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 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).
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).
The APRED-APRFD-APRGD series always has a specific ratio greater than 1.11.

Use : For suction of clean and dusty air. Double-stage fans of this type are characterized by high output, which saves a certain amount of electrical power; using special type fan impellers with reverse blades (negative).
It is used in pneumatic conveying, cement factories, mills, “pasta” factories, paint works (for quick-drying wool), ceramics factories (pneumatic cleaning of rooms) to give oxygen to polluted waters, chemistry, iron where very high pressure small and medium capacities are required. and in the metallurgical industries. Fluid temperature should be above 80 °C.
