Axial fans


Type VT Vaneaxial Fan, Belt Driven


The VTBD, Type “VT”, vaneaxial fan incorporates a vane section that is attached to the discharge of the TTABD tubeaxial fan for higher pressure applications. The VTBD is designed for applications such as in-duct space ventilation, roof mounted ventilation, industrial fume exhaust and high temperature process ventilation.

The VTBD’s fan impeller and hub is constructed of a precision solid casting of A319 aluminum, having seven airfoil blades and a malleable split taper lock bushing for mounting to the shaft. The blade angle setting is 34° at 3/4 radius. Impellers are statically and dynamically balanced prior to assembly. The complete fan assembly is trim balanced after final assembly.
