The temperature of the fluid should be above 80 °C and 150 °C with the cooling fan as sucked. For higher temperatures it is necessary to make some changes in the structure of the fan.
ErP : These fans are within the scope of Directive 2009/125 / EC. This law does not apply in the following cases:
- Operation in potentially explosive atmospheres (ATEX)
- Operation at high temperatures (fans designed with cooling fan)
- Operation at temperatures below -40 °C
- Working in toxic, corrosive or corrosive environments (use of materials such as AISI 304, AISI 316, manganese steels).
These series are centrifugal backward curved fans and therefore Ntarget = 61 is expected (Reg. UE N.327 / 2011).
Efficiency IE2 motors conforming to IEC 60034-30 are taken into account in ErP calculations.

Use : For absorbing very dusty air containing various types of material in suspension. The main feature of such fans is the high output relationship (due to the special profile resulting from the use of a reverse blade rotor) with the suction of dusty fluids or those containing granular materials.
Also these fans are characterized by a very flat curve of the absorbed power so that the motor is not overloaded when running with open inlets.
They are installed in joinery to transport saw dust and wood shavigs, excluding filamentous material, in mechanical industries to absorb metal chips, pneumatic conveying of cement plants, ceramic plants, mills, feed mills, tanneries, foundries, textile and chemical. Industries where it is necessary to transport harmful air at low and medium pressure, and in all these applications in general.
