Centrifugal fan / extraction / double-inlet / low-pressure

Operating range: High flow rates, low discharge heads.
Blade type: Backward.
Applications: Inlet of clean or slightly dusty air, when a very large air
capacity is involved with a low discharge head. They are used mainly in
systems:
for air conditioning; for drying ceramics, brickwork, etc; for airing silos,
storage areas, warehouses; extraction from indoor areas, solvent baths, spray
painting booths, etc.
Fluid temperature: Up to 60'C in standard arrangements; special
arrangements for higher temperatures.
Constructional characteristics: Robust construction in painted plate
metal, steel (an statically and dynamically balanced. These fans can be made
in three constructional classes (1-2-3) depending on the peripheral speed
limits of the impeller: the operating ranges of the 3 classes are defined in
table.
Fans up to size 800 are realized in Q form: the back of the fan case is welded to
two sides made from squared rather than spiral plate sections. Above this size
the Mod. PRD fans are constructed with the "classic" spiral shape.
Operating conditions: Conditions of inlet air T=2(TC, pb=760mmHg
Noise levels: Expressed as sound power LwA (dB(A)J measured in free field
with ducted fan, see pgs. 1.43 to 1.49.
