Earthquake countermeasures for manufacturing sites that were given up on: "Air Isolation Device"
Are you experiencing issues with equipment stoppage or production defects due to small earthquakes? During standby, sit down and the seismic isolation device will not disengage! We have achieved a low-floor type that can be easily loaded!
We would like to introduce the "Air Isolation Device," an air-floating seismic isolation device handled by Sansei Co., Ltd. A common drawback of conventional seismic isolation devices is their height, which can affect the equipment mounted on them. However, our product achieves a low-profile design. In vibration tests, we have achieved results where the response acceleration is suppressed to between 20 gal and 30 gal in all cases. 【Features】 ■ Achieves a low-profile design ■ Response acceleration suppressed to between 20 gal and 30 gal in all cases of vibration tests ■ Demonstrates seismic isolation effects from seismic intensity 2 ■ Non-operational state: The device does not shift with small forces due to its seated position ■ Effective in reducing production defects caused by small earthquakes *For more details, please refer to the PDF document or feel free to contact us.
