Venti Oelde has developed shock resistant and flame-proof rotary airlocks. They are suitable for large, high-volume quantities of materials such as, for instance, arise when conveying MDF fibres. The airlock has flexible sealing strips. This ensures that explosions or fires are decoupled – for example, between filter systems or separators and the next part of the conveyor system.

The rotary airlocks have been tested and certified to ATEX guidelines 94/9/EU, and may be used as protective systems in areas at risk of explosions.
