FDFB-11.2-1000

General information

Fan type:	Single inlet centrifugal FD fans of FDFB type
Name:	FDFB-11.2-1000
Alternative names:	VDN-11,2-1000; ВДН-11,2-1000
Notes:	Backward curved blades. Running wheel on the electric motor shaft.

Description

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.
