Abstract
A work station having an environmental controller for maintaining air flow in and through the work station at a user-selected level. The work station includes a pressure cabinet and a perforated work surface forming the top of the pressure cabinet. A pressure inducing assembly is located within the cabinet below the work surface to draw air into the cabinet and create a negative pressure in a work space defined above the work surface. A support coupled to two sides of the pressure cabinet provides a channel for air flow from the pressure cabinet to an air chamber located above the work surface. Air is drawn from the air chamber generally downward toward the work surface by the negative pressure created in the work space to provide an air curtain substantially surrounding the work surface.
