RT8centrifugal high temperature draft fans used in the hot air exchange , circulation and inducing the wind inside the furnace ,it also can be used on collocating heat wind conducting of other equipments which can generate the origin of heat .RT8 centrifugal fan adopts the crust with double-deck and thermal insulating ,.It has the advantages that the heat wind temperature won't be out of the crust,t is safe,energe -saving and the noise is low.the structure is also compact,the fan can stand the temperature above 300oC and it can be used in transferring the hot air blew 700oC by improving the design ,the main fan material can be chosen according to the furnace temperature.
