Vane Axial High Pressure Fans

Overview

  • Models VAB, VABS

    Belt Drive - Vane Axial fans are designed for commercial and industrial applications where large volumes of air are required at moderate to high pressures. Belt drive vane axial fans accommodate for final system balancing and have manually adjustable blade pitch. These fans are an excellent choice for variable air volume HVAC systems, clean rooms, parking garage exhaust, and tunnel ventilation. For sound critical applications, belt drive vane axial fans are available with Greenheck's Sound Trap Housing.


  • Models VAD, VADS

    Direct Drive - Vane Axial fans are designed for commercial and industrial applications where large volumes of air are required at moderate to high pressures. Direct drive vane axial fans have manually adjustable blade pitch and require minimal maintenance. These fans are an excellent choice for variable air volume HVAC systems, clean rooms, parking garage exhaust, and tunnel ventilation.

Sound Trap Housings effectively decrease inlet and outlet sound power levels while only slightly increasing fan length and adding no additional pressure drop to the system.

    Features

    A. A perforated steel inner liner directs sound waves into sound absorbing material between the inner liner and solid steel outer shell converting acoustical energy to heat.

    B. Two inches of sound absorbing fiberglass is sandwiched between the inner and outer shell. The fiberglass meets requirements of NFPA 90A and 90B, ASTM C 1071 Type I and TIMA Standard AHC-101. The liner meets all requirements for 25 flame spread or 50 smoke development when tested in accordance with ASTM-E84, UL-723 and NFPA-255.

    C. Steel bands seal the insulated cavity against pressure loss.
