DATA SHEET AWR Acoustic Washer Steel-reinforced Neoprene Acoustic Washer FARRAT ACOUSTIC WASHER RANGE: Lower Bush Dimension Why choose Farrat AWR Acoustic Washers? AWR    AWTH    AWSTC Increasing Acoustic Performance/Shear Load Capacity Farrat AWR anti-vibration washers are used to isolate bolt-through connections by providing a resilient separation of the bolt and the isolated structure where there is no space available for an isolation sleeve. Features Used in conjunction with acoustic / anti-vibration pads to provide a degree of vibration isolation across bolt-through fixings where they are required for stability and security They can be used in conjunction with other Farrat washers to increase acoustic performance by stacking together Manufactured for durability, performance and ease of on site installation by vulcanising zinc plated washers to a Chloroprene (Neoprene) acoustic washer Good oil, chemical and fire resistance Operating temperature range from -10 to +90ºC Fire rating / building material class: B2 Applications Farrat AWR can be used in any bolt-through connection that requires acoustic isolation such as: Steelwork isolation in building structures Machine / plant holding down bolts Push / pull acoustic connections in conjunction with AWTH Acoustic Washers Facade fixings. Important Note: If an acoustic washer is omitted then the anti-vibration pad will be bypassed by the fixing bolt and will therefore offer limited isolation as the vibration can be transmitted through the fixing bolt.
