VDN-type fan is primarily a forced-draft pressure fan (hence its designation — VDN).
In essence, it is a centrifugal draft fan with single-sided air intake, made of carbon steel. Due to its design characteristics, this machine is primarily a fan and not a smoke exhauster.
The VDN-type fan is intended for moving air and explosion-proof, non-aggressive air-gas mixtures with temperatures from -30 °C to +80 °C, with dust content up to 0.1 g/m³, and without sticky, fibrous, or abrasive particles.
Equipped with a backward-curved blade impeller — to increase efficiency, reduce noise, and save energy.
