SEV551F/4 Air Filter – Replacement Element for Perkins & FG Wilson Generators

The SEV551F/4 air filter is designed for Perkins and FG Wilson 400 kW generator sets. Built with a reinforced outer mesh and premium pleated media, it effectively removes dust and particles from the intake system, ensuring the engine runs clean and efficiently.

From field experience, SEV551F/4 is widely used in medium-size diesel gensets where consistent airflow and strong dust-holding capacity are essential. Its precise dimensions allow easy installation, while the durable sealing prevents leaks that could lead to costly engine wear.

By replacing the SEV551F/4 filter on schedule, operators can extend engine service life, reduce maintenance costs, and avoid unexpected downtime.
