TDA double-inlet centrifugal fans are manufactured from galvanized steel, grade Z-275, and are designed for belt drive with a free-running output shaft. The double-shaft end is designed to facilitate assembly in eight possible orientations. The forward-curved impeller features a ribbed design that provides the fan with high rigidity and high performance. The bearings are rigid, self-aligning ball bearings, sealed and lubricated for the entire service life. TDA fans, designed for low and medium pressures, are manufactured in three designs (series) depending on the application range: Light (L), Semi-Reinforced (SR), and Reinforced (R). To complement the selection, double-row impellers (tandem) are available for the light, semi-reinforced, and reinforced series, and triple-row impellers are available only for the reinforced series. The TDA model range includes twenty sizes, from 7/7 to 30/28, one of the most comprehensive ranges on the market, capable of handling airflow rates up to 162,400 m³/h and total pressures up to 1,420 Pa. They cover a temperature range from -20°C to 80°C or 110°C, depending on the series.
