Duct-S ducted compact axial fan

Duct-S line is designed for large air capacities with low pressures, in duct mounted applications. For instance: ventilation of industrial plants, car parks, stock farms, cooling of electric and refrigerating equipments, in industrial or marine sectors.

This line consists of 8 sizes with impeller diameter from 300 up to 700 mm.

The main characteristic of Duct-S fans is the extreme compactness, due to the reduced dimensions of the motor-impeller assembly; therefore with dimensions lower than the traditional short cased axial fans with IEC motor we avoid the motor to protrude from the rear flange, with the consequent possibility of installation in both the extremities and the middle of the ducts. Another peculiarity is the perfect regulation of the speed, without producing noise (electric hums) or abnormal consumption of current.

Casing in steel sheet protected with epoxy paint; fixing flanges according to UNI EN ISO 13351 / Tab.1.
Impeller with high efficiency airfoil blades in plastic material and hub in die-cast aluminum alloy, variable pitch angle in still position; balancing according to UNI ISO 21940-11.
Asynchronous electric motor three or single phase with thermal protection speed adjustable, protection IP 55, Class F insulated, service S1.
Arrangement 5 (impeller directly coupled to motor shaft).

Accessories: Flat protection grid (FPG-DU) necessary for use in free air - Fixing feet (FF-DU) - Inlet nozzle (IN) - Flexible connection (FC-DU) - Antivibration mounts (AM) - Counter flange (CF-DU) - Silencers (SIL-DU) - Speed regulators (SR) - Service switch (SW).

On request: Versions with die-cast aluminum blades - Versions with air flow from impeller to motor, position B (FGM).
