Functional all round

The Air series, to which airnovel belongs, consists of a permanent magnetic coupling and flanged air motor. The speed up to 1'750 rpm is read off an analogue tachometer and the regulation is infinitely variable via a fine adjustment valve. Airnovel is the uncomplicated laboratory partner in the Ex zone.
