Pneumatic semi-rotary drives with vanes are characterised by their compact design. The energy of the compressed air is directly converted into a rotary movement by the vane. Rotary vane drives therefore do not require an additional transmission ratio. That is why the compact and lightweight design is a great advantage. Rotary vane drives easily achieve a swivel angle of 270°.
