MICROMASTER 4 (MM4): Substitute Fan for frame size F (FSF)
The ordered substitute Fan for MM4 FSF, does not match! What can I do?
The spare part fan is larger than the original assembled fan.
- This is caused by the different power ratings of the frame size F units. They vary between 30, 37, 45, 55 and 75 kW.
- To save costs we have only one spare part fan for all power ratings.
- The biggest fan is chosen as spare part for all frame size F units.
- To allow assembling of bigger fans at lower power ratings, the frame size F housings have extra drillings where needed.

The three drillings on the larger radius (90 mm) are for assembling a spare part fan.
The three drillings on the smaller radius (81 mm) are for assembling an original fan (only at the factory).
