Low-noise fan EU Series

centrifugalsuctionfor chemical applications

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° C with cooling fan. For higher temperatures it is necessary to make some changes on the construction of the fan. ErP: these fans are covered by Directive 2009/125/EC. This law does not apply in the following cases: - Operation in potentially explosive atmospheres (ATEX) - Operation with high temperatures (fans designed with cooling fan) - Operation with temperatures below -40°C - Working in toxic, corrosive or abrasive enviroments (use of material such as AISI 304, AISI 316, manganese steels). These series are centrifugal backward curved fans and therefore expected Ntarget = 61 (Reg. UE N.327/2011). ErP calculations take into account efficiency IE2 motors conforming to IEC 60034-30.
