Centrifugal fan with forward curved blades in galvanised sheet metal
Extraction of air with a low 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 9005 black.
In the standard version, the electric extraction fan is in the B5 version and therefore with no seat or base, installed by means of holes present on the suction nozzle.
- Impellers: Employs forward curved impeller blades manufactured from galvanised 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.
