SPRING MOUNTS
Type "Y-4-100" Series
Type "Y-4" series mounts with one inch deflection solves troublesome vibration problems. These mounts are preferred over most
rubber mounts due to the high static deflection of the springs. "Y-4" series spring mounts
are designed for noise and vibration control applications in critical
areas on concrete or wooden floors.
FEATURES:
The mount has a two or three piece cast iron housing for the springs. The mounts are provided with slotted mounting holes on the base for bolting to the floor with a non-skid elastomeric acoustic pad. The elastomeric rubber on the inner housing prevents metal to metal contact and allows the springs to function properly. These mounts have a built in leveling device (external or internal). The springs have 50% additional travel to solid beyond the rated load as per the ASHRAE recommendations. The springs are galvanized, instead of being painted, to prevent rusting in the long run. These spring mounts can also be supplied with flat top or non-skid neoprene top load surfaces in case of internal level adjustment.

APPLICATION:
For all air conditioning equipments such as compressors, air handling units, centrifugal fans, pumps and chillers.
NOTE:
1. Adjust the mounting so that the upper housing clears the lower
housing by at least 1/4" but not more than 1/2".
2. The isolators should be selected in the range of -30% to 25% of
the rated load.
