Product Description

This Mason IMF-X-33 spring mount vibration isolator supports lightweight indoor machinery to reduce structurally transmitted noise and vibration. The acoustical spring cups are made of EPDM or Neoprene for a non-skid surface and for minimizing noise and vibration. The cups secure a heavy-duty steel spring for absorbing shock and supporting loads. This mount is a free-standing device for bolt-free application. It works best for indoor applications on lightweight equipment that does not have to be level and does not require bolting. This spring mount vibration isolator is suitable for use on upper building levels on equipment with rotational speeds below 1200 rpm.

Shock and vibration control products (absorbers, mounts, and pads) reduce air and structure-borne dissonance by either blocking or absorbing sound waves, or damping or isolating vibrations that cause them.  Shock absorbers, vibration damping mounts, and vibration damping pads can extend equipment life and help protect work environments, and they are most commonly used in heating, ventilation, and air conditioning (HVAC) systems or in other large machinery operations. Weight distribution determines the number of mounts or pads needed. If evenly distributed, the maximum load capacity per mount or pad should equal the total weight of the machine divided by the number of mounting points available.

Mason Industries manufactures noise reduction, vibration isolation, and seismic restraint control products such as mountings, hangers, and flexible connectors for mechanical equipment. The company, founded in 1958, is headquartered in Hauppauge, NY.
