Specification: Single-sided centrifugal fans in compact scroll housings with forward curved blades and impeller diameters from 180 to 225 mm.
Attributes and special features: Optimal motor cooling and a compact construction achieved through integrating the three-phase asynchronous external rotor motor into the impeller. Very high pressure increases feasible by using 2-pole rotational speeds. Both 50 and 60 Hz variants available.
Applications: External motor ventilation, ventilation
