Radial fans



running wheel A
running wheel B
running wheel C



The radial fans are installed either before or after the filtration system (overpressure or vacuum system). Depending on the use, different running wheels are implemented:


  • closed running wheels with bent back blades -
    Running wheel A for feeding purified air, air with shavings or dusts (short-fiber shavings) with a low material content,



  • closed running wheels with backward blades -
    Running wheel B for feeding air with material content (dusts or shavings - medium material content),



  • open running wheels radially bladed -
    Running wheel C for feeding air with material content (coarse, long-fiber shavings and wood ships - high material content).


Running wheels with different diameter ratios are used depending on the total pressure requirement. 


Standard fans

Sizes / capacity range


Up to a nominal size of 400, standard fans are available with different running wheel equipment for different pressure levels. The casings and running wheels on these fans are manufactured in large series and can be assembled and delivered on short notice as needed. Due to the se-rial production, an especially low-cost price-to-value ratio is achieved. Depending on the nominal size, the running wheels used and the pressure level, motors with capacities between 2.2 kW and 18.5 kW are used. These are generally direct drives in which the running wheel is directly mounted on the motor shaft. 

The fans are delivered complete with suction and pressure side joints including mounting rails. 

For standard fans, the complete accessory program (see Designs section) is available.
