Fan Sizing Program

Our online fan sizing software “ColaVent” is directly focused on the specific needs of designers and engineers.

The fast-line mode can be used immediately without registration. After entering the operating data (flow rate and static pressure) and the preferred type of drive, you will directly receive a selection of suitable fans with corresponding characteristic curves for your application. Within the selection you filter according to further criteria such as efficiency.

The expert mode is available for free after one-time registration and offers extended functions.  You can already select the required plastic material, any necessary explosion protection and efficiency requirements for the motor.

In addition to the complete fan design, the automatic generation of the tender text in Word format is also available. All data selected during the fan design process, such as operating point, materials, type of drive, motor data and ATEX zone classification, will be adopted.

With one click you can send us an online request for quotation of your configured fan. You will receive the corresponding offer within a very short time.
