Tecnifan TDA \u2013 SR 3100 dual-inlet centrifugal fan \u2013 53,800 m\u00b3\/h<\/h2>\n

Two-inlet centrifugal fans, semi-reinforced series, made of galvanized steel, grade Z-275. Free-running output shaft for belt drive. Includes a double-shaft end and a square frame, which facilitates assembly in eight possible positions. <\/span><\/p>\n

\"Centrifugal<\/a><\/p>\n

The forward-curved impeller is manufactured with integrated blades, which give the fan high rigidity and high performance. The bearings are rigid, self-aligning ball bearings that are sealed and lubricated for the entire service life. <\/span><\/p>\n

The small-series design consists of side frames and a support crossbar, while the large-series design includes a triangular frame and bearing supports.<\/p>\n\n
