LOW PRESSURE CENTRIFUGAL FAN. FORWARD CURVED bladed propeller. SAFETY BELT.
This series is also used where it is necessary to transport air at a maximum temperature of 90°C at low pressure. For temperatures of the transported fluid from 90°C to higher than 350°C, a small heat-stop fan is threaded on the shaft between the support and the spiral; In addition, the fan is painted with special aluminum paint suitable for high temperatures.
ErP : These fans are within the scope of 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).
These series are centrifugal forward curved fans and therefore Ntarget = 42 is expected (Reg. UE N.327 / 2011).
Efficiency IE2 motors conforming to IEC 60034-30 are taken into account in ErP calculations.
When using Variable Speed Drives, please be aware of possible overheating of the motor due to lower rpm/Hz than recommended by the motor supplier.
