Venttek-high-efficiency axial fans are manufactured to a solid industrial design with welded steel impellers. Different drive types can be accommodated as well as complete fabrication in stainless steel. Where prevention of explosion is required it is possible to install a brass ring within the fan casing around the impeller. The included dimension table shows only a segment of the possibilities. Most special requirements can be accommodated through addition of appropriate components and specific construction measures, for example in aggressive mediums and flue gases, to provide a satisfactory solution. In such specific applications, please contact us with your special requirements. In all applications, horizontal as well as vertical installation is possible.

Two different series axial fans are produced. Namely the VL and NL series, the difference is in impeller design. By application of upstream guide vanes (VL) or downstream guide vanes (NL) we are able to satisfy a wide operating range. Changing the number of blades allows the adaptation to the desired operating parameter even where the motor speed is constant. This permits considerable flexibility in the fan casings.

This literature only documents characteristic curves of the VL6.L types; where the desired operating parameters can not be satisfied with the presented data, please contact us with your requirements.
