Propeller Tube Axial Inline 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 TDI (Direct Drive)

Medium Pressure Axial, Tube Axial, Medium Pressure Vane Axial

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 300° F (149° 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).

Model TBI-CA (Belt Drive)

Medium Pressure Axial, Tube Axial, Medium Pressure Vane Axial

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 TBI-FS (Belt Drive)

Medium Pressure Axial, Tube Axial, Medium Pressure Vane Axial

The TBI-FS axial series are belt driven and use fabricated steel, airfoil propellers. The key features of the TBI-FS axials are compact size, mounting flexibility, and ease of performance adjustments. Additionally, the combination of the fabricated steel impeller and vented internal belt and bearing enclosure enables this product to be used for high temperature ventilation. Typical applications include general ventilation, high temperature process exhaust, and emergency smoke exhaust, where the TBI-FS is a UL Listed Power Ventilator for Smoke Control systems. The TBI-FS performance capacities are up to 77,000 CFM (130,000 m³/hr) and static pressures up to 4.5 inches w.g. (1,120 Pa).
