Airbag filter 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, knitted
mesh airbag filters use uniformly compressed knitted wire mesh
elements to trap particulates from the propellant and to cool the
expanding gas.
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
