AVW-AWR Acoustic Washers-10a

nnnn

Why choose AWR Acoustic Washers?

nnnn

Farrat AWR anti vibration washers are used to isolate bolt

nnnn

through connections by providing a resilient separation of the

nnnn

bolt

nnnn

and the isolated structure where there is no space available for

nnnn

an isolation sleeve

nnnn

Features

nnnn

• Used in conjunction with acoustic / anti vibration pads to

nnnn

provide a degree of vibration isolation across bolt through

nnnn

fixings where are necessary for stability and security.

nnnn

• If an acoustic washer is omitted then the anti vibration

nnnn

pad will be bypassed by the fixing bolt and will therefore

nnnn

offer limited isolation and the vibration can be transmitted

nnnn

through the fixing bolt.

nnnn

• Manufactured for durability, performance and ease of on

nnnn

site installation by vulcanising zinc plated washer to a

nnnn

Chloroprene (Neoprene) acoustic washer and sleeve (bush).

nnnn

• Good oil, chemical and fire resistance.

nnnn

• Operating temperature range from -10 to +90 °C.

nnnn

• Fire rating / building material class: B2

nnnn

Applications

nnnn

Any bolt through connection which requires isolation such as:

nnnn

• Steelwork Isolation in building structures

nnnn
