ABSTRACT:
A pneumatic wall-vent closer for use in a thermal-pneumatic automatic temperature control system. The system is used to maintain constant temperature in livestock confinement buildings. The wall-vent closer attaches between the sill of a wall-vent in a confinement building and the wall-vent. As the temperature in the confinement building varies, the pneumatic wall-vent closer automatically opens and closes the wall vents to allow more or less air into the confinement building to maintain a pre-set stable temperature.
