Fan wheel setting
N6/N7/N8/N9 - EKEVO 6/EKEVO 7.3600/EKEVO 8/EKEVO 9
The fan wheel can be stopped at any
position on the motor shaft.
To achieve a high slipping torque, the
surface of all the parts to be inserted into
one another must be clean and grease-
free.
Removing the fan wheel
Note:
Before removing the fan wheel, a
mark must be made on the shaft in
order to ensure that the wheel is in
the same position after reinstallation.
If the wheel position on the shaft is
changed axially, efficiency may be
reduced and this could result in
reduced air output.
To remove the wheels, undo the screws
(items 1 and 2); screw one of them into
the hole in the bushing to half a thread
fitting (item 3) as a lever screw and pull.
This loosens the bushing. The loosened
disc unit can now be removed by hand
without force and without causing
damage.

Important: The air conveyor must be positioned in relation to the
blower turbine so that a gap (S) of a constant size is achieved
around its entire circumference.

Fan wheel installation
- Clean all the bare surfaces and
degrease them
- Insert the discs and bushings into one
another, align the holes.
- Align the screws on opposite sides
(items 1 and 2) and tighten them
evenly.

must be observed:
SM 16, bushing no. 1615 - hub bore 28 :
Tightening torque 20 Nm
SM 20, bushing no. 2012 - hub bore 38
and 42 mm:
Tightening torque 30 Nm
SM 25, bushing no. 2517 - hub bore 42
and 48 mm:
Tightening torque: 50 Nm
