Low Noise Vertical Compression Mount Rubber Vibration Isolator and Rubber Isolator Mount with 55 Shore A Hardness for HVAC Units

This low noise vertical mount rubber vibration isolator is purpose built for HVAC compressor and fan units where structure-borne noise and vibration travel easily into ductwork and building frames. The vertical mount anti vibration isolator uses a natural rubber body with a rigid steel insert so the unit compresses straight down under load, which delivers a steady vertical isolation path for air handling cabinets, condensing units and rooftop plant. Field measurements typically show a noticeable drop in structure-borne noise once the low noise rubber vibration isolator replaces rigid feet or thin pads.

The elastomer is compounded for a 55 Shore A hardness, a middle softness that gives enough deflection to absorb low frequency compressor vibration without letting the cabinet sag or rock. Because the mount is a vertical compression design, the load always passes through the rubber in the same direction, which keeps the isolation efficiency predictable and the noise reduction stable over the life of the unit. A weather and aging resistant rubber surface keeps the low noise vertical mount working in outdoor air cooled condensers, while the steel insert prevents bolt pull out under repeated start and stop cycles.

HVAC engineers choose a vertical mount rubber vibration isolator when they need a simple, serviceable way to break the vibration path between a machine and the building. This low noise anti vibration isolator installs with a single central bolt, so a compressor or fan unit can be levelled and secured in minutes. The result is quieter occupied spaces, less fatigue cracking in ductwork and hangers, and a smoother running HVAC compressor. If you are designing a new air handling system or retrofitting a noisy rooftop unit, this low noise rubber vibration isolator offers a dependable way to control both vibration and noise.
