Activated by a pneumatic pulsator, the AIR driving units are used to generate the advancement of the parts inside a channel or a bowl in environments where there is a risk of fire or explosion, both due to gas or powders. They require a regulator to stabilise the air pressure and a flow regulator to adjust speed. The air supply pressure must be of at least 4.5/5 bar and the flow must be sufficient to ensure the correct operation of the equipment
