New Emergency Vent System Saves Hogs

New Emergency Vent System Saves Hogs HOG EQUIPMENT & IDEAS Hog Equipment & Ideas (351) 8-2-34 "When two of our neighbors lost all their hogs, we decided we'd better come up with something to protect ourselves," says Gordon Lee, Fairfax, Minn. He and John Simmons, his electrician, developed a new emergency ventilation system for confinement buildings. The basic system consists of two electric fans, two deep cycle batteries, a trickle charger, and controls. When the power to the building shuts down ù for whatever reason - the controls trigger the fans, which immediately begin ventilating the building. The fans operate for up to 9 hours on fully-charged batteries. "A timeclock runs the fans for 5 min. or more each day so they're always ready. There's also a test switch so you can check the system whenever you go through the barn, if desired," says Lee. The system fits either 110 or 220-V systems and a local electrician can easily wire it up with the included instructions. Lee has a 30 by 80-ft. farrowing building and says the basic system ù which includes two 12-in. fans ù would keep the building more than adequately ventilated in case of a power outage. The basic system, will work on any type confinement building. An alarm, to let you know when the power goes off, is optional.
