Centrifugal low and medium-pressure fan. High efficiency impeller with special profile blades. Belt drive.
V = 700÷240.000 m3/h
Pt = 70÷900 kg/m2
Use: the centrifugal fans of this high efficiency series are suitable for drying plants tyres, transportation systems, fumes, suction systems, forced suction chimneys, transportation of granulated material and sawdust mixed with air, excluding filament material.
Their main feature is that of joining up the high output (deriving from the use of a fan wheel with reversed blades, special profile) with the suitability of transporting materials mixed with air. Besides, these fans are distinguished by a very flat curve of the absorbed power, such as to not overload the motor neither when working with free throats.
They are assembled in carpenter shops, mechanical industries, cement factories, ceramic factories, tanneries , foundries,in themolinary and chemical industries, and in all those applications where it is necessary to transport harmuful air with max. temperature of 90° C.
For temperatures of the transported fluid higher than 90°C up to 350°C a small heat stopping fan is splined to the shaft between support and scroll; besides the fan is painted with a special aluminium paint suitable for high temperatures.
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 = 64 (Reg. UE N.327/2011).
ErP calculations take into account efficiency IE3 motors conforming to IEC 60034-30.
