Series 64 perforated stainless steel cleanroom tables allow uniform airflow through the work surface, and eliminate eddies and stagnant air pockets that are on or above the work surface of solid-top tables. They feature a stainless steel support frame and are ideal for vertical flow cleanroom applications. Continuous-top and perimeter-frame models are available. The table tops are made from a single sheet of stainless steel that is perforated, forming a continuous, smooth top. Holes are available in nominal sizes of 1/4 on 1/2 in. staggered centers, 3/8 on 1/2 in. straight centers, and 3/4 on 1 in. straight centers.
