Abstract

A work station includes a pressure cabinet and a work surface forming the top of the pressure cabinet. The work surface is perforated along at least a portion of the work surface. A pressure inducing assembly is located within the cabinet below the work surface to draw air into the cabinet. A plenum is coupled to the pressure cabinet. An air chamber is mounted on the plenum and receives air passing from the cabinet through the air plenum to the air chamber. The air chamber then guides the air towards the work surface.

Claims

1. A double-sided work station having an open front side and an open back side, said work station comprising:

a pressure cabinet;

a work surface disposed on and forming a top to the pressure cabinet and being accessible by a worker from either one of the front side or the back side of the work station;

the work surface having perforations along at least a portion thereof;

a pressure inducing assembly located within the pressure cabinet for moving air through the perforations;

a first air plenum coupled to said pressure cabinet providing a channel through which air may be caused to move;

an air chamber mounted on said first air plenum and coupled thereto for receiving air from said first air plenum and guiding said received air toward said work surface.

2. The work station of claim 1, further comprising a filter disposed between said pressure inducing assembly and plenum.

3. The work station of claim 1, further comprising a divider extending across a length of said surface to divide the work surface into a first portion and second portion, the first portion being isolated from the second portion.

4. The work station of claim 1, further comprising a second air plenum coupled to said pressure cabinet providing a channel through which air may be caused to move.

5. The work station of claim 1, further comprising:

a second air plenum coupled to said pressure cabinet providing a channel through which air may be caused to move; and

a center cabinet partition disposed within said pressure cabinet for separating said pressure cabinet into a first pressure cabinet and a second pressure cabinet;

a first pressure inducing assembly being disposed in said first cabinet and a second pressure inducing assembly being disposed in the second pressure cabinet, said first pressure cabinet communicating with said first plenum and said second pressure cabinet communicating with said second plenum.

6. The work station of claim 1, wherein said perforations are formed about the periphery of the work station surface.

7. The work station of claim 5, further comprising a second filter disposed between said second pressure member and said second plenum.

8. The work station of claim 3, wherein said divider is removable.
