Two-inlet low-pressure centrifugal fans. Direct-drive TMD Tecnifan

These two-inlet low-pressure centrifugal fans are made of galvanized steel, grade Z-275. They are part of the TDA Light series.
The motor shaft is connected directly to the impeller’s center plate via the hub. The motor is mounted to the suction inlet using a bracket specifically designed for this purpose. A rubber shock absorber is installed between the motor and the mounting bracket.
Features a forward-curved impeller with recessed blades, which gives the fan high rigidity and high performance.
The motor is enclosed (IP54), single- or three-phase, with 4 or 6 poles, insulation class F, and internal thermal protection. Three-speed motors are available as an option. The Light series can be installed with support legs.
