2.2 Weight
The total weights shown in table 1 apply
to axial flow fan type ACN-smoke. The
total weight is determined on the basis of
type/size of fan and maximum motor

2.3 Transport
When transporting the fans take care
that no water (e. g. rainwater) gets into
the motor or other sensitive components.
Novax smoke exhaust fans type ACN-
smoke are delivered on pallets or bearers
to allow fork-lift transport.
The forks of the fork-lift truck must lift
underneath the frame. Set down the fan
as slowly as possible and on a soft foun-
dation. Vibrations, shocks, and fall may
result in imbalance and deformation and
may damage the motor bearings.
