Centrifugal fan RC

suctionsteelIP55

Centrifugal fans with backward curved blades in thick steel sheet metal Extraction of air with a high volumes of particulate, exhaust gases, welding fumes, etc. - Structure: The structure of the extraction fan is entirely manufactured from welded steel sheet metal of a suitable thickness which is then epoxy coated in RAL 7032 grey. In addition to the support base for the electric motor, an additional seat can be requested secured to the suction nozzle to increase stability of the machine. - Impellers: Employs epoxy coated backward curved impeller blades manufactured from thick galvanised, welded sheet metal, static and dynamic balancing according to ISO standards, keeping noise and vibration levels to a minimum. - Motors: Three-phase asynchronous IE2 efficiency, normally 400V/50-60Hz IP55, in accordance with UNELMEC standards. Installed with 2, 4 or 6 poles depending on the required pressure, or with dual-polarity for two-speed versions. It is designed to be assembled on a support base shared with the fan. The power indicated in the performance tables have been sized taking into consideration machine performance and an additional safety margin to compensate for any system faults. - Special versions: ATEX for environments with a risk of explosion regulated by Directive 94/9/EC.
