Type Yx-2-2xx series mounts with two-inch deflection solve critical vibration problems. These mounts are preferred over one inch deflection spring mounts and most rubber mounts due to their higher static deflection. These mounts are normally recommended for building structures where negligible vibration transmission to the building is required. Yx-2-2xx type spring mounts with two-inch deflection are designed for noise and vibration control application in critical areas on concrete. Springs have 50% additional travel to max load as per ASHRAE recommendations.
