Pneumatic rotary vane drives can easily achieve a swivel angle of 270° and are characterised by their extremely compact design. The energy of the compressed air is directly converted into a rotary movement by the vane, which is why rotary drives with vanes do not require an additional gear ratio. That is why the design is very advantageous, not just because it is compact but also because it is lightweight.
