High efficiency and low-noise reverse-blade impeller.

Directly coupled motor.

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.

The temperature of the fluid sucked in must not exceed 80°C and 150° with cooling fan.


Characteristics:    V = 380÷5.400 m3/h      |      Pt = 150÷500 kg/m2

ErP: these fans are covered by Directive 2009/125/EC

A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine.

I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents. I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now.

When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary, I throw myself down among the tall grass by the trickling stream; and, as I lie close to the earth, a thousand unknown plants are noticed by me: when I hear the buzz of the little world among the stalks, and grow familiar with the countless indescribable forms of the insects and flies, then I feel the presence of the Almighty, who formed us in his own image.
