NEW: centrifugal fan by MORO

Field of operation: Medium-low fl ow rates. High pressures.

Blade type: Curve, backward (negative), see pg. 2.2.

Applications: For pneumatic transport, dust, drying, pressurization. Suitable

for applications in industrial fi elds like foundries, pasta factories, bakeries,

chemicals.

Standard constructional arrangements: Arr.1 - Arr.4 - Arr.5 - Arr.8 -

Arr.9 - Arr.12, see pgs. 2.5 - 2.6.

Standard fl uid temperatures: -10÷+60°C. For other temperatures see

pgs. 1.12 to 1.15.

Type of construction: Fan in Fe360 plate, impeller in Fe360 statically and

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 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.
