Tube Axial Fans

Tube axial fans are designed for applications in ducts or intake/exhaust systems which have low resistance to air flow. The tube axial fan is encased in a cylinder which helps collect and direct the fan's flow. With sizes available from 20" to 72" and cfm ranges from 1,250 to 60,250, the tube axial fans are very efficient in their class of fans. Standard construction includes a welded steel housing tube and cast aluminum fan blades for spark resistant construction. Four and six bladed propellers are available in direct and belt driven models. The direct drive tube axial fans are designed to be used in applications where corrosive and contaminated material are not a problem. The belt driven models are designed for applications where corrosive materials are a factor. Typical applications include exhaust for paint spray booths, mixing rooms, booster service, and many other industrial ventilating requirements.

Vane Axial Fans are adaptations of Tube Axial Fans using pre-rotative or post-rotative vanes to improve the fan's efficiency and increase working pressure. Standard features include welded steel tube and vanes, four or six blade cast aluminum airfoil blades, in belt or direct drive designs. Inlet or discharge bell, guards, access doors, and mounting legs are available as options. Belt driven units have the motor mounted out of the air stream for applications involving corrosive fumes, smoke or hot air.

Panel Fans

Sound Fighter Panel Fans are designed to meet a variety of applications from general ventilation in commercial facilities to heavy duty industrial applications involving higher static pressures and cfm requirements. Panel fans are available with diameters of 24" to 96" with cfm ranges of 4,500 to 185,000. The FHI fans can meet the air requirements for most exhaust, supply or reversible services. The Sound Fighter FHI fan is made with a rugged, welded, all-metal structural frame for added support and lower vibration. The panel is a deep spun venturi-type orifice for quieter, more efficient operation. A full line of accessories are available for the FHI line, including wall boxes, guards, dampers, and rainhoods.
