Tube Axial Fans
Greenheck's axial inline fans are designed for ducted indoor or outdoor applications. They are available in both direct drive and belt drive and with cast aluminum or fabricated steel propellers. All models include integral flanges for airtight duct connections and can be mounted in any configuration - horizontal, vertical, or at an angle.
The TDI and TBI axial inline series are available in three levels of construction to match each product's strengths to the specific requirements of any commercial or industrial application. Tube Axials are best suited for pressures up to 1.25 inches w.g. (312.5 Pa). Medium Pressure Axials are designed for pressures up to 3.5 inches w.g. (875 Pa). Medium Pressure Vane Axials are capable of pressures exceeding 4.0 inches w.g. (1000 Pa).
Model TBI-FS has a fabricated steel hub and airfoil blades. It is suitable for continuous high temperature (400ºF/204ºC max.) for inline configurations, (500ºF/260ºC max.) for roof upblast configuration and is available with UL Power Ventilators for Smoke Control Systems. The universal mounting system accommodates any vertical or horizontal installation configuration. Typical applications involve clean air, industrial processes, and hightemperature exhaust. Capacities range from 3,300 to 76,000 cfm (5,607 to 129,124 m3/hr) for inline configurations [5,500 to 74,000 cfm (9,345 to 125,727 m3/hr) for roof upblast configurations] and 3.5 in. wg (868 Pa). Bolt-on straightening vanes are available for increased efficiency. AMCA Licensed for Sound and Air Performance.
Model TBI-CA (Belt Drive)
The TBI-CA axial series are belt driven and use cast propeller, airfoil propellers. The key features of the TBI-CA axials are compact size, mounting flexibility, and ease of performance adjustments. Additionally, the combination of the cast aluminum impeller and sealed internal belt and bearing enclosure allows this product to meet spark resistant specifications. Typical applications include warehouse or industrial ventilation and paint booth fume exhaust. The TBI-CA performance capacities are up to 96,000 CFM (163,000 m3/hr) and static pressures up to 3.25 inches w.g. (810 Pa).
Model TDI (Direct Drive)
The TDI series of axials maximize efficiencies with cast aluminum, airfoil propellers. Their primary attributes include compact size and minimal maintenance. Additionally, TDI fans can be used with variable frequency drives to accommodate modulating performance requirements. Typical applications range from clean air exhaust to emergency smoke control where the TDI has been tested to exhaust airstream temperatures up to 300º F (149º C) for a minimum of 5 hours. The TDI series has performance capacities up to 95,000 CFM (161,000 m3/hr) and static pressures up to 2.75 inches w.g. (685 Pa).
