Abstract
A ventilating air filtering and distribution device particularly well suited for installation in the ceiling or walls of an environmentally controlled room which room requires a laminar ventilating air flow. The device includes a plenum structure defining a dirty air plenum chamber, and has a dirty air inlet in one face and a clean air outlet in an opposite face. A pair of damper-diffuser plates are adjustably attached to a support beam disposed proximate the clean air outlet, thus, leaving the dirty air inlet unobstructed with support structure. Additionally, filter media is disposed across the clean air outlet to filter the ventilating air as it exits the plenum structure through the clean air outlet.
Claims15
A ventilating air distributing device comprising:
- a plenum structure defining a plenum chamber and having an inlet in one face and an outlet in the opposite face;
- damper-diffuser support means attached to said plenum structures proximate said outlet therefrom;
- an adjustment rod mounted to said support means and coaxially disposed relative to and extending axially toward said inlet for selective axial movement toward and away from said inlet;
- at least two parallel spaced apart mutually coaxially disposed perforated plates coaxially disposed on and attached to the rod proximate the end of said rod closest to said inlet for movement toward and away from said inlet with said rod;
- said perforated plate farthest from said plenum structure inlet is larger in area than said perforated plate closet to said plenum structure inlet, and said damper-diffuser support means comprises a beam attached at its opposite ends to the side walls of said plenum structure and extends across said outlet.
