurities in the lubricating oil to keep it clean.
Material: High-precision microporous filter paper, reinforced central frame, resistant to pressure and impact.
Performance: Captures fine impurities, stabilizes lubricating oil quality, delays oil oxidation and deterioration, protects bearings and rotors.
Fault Impact: Filter blockage → increased oil pressure, high temperature shutdown; poor filtration → impurities wear the unit, shortening the overall machine lifespan.
Replacement Cycle: Synchronized with the oil, 2000-4000 hours.
III. Oil-Gas Separator (Oil Separation Core)
Function: Separates lubricating oil from compressed air, discharges compressed air, and returns oil to the oil tank.
Material: Multi-layer ultra-fine imported fiberglass composite filter material, layer-by-layer gradient filtration.
Performance: Outgoing air oil content ≤ 3 ppm, low pressure loss, energy saving; sealing rubber ring resistant to high temperature and oil corrosion, no oil leakage.
Fault Impact: Oil separation damage → large oil leakage in the outgoing air, frequent oil replenishment, oil contamination in the rear pipeline; blockage → excessive internal pressure in the unit, overload power consumption.
Replacement Cycle: 3000-4000 hours in normal conditions.
IV. General Advantages of the Entire Set of Three Filters
Fully compatible with various brands of screw compressors (Kai Shan, Hong Wu Huan, Jaguar, etc.), tight sealing, easy disassembly and assembly; using the three filters properly can save electricity, reduce lubricating oil consumption, reduce major machine overhauls, and lower production downtime and maintenance costs.
