SPRING AND RUBBER MOUNTS

SPRING MOUNTS 2” (50mm.) DEFLECTION

INTENT

   All mechanical equipment, piping and ductwork  shall be mounted on or suspended form vibration isolators to reduce the transmission of vibration and mechanically transmitted sound to the building structure. Vibration isolators shall be selected in accordance with the weight distribution so as to produce reasonably uniform deflections.

SPECIFICATION

    Spring isolators shall be free standing and laterally stable without any housing and complete with a molded neoprene cup or ¼” (6mm) neoprene acoustical friction pad between the base plate and the support. All mountings shall have leveling bolts that must be rigidly bolted to the equipment. Installed and operating heights shall be equal. The ratio of the spring diameter divided by the compressed spring height shall be no less than 0.8 Spring shall have a minimum additional travel to solid equal to 50% of the rated deflection. 

ND : DOUBLE DEFLECTION NEOPRENE MOUNTS

• All mounts are double deflection

• Offer more than three times the deflection of pads

• Prevent noise and high frequency vibration

• Isolate a wide range of equipment

• Supplied with cap screw and washer

• Bottom friction surface makes bolting unnecessary

  in most installations

• Neoprene covering prevents corrosion of steel parts

 

INTENT : The definition of a rubber isolation mounting is any configuration, round, square or rectangular with a known capacity and deflection. Acoustical solutions are in the 6 – 8 Hz frequency range. However, these very same low stress isolators can be stacked with steel shim plates between to achieve lower frequencies for vibration isolation. This grouping is typical of special purpose product.

 

SPECIFICATION : Neoprene mountings shall have a static deflection of 0.35” (9mm) to 0.5” (13mm.). All metal surfaces shall be Neoprene covered to prevent corrosion and have friction pads, both top and bottom. Bolt holes shall be provided on the bottom and a tapped hole with capscrew and washer on top. Mountings shall be Type ND
