Centrifugal low and medium-pressure fan. Impeller with open blades. Special design for heavy-duty jobs. Belt drive.
V = 4.000÷130.000 m3/h
Pt = 135÷500 kg/m2
Use: the centrifugal fans of this series are suitable for the suction of wooden shavings, paper offcuts and filament material in general.
The wheel has radial blades and it is open.
The curve of the absorbed power increases to the free throat and it is suggested to choose a motor with 25% power in addition, in order to rectify errors, ifi any, in valuation of circuit leaks.
They are assembled in carpenter shops, tanneries, paper, factories, bookbinderies and in all those applications where a normal wheel can be easily obstructed.
ErP: 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).
These series are centrifugal forward curved fans and therefore expected Ntarget = 42 (Reg. UE N.327/2011).
ErP calculations take into account efficiency IE2 motors conforming to IEC 60034-30.
Please note that these fans are designed for transporting material. For this reason the Directive 2009/125/CE is applied, but they are not subject to the constraints of energy efficiency that it imposes and therefore neither to the verification of these parameters.
