Directly controlled by a semi-elastic joint, this series has been realized with the aim of maintaining maximum rigidity and keeping noise very low. The connection of the fan and the motor with the joint eliminates the axial and radial stress on the motor supports, providing a long working life for the motor.
The temperature of the fluid is 90 ° C. With the cooling fan on the support, max. 350°C.
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.
special rate> In the case of 1.11, please note that Directive 2009/125 / CE applies, but these fans are not subject to the energy efficiency restrictions imposed and thus the verification of these parameters.

Use : For suction of clean and dusty air. Such high-pressure fans are characterized by a high output, which saves electrical energy, as they have a special fan impeller mounted with reverse blades (negative).
This type of fans is partially suitable for air supplies requiring medium and high pressure in pneumatic conveyances, cement plants, foundries, mills, “pasta” factories, chemical, metallurgical and iron industries.
