3Hz Spring Pad (330 - 2600 daN)

Overview

Thanks to their low suspension frequencies and large deflection, the Vibrostop MOPLA anti-vibration spring support series allows the reduction of vibrations and the elimination of structure-borne noise generated by HVAC systems installed in buildings.

The steel spring permits suspensions to be created with lower frequencies than those normally attainable with rubber anti-vibration mounts, thereby providing more effective isolation, especially for rotary sources with fairly low speeds (below 300 rpm).

The wide variety of models, obtained by combining springs of varying stiffness, allows different spring anti-vibration mounts to be used in relation to the point load, in order to obtain uniform deflections even in machines with unevenly distributed loads.

Features / benefits

• wide range of load capacities, from 330 to 2,600 daN
• low suspension frequency: 3 Hz Natural Frequency, recommended for applications with a forcing frequency 4.5Hz or over
• Static deflection is 27mm with the given loads
• fitted with elastomeric components to eliminate medium/high frequency structure-borne noise
• increased lateral stability thanks to the multi-spring solution
• for installation at the base of the machinery, with the springs compressed
• high resistance to environmental agents
  
• high resistance to oils, corrosion and high temperatures.
  

Technical Information

Commonly Used In: 

• HVAC applications: Air conditioning units, compressors, fridges and fans.
• Pumps
• Generators

Materials

• Spring: C85 steel with epoxy paint
  
• Bases: Elastomer with metal inserts
  
  • The top and bottom of the mount must be fully covered by a smooth, solid, and parallel surfaces

Models, Loading & Dimensions

Note: Loading is for compression.  This mount can tolerate some shear, but is not designed for shear and must not be used in tension.

Lead Time:

With so many varieties of spring mount, these products are kept at component level and are assembled to order.  Therefore, the lead time is typically up to 3 weeks, but that can double during holiday seasons (August and Christmas/NY).
