Application
The TTABD, Type "T", tubeaxial fan is designed for applications such as in-duct space ventilation, roof mounted ventilation, industrial fume exhaust and high temperature process ventilation.
The TTABD's fan propeller and hub is constructed of a precision solid casting of A319 aluminum. The TTABD has 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. The propellers are statically and dynamically balanced prior to assembly. The complete fan assembly is trim balanced after final assembly. An A240 high temperature aluminum alloy propeller and high temperature lubrication are optional to make this fan suitable for airstream temperatures up to 600°F (315°C).
