Abstract (en)
[origin: EP0823555A1] The centrifugal ventilator (1) has an outlet (20) and at least two intakes (2,3) situated on either side of a rotor (4) powered by a drive. Each intake has a regulating system (30) designed to create an asymmetrical intake flow for operating the ventilator in a partial mode. The regulating systems differ in their mechanical structure and their degree of fine or coarse control. One regulating system is in the form of a shutter and the other has one or more louvres.
