• TDA T3R

GENERAL CHARACTERISTICS

Double inlet and triple impeller centrifugal fans for low and medium pressures, manufactured in galvanized steel, quality Z -275.

Free output shaft for belt driven transmission. Includes double shaft end to facilitate the assembly in eight possible orientations.

The forward type impeller is manufactured with inserted blades (tabbed construction), which gives the fan great rigidity and high performance. The bearings are stiff, self aligning ball bearing type, sealed and lubricated for life.

The reinforced series construction contains three TDA series fans mounted in tandem on the same axis, reinforced with frames, forming a unit.
