【No changes to the drawings required】Over 10,000 installations! With easy construction, this vibration control device can reduce building deformation by approximately "1/2".
The α Damper ExII is a hydraulic damping damper that utilizes principles similar to those of a car's shock absorber. By adopting it in addition to seismic construction methods, it reduces deformation caused by earthquake shaking by approximately half, preventing damage to the structural joints and non-structural components of the house. Unlike brace-type damping devices, it is compact and can be distributed around the perimeter, providing stable damping effects. It reduces building damage from earthquakes by about half and is effective against repeated aftershocks. Our reliable and proven damping technology protects you and your loved ones from earthquakes. = Seven Reasons to Choose 'α Damper ExII' = 1. Can be installed in all types of wooden houses (new, existing, traditional frame, 2x4). 2. Highly durable and maintenance-free, with a reassuring 20-year warranty. 3. Easy installation by one person in about half a day. 4. Effectively absorbs the shaking from repeated earthquakes. 5. Low price that allows for standard adoption by housing brands. 6. Layout planning for the α Damper ExII is provided free of charge by the manufacturer. 7. Over 10,000 units installed, trusted by major builders. *For more details, please download the catalog or feel free to contact us.*
