VA centrifugal fans

The VA series fans are used for applications on the machine that require medium pressures. They are suitable for pneumatic transport, burners and in general for all applications where it is necessary to move very dusty air containing also sawdust, shavings, granular and filamentary materials through suction or delivery ducts.The auger is made of sheet steel with edged and welded profiles, provided on the delivery side with a fixing flange, drilling to allow a 45-degree orientation, nozzle on the suction side with fitting; the motor holder disc allows assembly reversibility. The orientation can be clockwise RD or counterclockwise LG (see table of orientations).The impeller with radial blades, made of carbon steel welded and balanced both statically and dynamically in direct coupling with three-phase or single-phase 2-pole asynchronous motors in construction form B5 or B3 and in continuous service S1 according to UNEL-MEC and IEC standards.The air temperature cannot exceed 90 ° C, this limit can only be exceeded in the special execution.
