Specification: Single inlet centrifugal fans in standard scroll housings with backward curved blades. Impeller diameters from 225 to 315 mm are available, resulting in air volumes up to 2,400 m³/h.
Attributes and special features: Optimal motor cooling and a compact construction achieved through integrating the voltage controllable external rotor motor into the impeller. Pressure increases of up to 1,100 Pa are feasible by using the 2-pole voltage-controllable external rotor motors.
