Duct fans are really useful solution in many ventilation installations because of their easy construction, easy assembly and the low costs of construction and operation. They connect the advantages of axial and radial fans because they keep the axial air flow direction with the possibility of overcome the bigger installation resistances. RKO fans operation is characterized by the low volume emitted to the environment.
Duct fans are designed for use them in the intake and exhaust ventilating installations made in the industrial and general building engineering. Flowing air can be polluted with the vapors and corrosive gases and polluted with the gases within the limits which are permitted by the environment protection regulations.
Series of types of fans include 6 dimensions.
Fans consist in:
Duct fans can work in each position.
