Multifunctional fan box, suitable for medium to higher air flow volumes against high resistances in every type of ventilation system. The compact frame construction offers easy conversion of the outlet position, together with a choice of ideal accessories make these units ideal for all applications.
Casing
Self-supporting frame construction made from hollow aluminium profiles. Lined with 20 mm thick double-walled side panels made from galvanised sheet steel, sound and thermally insulated with flame-retardant mineral wool. Intake cone for ideal airflow, spigot and flexible connector for duct connection. With discharge adapter (from square to circular) on the pressure side for low-loss discharge and flexible sleeve to reduce vibration transmission. Simple positioning with standard crane hooks.Impeller
Free-running high-performance centrifugal fan made from steel with backward curved blades on a galvanised steel plate, direct driven. Energy efficient with low noise development. Dynamically balanced together with the motor according to DIN ISO 1940 T.1 – grade 6.3.
Through maintenance-free, speed controllable external rotor motor protected to IP 44. Ball bearing mounted, interference-free.
Electrical connection
Standard terminal box (IP 54) on motor.
Motor protection
Through built-in thermal contacts wired in series with the winding, switches off and on automatically after cooling.
Speed control
Through voltage reduction by means of 5-step transformer or electronic speed controller. The performance stages are specified in the performance curve.
