This spring-Loaded, prestressed, box with a self-frequency close to 3 Hz, is made up of the following elements :

Fabrication:

- 1 high resistance spring, Class C1 according to NFA 47-301, protected by a black epoxy paint baked.

- 2 mechanically welded parts, zinc coated (bi-chromating treatment)

- 2 M10 threaded rods, zinc coated, providing prestressing

- 2 neoprene rubber plates to avoid fixing and improving high frequency of structure-borne sound filtering

Options: 

- Galvanized mechanical parts and stainless steel screws for outdoor mounting.

- "V": lower sole type "VIBRAFRAIN" for soundproofing applications (add 7mm to the height of the supports).

Applications :

- This product is dedicated to the assembly of any material requiring a strong vibratory isolation, active suspension of all kinds of vibrating machinery

- It is especially recommended for the installation of rotating machines of all types: groups generators, air handling units, fans, compressors, pumps.

Performances:

- It is particularly intended for the elastic suspension of piping and machines rotating installed on floating slab

- It makes it possible to obtain high filtering rates, even for machines running at low speed (500 rpm)

- Preloading allows for leveling adjustments without require lifting the entire unit with jacks and draining the installation.
