Simple Fixes Often Result in Substantial Fuel Savings

Leaky tunnel fan shutters can prove to be very costly during cold weather. Cold air leaking in through fan shutters not only results in excessive fuel usage and wet litter problems in the vicinity of the fans but also leads to problems throughout the house. For instance, excessive fresh air entering through leaky tunnel fan shutters can essentially rob the remainder of the house of fresh air resulting in air quality issues for birds far from the fans. Furthermore, when the tunnel fan end wall ar...ea is cool due to excessive shutter leakage, bird density in this area of the house tends to be lower, often resulting in an insufficient number of birds to sufficiently activate feeder control pans.
