COOK adjustable pitch vane axial fans are available in direct and belt drive models offering high efficiencies and high static pressures in a space-efficient inline package. The AVA is available in sizes 35 inch through 79 inch with flow rates of 400 CFM to 213,403 CFM and static pressures up to 13 inches. The AVA features cast aluminum airfoil blades that can be pitch adjusted to achieve a broad range of performance. The AVA adjustable pitch vane axial fan is available with a full range of accessories allowing it to be adapted to many different applications.

  • High efficiency nine blade cast aluminum propeller assembly with airfoil blade design.
  • Minimum 3/16” steel housing with continuously welded seams, and integral inlet and outlet flanges pre-punched for mounting.
  • Copper lubrication lines are standard on belt drive units and also standard on direct drive units when applicable.
  • The motor plate is attached to a heavy welded sub-base and features threaded studs for positive belt tensioning.
  • Direct drive units feature a totally enclosed motor installed in a motor tunnel surrounded by welded straightening vanes.
  • Belt drive units feature an inner drum that encloses the driven sheave, shaft and bearings. The low-drag dual tunnels, separating belts from the airstream, also protect the extended lubrication lines. Removable covers provide access to the shaft, bearings and belts. All steel fan components feature a LorenizedTM powder coat finish. Bearings are designed and tested specifically for use in air handling applications. Bearings are heavy duty regreasable ball or roller type in a cast iron pillow block housing selected for a minimum L50 life in excess of 500,000 hours for horizontal units and L50 life in excess of 250,000 hours for vertical units at maximum cataloged operating speed, horsepower and static pressure.
  • Drives utilize oil and heat resistant, non-static belts and precision
    machined cast iron sheaves which are keyed and securely attached to the wheel and motor shafts. Drives are sized for 150 percent of motor horsepower.
  • Power (BHP) ratings for all belt drive fans includes drive loss to ensure
    accurates selection of the motor.
