Speed controllable fans: “Measured data at commissioning” at maximum speed
3. Switch the fan off.
9.2 Commissioning of speed-controlled fans
Check the fan for vibrations at all normal operation speeds during commissioning. Determine and evaluate vibrations
on the housing and bearing areas in accordance with DIN ISO 14694 depending on motor power and positioning.
Measurable vibration velocities depend e.g. on following factors:
• positioning
• bottom section/foundation state • flow conditions
The working point of the fan, as well as used external devices and accessories, also influence the running
characteristics.
9.3 Adjusting the blade angle
If the working point of the fan has to be changed and it is necessary to adjust the blade angle, please contact
Systemair!
