  • Ventilation system for animal enclosures
    Patent number: 4829885
    Abstract: A ventilation system for use in animal confinement enclosures. A duct extends the length of the enclosure and includes a back pressure plate having a plurality of holes. A flexible baffle is positioned adjacent the back pressure plate exterior of the duct.
