Series U/ET
|
The U/ET series axial fans are designed to extract stale air, fumes and
vapours at temperatures of up to a maximum 50°C. They are used in all industrial plants where large volumes of air are to be removed without using pipes. The structure has an anchoring base and a waterproof roof made of steel sheet treated with special powders to protecting against the weather. The high performance die-cast aluminium alloy airfoil impellers have been perfectly balanced and are connected directly to the motor shaft. In models Ø 710 and higher the impeller blade inclination can be adjusted when the fan is off. Normal airflow from motor to impeller can always be inverted by simply inverting the motor rotation, dismantling the impeller and reinstalling it upside down. The motors installed are asynchronous, three-phase or single-phase, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant. ACCESSORIES
