NEW: centrifugal fan by MORO

Operating range: High fl ow 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 fan 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 defi ned 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. RLD fans are constructed with the “classic” spiral shape.

Operating conditions: Conditions of inlet air T=20°C, pb=760mmHg

Noise levels: The noise levels are established with measurements taken at

the 4 cardinal points, at a distance of 1.5 m from the fan.

Orientations: The RLD series fans up to size 800 off er 8 orientation positions

(4 clockwise RD and 4 anticlockwise LG), from size 900 and above they off er 16

orientation positions (8 clockwise RD and 8 anticlockwise LG) when viewing

the fan from the transmission side.

Special arrangements: Anticorrosive version: painted or made in special

materials (stainless steel).
