Fit and Forget Engine Protection
The Eurocopter EC135 is the helicopter of choice for police and Emergency Medical Services (EMS).

Maintenance
The PUREair is a “fit-and-forget“ system; there are no inlet barrier filters to replace or clean. As with all aircraft equipment, routine visual inspection is recommended.The Pall PUREair solution is an environmentally friendly alternative to oil-wetted barrier filters. There is no filter replacement and no daily cleaning as with oil-based solutions that are difficult and costly to dispose of. |
