Abstract
The present invention relates to a device for displaying a condition of air flow to or from a ventilated rack of animal cages in which a damper is coupled between the ventilated rack and an air inlet or exhaust outlet. Air pressure is measured within the damper. A condition of the measured pressure is visually displayed. The display can include a plurality of color coded portions for indicating that the condition is within or outside of a preferred operating range, thereby providing a visual assurance that the ventilated rack of animal cages is maintaining a barrier condition. In addition, the display can indicate a value of the measured pressure or a flow rate. When the display indicates that the condition of the air flow is outside of the preferred operating range, the damper can be manually or automatically adjusted to enable the preferred operating range to be obtained. A barrier condition of the rack is maintained when the preferred operating range is maintained.
