Product Information
Description
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 1400 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.
Technical Information
Commonly Used In:
- HVAC applications: Air conditioning units, compressors, fridges
- Pumps
- Generators
Features / benefits
- wide range of load capacities, from 25 to 180 daN
- low suspension natural frequency: 3-6 Hz due to large deflections
- fitted with elastomeric components to eliminate medium/high frequency structure-borne noise
- for installation with compressed springs
- high resistance to environmental agents
- high resistance to oils, corrosion and high temperatures.
Materials
- Spring: C85 steel with epoxy paint
- Caps: Elastomer with metal inserts
- Base: Elastomer with metal inserts
- Note: the same end caps and bases are used for all of the below models
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).
