Company statement frequency converter with axial fans 
Dear Sir or Madam, 
We hereby confirm that the use of a frequency converter for speed control of axial 
fans of the AXC series is permissible. 
The operating range of the fan should be limited to a minimum of 10 Hz and a 
maximum of 60 Hz (provided that 60 Hz is an available operating frequency in the 
axial selection software). The rated electrical motor data indicated on the motor type 
plate must not be exceeded. This applies in particular if the operating frequency 
exceeds the mains frequency. 
Furthermore, we confirm that the use of a frequency converter  
(tested type: Danfoss FC102) for speed control of axial smoke extract fans of the 
AXC (B) and AXC (F) series is permissible. The operating range of the fan should 
be limited to a minimum of 10Hz and a maximum of the mains frequency (see fan 
type plate). The rated electrical motor data indicated on the motor type plate must 
not be exceeded. If, in individual cases, the mains frequency is to be exceeded 
during operation, please contact Systemair in advance. 
The information in the installation and operating instructions of the used frequency 
converters and fans must always be observed. 
Please do not hesitate to contact us if you have any questions.
