FDFB-6.3-1500

General information
Equipment type:	Forced draft fan
Name:	FDFB-6.3-1500
English name:	VDN-6,3-1500
Notes:	Backward curved blades. Running wheel on the electric motor shaft.

Description for FDFB-6.3-1500
Single inlet centrifugal FD Fans are used for air delivery into combustion chambers of boilers with the capacity of 2.5- 950 t/h operating with balanced draft (secondary blast). It is allowed to use these fans in processing systems to handle air with the temperature not more than 70 °C. Single inlet centrifugal FD Fans can have right-hand or left-hand rotational direction. The right-hand rotation is in a clockwise order and it should be defined at electric motor side. The blades of impeller are backward curved.
