Laboratory test

Anti-vibration floating slab

Silentflex laboratory · El Astillero, Spain

Laboratory test of the spring of a slab specially made to order, for loads above those in the catalogue: it reached 2665 kg with 34 mm of deflection, with loading and unloading, and its natural frequency drops to 2.7 Hz. Catalogue slabs use isolators of up to 700 kg.

Max. load tested
2,665kg
Max. deflection
33.97mm
Lowest natural frequency
2.7Hz

Solid line: loading. Dashed: unloading. The shaded area between them is the energy the mount turns into heat on every cycle — that is its damping.

Description

Silentflex® anti-vibration floating slab is our patented technology (international patent no. PCT/ES2008/000469), which is a floating concrete floor with reliable and high-strength metal containers that allow you to adjust the height of the floor and withstood loads thanks to the springs located inside the containers and filled with damping stainless steel metal cushions for better performance.

Our customised anti-vibration slab can be installed quickly and easily on any surface that needs insulation and can be adapted to any load with special foot screws. The system has an integrated leveling of the entire slab assembly and therefore it can be leveled (raised and lowered) even with the equipment installed on it, which can be attached directly to the floor for greater stability.

This system demonstrates excellent vibration insulation properties: in a noise isolation test measured according to ISO 717-2, the sound insulation was 55 dB, according to independent studies by the Applus laboratory in Cerdanyola del Vallés (Barcelona).

We are convinced of the quality, reliability and high performance of our anti-vibration technology, which is why we provide a 10-year warranty against manufacturing defects of the Silentflex® anti-vibration floating slab.

Key features and benefits of the Silentflex® floating slab:

  • Patented technology (international patent No. PCT/ES2008/000469);
  • 10-year warranty on manufacturing defects;
  • Withstands temperatures from – 70°C to + 300°C;
  • Resistant to aggressive substances: fats, oils, water, etc.;
  • The elastic (damping) element is a high-strength steel spring with an anti-vibration stainless steel metal cushion inside;
  • Stable damping: constant natural frequency over a wide load range;
  • Built-in leveling system for different loads;
  • Easy and quick installation on any surface.
