Airbag Filters

KnitMesh Technologies knitted mesh airbag filters have been specially developed to prevent incandescent particles from entering or damaging an airbag and to cool the expanding gas following actuation.

Incorporated in airbag inflator systems, KnitMesh airbag filters are uniformly compressed knitted wire mesh elements that trap particulates from the propellant and cool the expanding gas when an airbag is deployed.

These elements are normally manufactured from large diameter stainless steel or carbon steel wire and are suitable for use in driver’s side, passenger’s side and side door inflator designs. Density can be varied according to degree of filtration efficiency required and elements are often highly compressed
