Description
Main specifications
Plates
Anthracite painted zinc-plated steel.
Vibration-damper body
NBR rubber, hardness 30, 50, 55, 60 and 80 Shore A.
Standard executions
- AVR-Q:Â square plates with SBR rubber coating.
- AVR-R:Â rectangular plates.
General information
Features and applications
The AVR vibration-damper bases are made up of two steel plates glued on the two faces of a perforated NBR rubber vibration-damper body to ensure better performance.
Generally used for vibrations and shock insulation, where resistance to compression is required.
They are particularly suitable for use with HVAC, pumps, purification and desalination plants, instrumentation panels.
As widely known, vibrations can cause:
- malfunctioning and reduction of the machine lifespan and/or of the adjacent ones;
- noise and thus also damage to human health.
