FDF-DSA-31.5-DB

General information
Equipment type:	Forced draft fan
Name:	FDF-DSA-31.5-DB
English name:	VDOD-31,5-S
Notes:	Detachable blades

Description for FDF-DSA-31.5-DB
Two-stage axial FD Fans are used for air delivery into combustion chambers of boilers with the capacity of up to 2650 t/h operating with balanced draft (secondary blast). These fans meet the parameters of boiler air path provided the installing two fans of such type for one boiler. All of such fans have left-hand rotational direction. The left-hand rotation is counterclockwise and it should be defined at electric motor side.
