Fuel filter
SEPAR SWK switchover system
The SWK filter series for diesel fuels reliably removes water and dirt particles from the fuel, thus protecting engines from wear, failures, and costly repairs.
The special multi-stage filtration principle is identical in all sizes and impresses with its compact design and high flow rate.
The redundant design guarantees maximum operational safety. Even during a filter change, engine protection remains active, effectively preventing downtime.
