Abstract

The suction blower has at least two radial fans (3,3a,3b) with flywheels and connected together through a flow channel (8). The radial fans are mounted off-set relative to each other on separate drive shafts (4, 4a, 4b) so that the flow deflection is less than 180 degrees in the flow channel between the outlet opening (6a) of the first and the intake opening (7a) of the second fan. The drive shafts can be mounted floating at their ends mounted in the radial fans but each individual drive shaft does not project over the end side of the flywheel facing the intake opening.
