Axial impellers C-system Thanks to many years of experience in developing and manufacturing impellers for the Multifan fans, Vostermans Ventilation has obtained a thorough knowledge of everything related to axial impellers. It is obvious that one of the most important fan components - the impeller - is paid full attention to. As a result, Multifan impellers are of the highest quality and are employed in a wide range of applications. C-system The blade root is ex factory provided with a root with 2 flat sides and has thus a fixed blade root (25 t/m 45°). This means that the customer cannot change the angle. This system is available for blade types 2, 3 and 5. The C-system is mainly used for smaller fans and/or lower speeds. The advantage of the system is the easy assembly of the impellers. The blades are available in any diameter. Blade profiles Type 2 Small and slim profile for the smaller diameters from 200 to 450 mm. This profile is mainly used for 1400 RPM and 2800 RPM motors. Due to a flat outer curve the range of application is broad. This type is available in different materials. It is also available in clockwise and counter-clockwise turning version. Type 3 The most-sold profile for applications with diameters from 200 to 710 mm. This blade type is mainly used for 1400 RPM units but also provides excellent properties at 900 RPM. Thanks to its properties and good values with regard to pressure and efficiency, the range of application is very broad. Type 3 is available in different materials. It is also available in clockwise and counter-clockwise turning version. Type 5 This blade type was specially developed for diameters from 300 to 710 mm. Type 5 is mainly used for 900 RPM and 1400 RPM. Its strong points are a high pressure build-up and good efficiency. In the 900 RPM range its low noise level is to be pointed out. The blade is available in different materials. This type is only available in counter-clockwise turning version.
