Abstract
An air velocity control unit includes first bars fixed using a frame. Second bars are disposed below the first bars. The second bars are alternatively arranged between the first bars. The second bars are connected with each other. The unit further includes a control member for moving the second bars upwardly and downwardly to control the air velocity. A connecting member connects the second bars to the control member. Clean air flows into a clean room by a controllable velocity in accordance with the upward and downward movement of the second bars.
Claims20
An air velocity control unit comprising:
- a frame;
- first bars affixed within the frame;
- second bars disposed below the first bars and arranged alternatively between the first bars, the second bars being connected with each other;
- a control member for moving the second bars upwardly and downwardly to control air velocity flowing between the first and second bars into a clean room;
