This centrifugal fan is generally used for factories, manufactures, basements and others that require wind circulation in a large enough room. Centrifugal fans are a solution to dealing with stuffy and humid rooms, especially those that are large or wide.
This centrifugal blower fan is used in a room that is not too large (small room capacity), but requires a long exhaust distance or thrust. In its operation, a centrifugal blower uses a ducting system application so that all hot spots can be removed or sucked. The ducting length must be adjusted to the static pressure or the thrust contained in the centrifugal blower. If the ducting is too long and there are many indentations there will be lost static or loss of pressure.
