Maximum Engine Protection & High-Efficiency Oil Flow
Heavy-duty industrial diesel engines operate under extreme thermal and mechanical pressures. The Perkins Oil Filter SE111B is specifically engineered to handle high oil flow rates while maintaining exceptional particulate holding capacity. Featuring deep-pleated synthetic cellulose media, the Perkins Oil Filter SE111B captures harmful contaminants without causing restrictive oil pressure drops, guaranteeing immediate lubrication during cold start-ups and peak generator load demand.
To guard against dry starts, the filter incorporates a rubber anti-drain back valve that holds oil inside the filter canister when the engine is shut down. Upon restarting, instant oil pressure is delivered directly to the engine’s upper valvetrain and turbocharger bearings. Furthermore, the heavy-duty steel casing resists structural deformation and seal degradation, preventing oil leaks and ensuring complete compliance with manufacturer maintenance standards across commercial, healthcare, and industrial generator installations in Bangladesh.
- Uncompromised Engine Protection: The Perkins Oil Filter SE111B traps microscopic soot and metal shavings before they reach critical engine galleries.
- Instant Startup Lubrication: Built-in anti-drain back valve prevents oil draining back into the sump, ensuring immediate oil pressure upon engine ignition.
- Heavy-Duty Pressure Casing: Reinforced steel canister withstands high internal oil pressure surges without bulging or seal failure.
- Direct OEM Specification: Precision 1 1/2-16 UN thread and square sealing gasket guarantee a leak-free seal during routine maintenance cycles.
- Extended Engine Life: Reduces wear on expensive engine components, extending overhaul cycles and protecting power plant investments.
