FDFB-28x2-I

General information
Equipment type:	Forced draft fan
Name:	FDFB-28x2-I
English name:	VDN-28X2-I
Notes:	Backward curved blades

Description for FDFB-28x2-I
Double inlet centrifugal FD Fans are designed for air delivery into combustion chambers of pressure-fired boilers with the capacity of up to 2500 t/h. High-pressure FD Fans overcome full resistance of air-gas flow path. Double 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.
