ENDURA® High-Performance Corrosion-Resistant 57-Inch (145-cm) Fan

Fan Performance

  • Chore-Time's Energy-Efficient, Standard-Mount ENDURA® Fan could save 14% or more in energy costs compared to Chore-Time's own great-performing 54-inch (137-cm) High-Capacity Fan, often while using the same number of fans!
  • Motors are selected for each fan model to optimize its performance efficiency. Extensive motor testing is completed in our on-site wind tunnel under various operating conditions.
  • All ENDURA® Fan components were designed by Chore-Time to maximize overall fan efficiency.

Shutter Performance

  • Chore-Time's HYFLO® Shutters 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.
  • HYFLO® 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 to leak through.

Exceptional Materials

  • Durable long glass fiber composite shroud and HYFLO® Shutter Doors contain 35% fiberglass for strength and to limit expansion and contraction.
  • Galvanized, powder-coated fan drive, support structures and flush-mount box. Optional stainless steel fan blade and shaft.


  • Extensive durability testing under both extreme high and extreme low temperatures.
  • 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.


  • 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 (122- through 137-cm) fans.
  • Black HDPE (high-density polyethylene) cone aids in light control.
  • Capable of variable speed operation with the use of a variable frequency drive.

Mounting Options

  • The standard-mount model of Chore-Time's ENDURA® Fan offers the best performance and easiest installation.
  • Chore-Time's flush-mount ENDURA® fan delivers high air flow and efficiency and also eliminates obstructions inside the poultry house.
  • Two mounting options for the flush-mount model are possible – through the wall or over the wall.
