MN (Backward Curve Direct Drive)

Medium-pressure centrifugal fan. High efficiency and low-noise reverse-blade impeller. Directly coupled motor air flow : 6-800 m 3 /min pressure : 55-530 mmWG 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
