MEDIUM PRESSURE CENTRIFUGAL FAN – HIGT EFFICIENTLY AND LOW NOISE RESERVE BLADE IMPELLER – DIRECTLY COUPLED MOTOR
EU V =380 ÷ 70.000 m3/h Pt = 45 ÷ 550 kg/m2
Use: for sucking in very dusty air containing various types of materials in suspension.
The main feature of these types of fans is the association of high output (deriving from the use of a rotor with reversed blades, special profile), with the suction of dusty fluids or those containing granular materials.
Besides these fans are characterized by a very flat curve of the absorbed power, in order not to overload the motor neither when working with open inlets.They are assembled in joineries for transporting saw dust and wooden shavigs, excluding filamentaus material, in mechanical industries for sucking in metal chips, in pneumatic transport of the cement factories, ceramic factories, mills, fodder factories, tanneries, founderies, in textil and chemical Industries and in general in all those apllications where it is necessary to transport harmful air with low and medium pressure.

LOW pressure centrifugal fan – Impeller with blades curved forward – Directly coupled motor
BP V=180 ÷ 20.100 m3/h Pt = 15 ÷ 220 kg/m2
Use: for the removal of clean or slightly dusty air.
They have high efficiency and reduced noise level, the fans of this series are largely used, inventilation, conditioning, drying, cooling, mechnical draft, and toxic gas elimination plants. The temperature of the fluid transported must not exceed 80°C without cooling fan and 150° C with cooling fan. For higher temperatures it is necessary to modify the construction of the fan.
