The CFI heat-resistant duct fan can be freely adjusted and can be installed both horizontally as well as vertically in the vertical or horizontal part of the pipe system.
The fan generates mechanical draught in gas, oil and steam installations with a maximum flue gas temperature of 300 ° C.
The CFI can be mounted indoors and outdoors at ambient temperatures from -40 ° C to 50° C.
The CFI duct fan has a backward inclined centrifugal impeller made of cast aluminium. The fan’s housing is made of acid-proof 316 steel and is equipped with an energy-saving, fully encapsulated, fully adjustable motor with closed and permanently lubricated bearings. The motor and impeller form a complete unit (drive), which can be removed from the fan’s housing without the need to remove the fan from the pipe system. The connecting pieces are suitable for most prefabricated chimney systems.
The CFI channel fan can be used only for systems that are powered by natural gas, bottled gas / butane or fuel oil, but never for solid fuel incinerators.
The CFI is not suitable for pulsating boilers.
