Abstract: A ceiling ventilation inlet includes a housing having an air inlet aperture, an air outlet aperture, and a baffle supported for linear movement adjacent the air outlet aperture. A spring is positioned such that the baffle moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle and enters the livestock confinement building in a 360 degree dispersion pattern. The spring causes the baffle to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment the greater the air outlet area becomes. Since the inlet is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate.

Abstract: A ceiling vent diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent. The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch associated with the vane directs the outflow of air and also laterally disperses air within the vent. The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.

The intake is firstly comprised of a hollow building body. The body extends from outside the building, through a ceiling or wall of the building with an opening extending into the building for bringing fresh air into the building from the outside. An air intake housing with at least one opening is attachable to the building body on the inside of the building at the body opening through which fresh air from outside may flow. A pair of independently adjustable deflectors are pivotally mounted onto the housing adjacent the opening in opposing relationship to each other to manually open and close the opening as well as direct the fresh air from ceiling to floor as the fresh air is drawn into the building through the fresh air intake.
