The fan casing is made of galvanised steel and provides reliable protection against corrosion. All sizes of Kanal-VENT-N-SH are provided with a cover for service of the impeller and motor during installation or maintenance of the fan.
The noise-insulated casing distinguishes Kanal-VENT-N-SH from the standard series. The casing is made of galvanised steel and is a box construction. The space between the walls of the noise-insulated casing is filled with fire-resistant wool with high sound insulation properties.
Operating wheels of duct fans with backward curved blades are made of aluminium steel and undergo thorough static and dynamic balancing.
Canal-VENT-N-S, in contrast to the fans of the standard series with forward-curved blades, have a higher efficiency, providing energy savings. In addition, Canal-VENT-N-SH fans create less noise during operation, providing a more "quiet" operation of the system.
