DIDW Fans

Double Inlet Double Width (DIDW) fans have been shown to be good for filtering as well as fresh air supply along with ventilation. The aim of using such fans is to supply fresh air, room pressurization and cooling systems with air washers. The various designs of these fans are backward curved, backward inclined, forward curve, and airfoil blades. These fans are considered suitable for supply and use in commercial, process and industrial HVAC systems. DIDW has suction on both sides so that they can also be called as two centrifugal fans.
