An adjustable and stable horizontal resonant frequency which is both load-independent and insensitive to environmental changes. The frequency range can be adjusted from 1 Hz down to 0.5 Hz or below.

Overall height under 17 inches; less than half the length of a pendulum of the same frequency.

A lightweight pendulum design dramatically reduces the “intermediate mass” resonance common to prior pendulum system designs; the total floating mass is only a few pounds and its associated resonance is above 20 Hz in most applications.

Fully modular design fits TMC System 1 leg shells and allows for easy removal and maintenance of the diaphragm assembly.

Simple two-screw adjustment allows isolator’s level to be adjusted with the payload floating. Adjustments are readily accessible on isolator’s top plate.

TMC’s standard mechanical overtravel limit prevents dangerous diaphragm ruptures if the system is inflated unloaded.

A horizontal damper provides excellent horizontal damping without increasing the system’s resonant frequency.  

Reduced tilt-to-horizontal coupling makes the system ideal for use with TMC’s line of active products – including the Precision Electronic Positioning System (PEPS^®) and our PEPS-VX^®3-DOF active cancellation system.

An improved vertical damping characteristic due to the increased ratio of the surge tank (not shown) to top chamber volumes.

Available in a range of load capabilities from 250 lb. to 2,500 lb. per isolator.
