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.
