In mining and heavy construction, the engine is the heart of the equipment, and the lubrication system is its lifeblood. Impurities and wear are the number one killers of engine life. The 1R-1808 Oil Filter acts as a dedicated "kidney" for your machinery. Utilizing high-quality wood pulp filter paper formed through a specialized folding process, assembled within a cold-rolled steel yellow spray-painted shell with an oil-resistant rubber gasket, this filter is designed for diesel engines in mining drill rigs and engineering machinery. It aims to provide high filtration efficiency and maximum dust-holding capacity, ensuring every drop of oil remains pure to protect critical moving parts like crankshafts and bearings from wear.
The filter media is the soul of the cartridge. We reject recycled paper or low-quality fibers, insisting on import-grade, fully resin-impregnated wood pulp filter paper:
Deep Pleat Technology: Advanced pleating machines create dense, corrugated structures. This design maximizes the filtration area within the limited canister space, reducing flow resistance while drastically increasing Dirt Holding Capacity and extending service intervals.
High-Efficiency Filtration: The paper fibers are cured with special resin, creating uniform and fine pores. It effectively captures harmful particles larger than 20-40 microns, including metal debris (iron/copper shavings), carbon deposits, colloidal matter, and combustion soot.
Wet Strength & Anti-Aging: Treated for oil, water, and corrosion resistance, the paper maintains structural integrity even after prolonged immersion in high-temperature oil, preventing softening, disintegration, or clogging.
The housing must not only contain the media but also withstand oil system pulse pressure and vibration:
Cold-Rolled Steel Construction: Made from high-quality low-carbon cold-rolled steel via deep drawing technology. Compared to cast iron or inferior plates, cold-rolled steel offers superior surface hardness and impact resistance, defending against physical shocks from rough terrain.
Yellow Anti-Corrosion Coating: The shell undergoes phosphating treatment followed by yellow industrial protective paint. This not only provides a distinctive brand identity but also forms a rust-proof and anti-corrosion armor, preventing perforation in wet, muddy environments.
Pressure & Burst Resistance: Engineered to withstand instantaneous oil pulse pressures during engine startup and sustained high oil pressure, ensuring seal integrity without risk of rupture.
Oil-Resistant Rubber Gasket: The sealing ring is made of special Nitrile Rubber or Fluoroelastomer , offering excellent oil resistance, heat resistance, and resilience. It maintains a tight fit across extreme oil temperatures , eliminating the common plague of oil leakage.
Intelligent Bypass Valve: Equipped with a high-precision spring-loaded bypass valve. If the filter becomes clogged due to overdue maintenance or high oil viscosity in cold weather, the valve automatically opens to ensure oil continues flowing to the engine, preventing seizure .
Anti-Drain Back Valve: Some models feature an anti-drain back valve, keeping the filter full of oil after shutdown. This ensures immediate lubrication upon the next startup, minimizing cold-start wear.
This filter is built for high-load, high-dust environments:
Mining Drills & Crushing Equipment: Withstands severe engine vibration during rock drilling and ore crushing.
Construction Machinery: Suitable for diesel engines in excavators, bulldozers, loaders, etc.
Multi-Brand Compatibility: Manufactured strictly according to 1R-1808 original drawings, perfectly fitting various heavy-duty diesel engines.
Prevents Bearing Wear: Micro-metal particles act as abrasives between the crankshaft journal and bearings. Our filter is the first line of defense against catastrophic "spun bearing" failures.
Maintains Oil Cleanliness: Adsorbs acidic oxides and colloids, delaying oil degradation and extending drain intervals, thereby lowering operating costs.
Enhances Cooling Efficiency: Clean oil flows better, helping transfer engine heat back to the oil pan more effectively.
