Engine and machine filtration
Engine air filtration
Primary and secondary intake elements for engines, compressors and mobile units.
The primary element stops the bulk of intake dust; the secondary element protects the engine while the primary is serviced. Airflow, dust holding capacity and seal integrity govern the choice.
Air path and clogging
- Intake air — the drawn air enters the filter body, carrying ambient dust.
- Retention — particles stay on the upstream face of the primary element, which stops the bulk of the load.
- Secondary — the second element sits across the outlet. It does not replace the primary: it holds the line while the primary is removed.
- Filtered air — the air leaves through the body outlet, on its way to the engine.
The secondary stays in place when the primary is removed: it is during that removal that it protects the engine.
