توضیحات:
for the suction of clean and dusty air. These types of fans with doubles stage, are characterized by a high out put which allows a certain saving of electric power; by using special types of fan wheels with inverted blades (negative).
They are used for giving oxygen to impure waters, for pneumatic conveyalces, in cement factories, in the mills, in “pasta” factories, in dye works (for the quick drying wool), in ceramic factories (for the pneumatic cleaning of the rooms), in chemical, iron and metallurgical industries where small and medium capacities with very high pressure are required.
The temperature of the fluid sucked in must not exceed 80°C.
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 with high temperatures (fans designed with cooling fan)
– Operation with temperatures below -40°C
– Working in toxic, corrosive or abrasive enviroments (use of material such as AISI 304, AISI 316, manganese steels).
Please note that in the case of specific ratio >1,11 the Directive 2009/125/CE is applied, but these fans are not subject to the constraints of energy efficiency that it impose and therefore neither to the verification of these parameters.).
Series APRED-APRFD-APRGD always have a specific ratio greater than 1.11.
