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

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. |

Power Cord Pass-Through
Standard on all rod tops. |

QuietTop™ Rod Top Benches
Rods float in a non-outgassing elastomer that dampens noise and vibrations. |

Elastomer "potting" eliminates welds around rods, dampens vibration and eliminates particle traps! |

Competitor's Design
Conventional welds trap particles and amplify noise and vibrations. |

OpenTop™
Perforated Top
Hidden reinforcements minimize dead spots, add strength, and eliminate deflection bounce-back ("oilcan effect") without dead spaces. |
 |
|
Competitor's Design
Conventional perforated tops rely on "blank out" support panels, which create turbulence in a cleanroom laminar flow. |

Full Bullnose
Front Edge
Standard on all QuietTop™ models, Terra's one-piece bullnose enhances worker comfort while optimizing vertical laminar airflow—without welds or cracks. |
 |
|
Competitor's Designs
Crimped edges leave cracks where particles collect. |
 |
| Welded bullnose harbors contaminants; sharp bottom angle creates turbulence. |
 |
|
|
OpenTop™ Perforated
Top Benches
Preserves maximum open space to facilitate laminar airflow without sacrificing strength or rigidity. |
