Cook’s Fixed 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 VA is available in sizes 12 inch through 60 inch with flow rates of 1,000 CFM to 116,000 CFM and static pressures up to 7-1/2 inches. The VA features a one-piece cast aluminum airfoil propeller individually ground for balance. The VA Vane Axial Fan is also available with a full range of accessories allowing it to be adapted to many different applications.

  • High efficiency one-piece cast aluminum propeller with seven airfoil blades.
  • Minimum 12 gauge 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 subbase 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.
  • All steel fan components feature a Lorenized® powder coat finish.
  • VAH-B 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 300,000 hours for vertical units at maximum cataloged operating speed, horsepower and static pressure.
  • VA-B bearings are heavy duty regreasable ball or roller type in a cast iron housing selected for a minimum L50 life in excess of 200,000 hours at maximum cataloged operating speed, horsepower and static pressure.
  • Drives utilize oil and heat-resistant, non-static belts, and precision machined cast iron fixed pitch sheaves keyed and securely attached to the wheel and motor shafts. Drives are sized for 150 percent of motor horsepower.
  • Temperature operating range for VA-D units is from -20oF to 104oF. Temperature operating range for VA-B/VAH-B units is from -20oF to 180oF.
  • Power (BHP) ratings for all belt drive fans includes drive loss to ensure accurates selection of the motor.
    Accurate performance is assured through compliance with the AMCA Certified Ratings Program. The VA-B, VA-D and VAH-B are licensed to bear the AMCA Seal for Air and Sound Performance.
