PLCTS's Three-Pendulum Pneumatic Isolation Table is designed for ultra-high-precision research, delivering performance comparable to top international brands. The independent cylindrical legs eliminate system-wide resonance, while the tri-wire pendulum design ensures ultra-low vibration levels and highly accurate repositioning after disturbances.
Laminar flow damping and a hybrid chamber structure enhance damping efficiency and reduce the system's natural frequency within a compact footprint.
The table features a high-permeability SUS430 stainless steel surface, precision-ground for flatness and finished with a non-reflective matte edge. An M6-threaded hole array allows flexible component mounting. A high-power, ultra-quiet air compressor is included as standard—making it an ideal choice for demanding scientific applications.
Technical Advantages:
● Micron-level laminar flow damping
● SMC nanometer-grade high-flow pneumatic actuators
● High-performance pneumatic isolators with a minimum resonance frequency as low as 1 Hz
● Secure connectors on the top of support legs, significantly improving operational safety
● Hybrid chamber design greatly enhances system stability and reduces natural frequency
● Tri-wire pendulum structure maximizes vibration isolation and enables high-precision repositioning after disturbances
● Top-mounted adjustment unit allows easy ±10 mm height tuning
● Industry-leading honeycomb panel welding and bonding technology
