EMFLEX heavy duty restrained spring mounts are used beneath mechanical equipment, either alone or in conjunction with inertia bases, to minimise the transmission of noise and vibration to the building structure. They are designed to ensure that once the vertical load is applied, the horizontal and vertical forces are restrained without affecting the isolation efficiency. They are suitable for mechanical equipment such as chillers, cooling towers, fans, pumps, air handling units, booster sets, etc and offer an economic solution to many vibration problems encountered with plant. Available with a standard deflection of 25mm. The spring will compress proportionally to the actual load applied; ie full compression of 25mm will be achieved when a load is applied which is equal to the load rating. The fixing bolt allows the equipment to be levelled when the spring mounts have been installed.
