Product Description

The AT Type Damping Spring Vibration Isolator is designed to reduce vibration and noise transmission from HVAC equipment and mechanical systems. It features a combined spring and damping structure, providing stable performance, low natural frequency, and effective vibration isolation for fans, duct systems, air handling units, and other equipment.

With its open-frame design, the isolator offers high flexibility, reliable stability, and convenient installation. It can be installed directly under the equipment base, and the unit may also be pre-fixed to the foundation with anchor bolts where required. A rubber anti-slip pad is bonded to the steel base to further improve damping performance and installation stability.

This type of vibration isolator is widely used in commercial and industrial HVAC applications where efficient control of structure-borne vibration is essential.
