Fan Blower Motor Centrifugal Exhaust Fan For Air Handling Unit AHU Centrifugal Blower
Centrifugal fans can be manufactured to various casing thicknesses and with various forms of construction according to usage. Thus at one extreme they can be handling clean air whilst at the other, air or gas handled can be at a temperature well above ambient and/or may contain substantial quantities of moisture and/or solids. It may also be at high pressure such that loadings on the fan casing and the associated ducting system are much higher than usually expected for a HVAC fan.
Connection to the ducting may be via flexible connections, or alternatively may be directly connected. In the latter case the fan has to withstand additional loads due to the dead weight of these connections. Where gases, or the surrounding ambient atmosphere, are at a high or low temperature, additional loading can result from the effects of expansion or contraction.

The two-outlet channels are termed channels 1 and 2. There are no conclusive differences in the measured data for either channel. The designations 1 and 2 only show which channel is throttled and where the pressure measurements are made.
Variation of total pressure in channel 1 versus flow rate at each channel. Variations in the total pressure of both channels are fairly similar. It does not make any difference which of the two outlet channels has a constant throttle point when the other is throttled. Pressure in the fixed throttled channel remains constant when the other channel is throttled. This is important since it shows that if application setting in one channel changes, the users of the other channel will not experience higher or lower heads.
