Vibration Isolation Tables for Cleanroom Operations
From TMC

• Suitable for cleaner than Class-100 cleanrooms; includes stainless steel top and ducted air exhaust for clean, particle free operation
• Choose from two tabletops: brushed and electropolished 304 stainless steel
• Patented Gimbal Piston Isolators achieve both horizontal and vertical isolation down to very low input levels
• Tiebars are welded on the inside, so no weld bead is exposed
• High stiffness, stainless steel frame is easy to clean with no horizontal seams or ridges
• Load-carrying capacity of up to 500 lbs. (227 kg) for balanced loads
• Front support bar comes standard

The all-stainless steel vibration isolation workstation is a high-performance, pneumatic vibration-dampening table designed from the floor up for maximum cleanroom compatibility. Isolation is provided by the patented Gimbal Piston element that provides unsurpassed performance in isolating optical tables, electron microscopes, precision balances, and scanning-tunneling microscopes. These workstations can be alcohol wiped with a lint-free cloth and are double wrapped in plastic at the factory prior to shipping.

Gimbal Piston Isolators

Thin-Wall Rolling Diaphragms

An integral part of the Gimbal Piston, the thin-wall, dacron-reinforced, rolling diaphragm air seals are only 0.020 in. (0.5 mm) thick and extremely flexible. They do not stiffen the spring as thicker rubber diaphragms do.

Height Control Valves

Internal Piston Travel Restraint
Unique in the industry, TMC provides husky, tamperproof, built-in piston travel restraints. The restraints are completely independent of the table valves and have been ram-tested at forces above those produced by the pistons operating at full pressure. They cannot be decoupled accidentally and do not interfere with setting up and using the table, but simply protect against overtravel without the use of external bars that create hazardous pinch points. Heavy loads, including the top plate, can be safely removed from a table in full operation.

Tiebar Gussets
Exclusive TMC tiebar gussets increase table frame rigidity. They compensate for the elimination of the front tiebar in order to provide kneewell space.

Rugged Built-in Leveling Feet
Table legs include built-in fine-thread 3 in. (75 mm) diameter screw jack levelers with 1/2 in. (13 mm) travel, provision for external adjustment and a handy adjustment wrench. The base is a solid, slightly domed shape to assure solid, wobble-free contact with sloping or irregular floors.

Casters
A set of four retractable casters with a total weight capacity of 1,000 lbs. (450 kg) can be mounted to the base of the table legs.
