Vibration Isolation Tables for Cleanroom Operations Chart
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
The TMC Patented Gimbal Piston Isolator has been proven by independent tests to consistently outperform the competition. It achieves both horizontal and vertical isolation down to very low input levels.

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
All systems are equipped with rugged height control valves. Virtually unbreakable, they are finger adjustable with no need for tools. The standard model maintains height to ± 0.050 in. (±1 mm.)

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.
