Key Specifications of Perkins Air Filter S551/4
The Perkins SE551C/4 (also known as the SE551C4) is a heavy-duty, high-performance Power Core primary air filter engineered specifically to provide elite-tier filtration for demanding industrial diesel and marine engines. It is widely used in high-capacity generator sets and heavy construction machinery powered by robust engines like the Caterpillar C18, C27, C32, and C175 series.
Description
The Perkins SE551C/4 Air Filter utilizes advanced PowerCore filtration technology, featuring a distinctive honeycomb media design instead of conventional pleated paper. This structure allows straight-through airflow, which maximizes surface area coverage while minimizing space constraints. The result is a highly compact, lightweight profile capable of fitting tightly configured engine compartments without hindering airflow.
Operating in severe conditions exposes engines to fine dust, rust particles, and airborne contaminants. The SE551C/4 effectively eliminates 99% of particulate matter, ensuring only clean air reaches vital internal components like fuel injectors and turbochargers. By neutralizing these microscopic abrasives, the filter significantly minimizes component wear, optimizes combustion efficiency, and prevents early engine deterioration.
Structurally, the unit features rigid spiral glue binding to stabilize its inner media flutes, guaranteeing consistent filtration integrity even under extreme pressure changes. Its rugged design extends its operational service lifespan up to 2,000 hours (or 5,000 km depending on environmental applications), drastically dropping maintenance intervals and overhead costs. Furthermore, the eco-friendly materials ensure the discarded filter can be easily recycled.
