Home > Products > Industrial fans > Centrifugal F.D.-fans
Centrifugal single and double-side suction FD fans of ВДН and ВДНх2 types are meant for air delivery into the furnace of stationary steam boilers with capacities ranging from 35 to 2,650 t/h. Apart from this, they are also allowed to be installed at processing plants for clean air handling. Maximum allowable temperature of handled air at FD fan inlet must not exceed +100 ◦C.
