Sealed ball-bearing type Equipped with thermal overload Wired with separate circuits Air Inlets Greater than 8, less than 75 feet away from nearest fan For buildings wider than 35 ft., use sidewall and center ceiling inlet Fan Adjustment Thermostats that operate all fans except the minimum rate should be set 4-6°F above the heater thermostat. 80°F Desired 78°F Heater kicks on 83°F Inter-variable speed fan kicks on at 10% max 87.5°F Int. Fan at 50% max 89°F Large fan kicks on 10% - Int. fan at 100% Thermostats Use ones designed for livestock buildings. Locate it in the center of the building. Out of reach of animals. Away from cold walls. Where it can easily be seen and adjusted. Keep out of the path of furnace exhaust and ventilation inlets. Energy Conservation (PIH-92) First Consider: 1. Insulation level 2. Check for cracks, openings around doors and fans 3. Correct minimum ventilation rate 4. Correct air tempering, air distribution, animal density Then Consider: 1. Heat Exchangers 2. Solar energy (not in Indiana) 3. Geothermal earth tubes (both heat and cool) Push-pull ventilation concept Used for farrowing-nursery area Advantages: Even distribution of preheated air. Controlled air speed to reduce drafts. Constant exhaust controlled by producer. What's Needed? Small push fan and exhaust fan on variable-speed control.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
