Poultry Fans and Shutters   Fan Performance could save 14% or more in energy costs compared to Chore-Time's own great-performing 54-inch High-Capacity Fan, often while using the same number of fans! All ENDURA® Fan components were designed by Chore-Time to maximize overall fan efficiency.   Shutter Performance do not suffer the typical 12-15% loss of efficiency and air speed typical of dirty louver-style shutters, so air speed is maintained to the end of the flock, when you need it most. Shutters improve fan performance by minimizing obstructions during fan operation. They deliver up to 10% more air than traditional shutters with 75% less opportunity for air toleak through.   Adaptability Can be installed 60 inches (152.4 cm) on center over 56.5-inch (143.5-cm) framed openings. For retrofit, will fit over openings for many 48- through 54-inch (121.9- through 137.2-cm) fans. Black HDPE (high-density polyethylene) cone aids in light control. Capable of variable speed operation.       Durability Automatic belt tensioner uses an idler arm and pulley to provide constant belt tension. Rugged air-handler bearings are shielded from dust and moisture, self-aligning, prelubricated and include a zerk fitting. Aerodynamic three-wing, heavy-duty fan blade.   Our fans:
