Abstract
This centrifuge includes a chamber (5), a rotor (6) arranged therein, and a device (8) for driving the rotation of the rotor. The device (8) for driving the rotation of the rotor is a pneumatic drive device. The centrifuge includes a circuit for supplying the pneumatic drive device with pressurized gas intended to be connected to a source (49) of pressurized gas. The centrifuge further includes a gas-purification unit (10), one inlet of this unit being connected to an outlet (64) for drawing gas from the chamber and one outlet of this unit being connected to a suction device (21) controlled by the pressurized gas supplied to the pneumatic device (8) for driving the rotor. Application is to the centrifuging of products liable to release dangerous substances, for example toxic or explosive substances.
