Product Overview

Terra Universal manufactures the most advanced lines of electropolished 304 stainless steel work benches available for high-technology cleanrooms.

QuietTop™ Rod Top Benches
Rods or Perforations?
Both rod and perforated tops are designed to optimize the vertical laminar flow of particle-free air inside a cleanroom. From that point of view, both are superior to solid tops, which block air flow and create significant turbulence both above and below the work surface.

Perforations provide more surface area for supporting parts, but they do generate some turbulence in the gaps between the cut-outs. Terra's standard OpenTop™ perforations have a .75" diameter and open up 40% of the total benchtop for the air flow. Other hole patterns and sizes are available.   Rods create virtually no turbulence, but their open structure leaves little space to support small tools and parts. To solve this problem, Terra offers clip-on equipment mounts. Terra's standard QuietTop™ design uses .25"-diameter rods on 1" centers. Call for other rod sizes and configurations.
