Rotary vane 

The conversion from a fleece filter bag to PE bags requires different air conditions in the container. This is easy to set by simply moving the rotary vane right or left. The filling volume when a fleece filter bag is used is 14 litres. The filter cartridges are not activated as a result of the closed system. When using a PE bag, the filters are cleaned as required. The filling volume is significantly higher at 25 litres.
