= For vibration isolation support of machines that generate large shocks and vibrations = = For vibration isolation tables that do not transmit external vibrations to precision instruments = We offer six types tailored to the load, capable of supporting equipment weighing several tons through combinations. It possesses the characteristics of both vibration-damping rubber and air springs, exhibiting low natural frequency and high damping performance. It can be used across a wide range of fields, from industrial machinery to precision instruments. When used in combination with an automatic level adjuster, it maintains the surface (working area) at a constant height even when the stage moves or the weight of the workpiece changes. We also accept model selection according to the equipment. 【Features】 ○ Can be used for both reducing vibrations on the mounted equipment and for vibration isolation support of machines that generate vibrations ○ Can be integrated as a retrofitted unit for existing equipment without additional processing ○ Even in cases of rapid movement of the internal stage or significant changes in workpiece weight, posture control (in conjunction with the automatic level adjuster) For more details, please contact us or download the catalog.

Vibration isolation tables are used to protect precision instruments from floor vibrations that can adversely affect their accuracy. There are various sources of vibration around us, such as railways, automobiles, construction sites, and machinery within buildings. Microscopes and precision measuring instruments are exposed to these vibrations, leading to issues such as reduced resolution and accuracy. Do you feel that your precision instruments are not performing as specified in the catalog? Blurry observation images and fluctuating measurement values may indicate the impact of vibrations. We can lend you a monitoring device. 【Features】 ○ Compact tabletop size of 300×400mm ○ Compatible with lightweight equipment ○ Compared to our conventional products: Size reduced by 40%, weight reduced by 40-50% For more details, please contact us or download the catalog.

Isn't the noise from the vacuum pump too loud? The soundproof box for vacuum pumps, "SIBc," reduces the noise of the vacuum pump and makes the work environment more comfortable. It lowers the noise level, which can feel loud at A-weighted sound pressure levels of 60-70dB, to a range of 50-60dB that does not interfere with daily life (actual values may vary depending on the surrounding environment and noise source conditions). Let's achieve a quiet environment. 【Features】 ○ Reduces noise to 1/3 to 1/5 (approximately 10-15dB reduction) ○ Easy to assemble, installation completed in just 10 minutes → No special tools required ○ Long-lasting fan forcibly exhausts internal heat ○ Built-in thermometer included as standard ○ Compatible with hoses up to φ50 For more details, please contact us or download the catalog.
