dynamically balanced. For other materials see pgs. 1.12 to 1.15.
Operating specifi cations: Condition of inlet air T=20°C, 0 m above sea
level and ρ=1.205 kg/m3
.
Noise level: Expressed as sound power LwA [dB(A)] measured in free fi eld
with ducted fan, see pgs. 1.43 to 1.49.
Orientations: No.8 RD (clockwise viewed from transmission side) and No.8
LG. Fan in bolted orientable version for sizes 500-630, with front support and
so not orientable for sizes 710 and above with transmission drive, always
orientable for directly coupled fans without front support. See pg. 2.7.
Special applications: See pgs. 2.20 to 2.30.
Fan start-up: The VC/P series fans must be started-up with inlet completely
closed. Check the electrical motor manufacturer’s data for the eff ective
number of start-ups per hour that the motor is able to sustain; unless
otherwise indicated take one start-up per hour to be the maximum.
If it is necessary to start up the fan more frequently and this can be achieved
by installing a larger motor.
