ColaVent goes online

Our ColaVent® online design program for fans is directly geared to the specific needs of planners and engineers. Two versions of the program are available: Fastline and Expert.

Fastline can be used immediately without registration. Just enter your operating data (volume flow and static pressure) and the preferred drive type, and you will immediately receive a selection of suitable fans with the relevant characteristic curves for your application. You can filter the selection using additional criteria such as efficiency, and send your quotation request to us in just a few steps.

In addition to the complete fan design and tender texts can also be automatically generated in Word. All data selected during the fan design stage, such as operating point, materials, drive type, motor data and ATEX zone classification, are transferred across.

Expert is available free of charge after a one-off registration and offers even more detailed search functions. This includes entering the preferred plastic, any required explosion protection,  and efficiency requirements for the motor. Expert mode also allows you to send us a quote request for the fan you have configured online with a single click. You will receive the relevant quotation in no time at all.

The Colasit fan design program is easy to use and provides a direct link to the Colasit homepage.
