Low-pressure centrifugal fan. Double suction fan with fan wheel with reverse blades at high efficiency and reduced noise. Belt drive.


Low-pressure centrifugal fan. Double suction fan with fan wheel with reverse blades at high efficiency and reduced noise. Belt drive.
Air flow
V = 6.000÷300.000 m3/h
Pressure
Pt = 22÷350 kg/m2

Use: for the suction of elevated volumes of clean or slightly dusty air in the civil and industrial conditioning plants.
This series of double suction fans with rotor with reversed curved blades, which therefore has very high outputs, finds a wide use in the suction of vitiated air, solvents steams, danferous gasses; aeration of forages and cereals in the silos and buildings; tiles and ceramics drying, etc. In all those applications where the transport of air , gasses or fumes at a temperature of 40°C max at low pressure is required.

With the use of bearings with clearance C3 it is possible to effect the suction of fluids at a temperature higher than 40°C up to max 80°C.

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 backward curved fans and therefore expected Ntarget = 61 (Reg. UE N.327/2011).
ErP calculations take into account efficiency IE2 motors conforming to IEC 60034-30.
