A small heat-stop fan is threaded on the shaft between the support and the spiral for temperatures of the transported liquid from 90°C to higher than 350°C; In addition, the fan is painted with special aluminum paint suitable for high temperatures.
ErP : These fans are within the scope of Directive 2009/125 / EC. This law does not apply in the following cases:
- Working 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 : Centrifugal fans of this high efficiency series, excluding filament material It is suitable for transporting plant tires, transport systems, fumes, suction systems, pressure suction shafts, granular material and sawdust mixed with air.
Its main features are the combination of high efficiency (special profile resulting from the use of a reverse bladed fan wheel) with suitability for handling air-mixed materials. Also, these fans are distinguished by a very flat curve of the absorbed power, such that the motor is not overloaded when running with free throats.
In carpentry workshops, mechanical industries, cement factories, ceramic factories, tanneries, foundries, mining and chemical industries and harmful air max. It can be used easily in transportation at temperatures of 90 ° C.
