Atlas Copco 2903752501 Oil Filter Air Compressor Spare Parts

Atlas Copco genuine 2903752501 spin-on oil filters deliver precision lubricant purification and hydrodynamic bearing protection for industrial oil-injected rotary screw air compressors. Cataloged under part number 2903 7525 01 and directly interchangeable with factory reference 1625752501, this component removes solid particulate contaminants from circulating oil before it is reinjected into the compression element.
In oil-injected screw compressors, the lubricating fluid performs three critical functions: removing thermodynamic compression heat, sealing rotor profile clearances, and forming a continuous protective film on precision roller bearings. Allowing particulate-laden or oxidized oil to circulate through the machine causes abrasive micro-scoring across male and female rotor flanks and accelerates fatigue spalling on high-speed bearing raceways.

• High-density pleated media: Synthetic and cellulose composite construction traps sub-micron metal wear fragments, atmospheric dust, and carbon varnish particles without causing excessive hydraulic pressure drop.
• Heavy-duty spun steel canister: Pressure-tested to withstand continuous operational vibration, thermal expansion cycles, and severe hydraulic pressure pulsations during rapid load-to-unload transitions.
• Integrated internal bypass valve: Calibrated to open automatically under high differential pressure conditions, ensuring uninterrupted oil flow to critical bearing surfaces during cold morning startups.
• Perforated steel center core: Provides structural rigidity against pressure differential collapse, maintaining uniform pleat spacing and preventing filter media pinching under high contaminant loading.
• Pre-fitted high-temperature elastomer gasket: Ensures a dependable leak-free seal against the compressor filter mounting manifold, eliminating hot lubricant weeping in severe industrial operating environments.
• Factory-sealed packaging: Every genuine filter is individually boxed and consolidated in export-grade cartons on wooden pallets for damage-free international transport.
