Chore-Time’s innovation delivers:

• More air volume with fewer fans – 29,700 CFM at 0.05 inches static pressure in recent independent wind tunnel tests.
  
  
• More consistent air flow – HYFLO Doors don’t suffer the 12-15% loss of efficiency and air speed typical of dirty louver-style shutters.
  
  
• Compressible, one-piece cone for 60-inch-on-center (152.4-cm) installation.
  
  
• Sturdy, corrosion-resistant fiberglass housing with cast aluminum blade and corrosion-resistant components.
  
  
• Automatic belt tensioner uses arm and pulley arrangement to provide consistent belt tension.
  
  
• Heavy-duty, cast iron, air-handler type bearings are self-aligning, pre-lubricated, and include a zerk fitting, as well as being shielded from moisture and dust.
  
  
• Pre-assembled including doors, with a true flush mount.
  
  
• Just two moving parts for greater reliability and easier cleaning.
  
  
• Chore-Time’s generous extended warranty including limited lifetime coverage for housing and blade, and a bonus year on motors. (See Chore-Time full written warranty for complete warranty details.)
