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.
Please note that these fans are designed to carry material. For this reason, Directive 2009/125/CE applies, but is not subject to the energy efficiency restrictions it imposes and thus the verification of these parameters.

Use : High output centrifugal fans of this series, excluding filament material It is generally suitable for absorbing dust, fumes, granules, saw or wood shaving of minimum size and materials mixed with air.
Its main features are the combination of high efficiency (obtained from the use of a reverse-bladed fan wheel, special profile) with suitability for the transport of air-mixed materials. Also, these fans are distinguished by a very flat curve of the power absorbed, as when operating with free throttles the motor is not overloaded.
In carpentry workshops, mechanical industries, cement factories, ceramic factories, tanneries, foundries, mining and chemical industries and harmful air max. It is used for absorption at a temperature of 90 ° C.
