BP
Low-pressure centrifugal fan. Impeller with blades curved forward. Directly coupled motor.

Pressure
Pt = 15÷220 kgf/m2

Use: for the removal of clean or slightly dusty air. They have high efficiency and reduced noise level, the fans of this series are largely used, inventilation, conditioning, drying, cooling, mechnical draft, and toxic gas elimination plants.
The temperature of the fluid transported must not exceed 80°C without cooling fan and 150° C with cooling fan. For higher temperatures it is necessary to modify the construction of the fan.
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 = 49 (Reg. UE N.327/2011).
ErP calculations take into account efficiency IE3 motors conforming to IEC 60034-30.
