Membrane Air Spring Isolators

Membrane Air Spring Isolators

The Unick Membrane Air Spring Isolator is constructed in a cast aluminum body. It consists of an air chamber that is sealed with a reinforced, flexible diaphragm. When compressed air is inserted through the inlet valve, the isolator supports its payload using a piston which is located on the top of the diaphragm. We can calculate the load capacity of the isolator by using the pressure on the diaphragm and the effective area of the diaphragm. The permissible Temperature Range is -20deg C to +90 deg C.

The typical pneumatic isolator design incorporates dual air chambers. It has a very low-level natural frequency. It can be removed the vibration frequency below 2 Hz.

Membrane Air Spring Isolators is the leading manufacturer and supplier of high-quality and technologically advanced anti-vibration pads for all industrial machines

Profile Projectors etc.



In case of Sensitive Equipments like Coordinate Measuring Machine (CMM), We can achieve highly effective vibration isolation by using “Cradles” or “Custom designed Rigid Frames”. Cradles increase the stability of self levelling pneumatic isolation system by lowering the center of gravity. A cradle support frame is used to position the membrane air spring isolators achieve the reduction in passive vibration. Second, it is also used when a machine base cannot be modified to place the isolators and then rigid frame is required.
