The ducted helical fans are used for industrial plants featuring aggressive fluids, preventing contact of such fluids with the electric motor or the casing. We can produce them in S275JR, in wear resistant material, material for high or low temperatures and stainless steel 304-316L-321.
Furthermore, we provide helicoidal fans with axial fans with fin profile, fixed or variable, with belts/pulleys transmission or the traditional fan motor.
