Fiber-Reinforced Plastic (FRP) provides excellent corrosion resistance and weight saving when compared to carbon steel. Fiberglass fans can weigh 15 to 40% less than traditional steel Class II utility vent sets. Cook fiberglass products are constructed of corrosion resistant fiberglass resin, which is formulated to achieve a Class I flame spread of 25 or less. All resin is protected with a chemical, flame and ultraviolet top coating. A neoprene seal protects the shaft. Motors and drives are enclosed in a compartment, protected from corrosion and weather. This FRP was successfully tested with more than 90 corrosive materials, in environments 150 to 210⁰F. See page 4 for a full list of corrosion and temperature ratings.

Typical Applications

  • Water Treatment Plants
  • Wastewater Treatment Plants
  • Pumping Stations
  • Indoor Swimming Pools
  • Aquariums
  • Laboratory Exhaust Systems
  • Chemical Process Facilities
  • Pulp and Paper Mills
  • Fertilizer Manufacturing
  • Chemical Storage Facilities
  • Battery Charging Stations

Wheel

This first of its kind, centrifugal airfoil backward inclined wheel, is molded and formed as one solid piece. It has more than 140 precisely cut, glass mats that are woven into a single mold. Added to this process is a precision machined aluminum hub. Vinylester resin is then injected in the mold encapsulating the hub. This mold is precisely designed to produce a wheel that does not require any hand layup work. Available in clockwise or counter-clockwise rotations. Choose a standard width or a high pressure (HP) 66% width wheel to meet specific needs. Wheels are balanced in accordance with AMCA Standard 204-05, Balance Quality and Vibration Levels for Fans.
