The fan casing is made of galvanised steel and provides reliable protection against corrosion. All sizes of Kanal-PKV-N-Sh(-RC) are provided with a cover for service of the impeller and motor during installation or maintenance of the fan.
Noise-insulated casing distinguishes Kanal-PKV-N-Sh(-RC) 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 non-flammable wool, which is characterised by high sound insulation properties. The impellers of duct fans with backward curved blades are made of special polymer and undergo careful static and dynamic balancing.
Canal-PKV-N-SH(-RC), unlike fans of standard series with blades bent forwards, have higher efficiency, providing energy saving. In addition, fans Kanal-PKV-N-SH(-RC) when working create less noise, providing a more "quiet" operation of the system.
