In each family, there are 9 impeller sizes. The impeller sizes range from 550 up to 1780 mm. On the basis of the measured characteristics of the fan, the basic aerodynamic and strength characteristics have been calculated. The size category of the geometric parameters of the fan is based on the geometric progression and on the size of the chosen outer diameter of the fan’s impeller. All other dimensions which determine the geometry of the fan’s flow tract are proportionally co-dependent on the impeller size.

All other dimensions which determine the geometry of the fan’s flow tract are proportionally co-dependent on the impeller size. In the process of designing a fan, CFD software is used for the simulation of the fluid flow and heat transfer, with the help of which we set the dimensions and optimize the geometry of the fans. The shape of the impeller is adapted to the streamlines as much as possible during the design phase; by doing so, turbulences and by that local losses in the fan are decreased. Numerically, the flow capacity and pressure conditions in the fan are analyzed locally as well as integrally for each operational point of the fan. On the basis of such acquired data, it is possible - even with a computer simulation - to determine the characteristics of the fan, calculate its efficiency rate and perform a comparison incorporating the results of the experimental measurements. The necessary impeller power is also determined experimentally as well as a result of numerical modeling- i.e. as the product of the needed torque and rotational frequency.

The transported medium must not contain any toxic, chemically aggressive or explosive substances. If the concentration of non-sticking particles does not exceed 200 mg/m3, transportation is allowed; if it does, a fan with a special constructional base is manufactured according to the customer’s needs.
