Gas filter SR 217, Class 1, and SR 218 Class 2, are designed for use with Sundström half masks and full face masks.
Both filters are of type A and provide protection against organic gases and vapours, such as solvents, with boiling points > +65 °C.
The gas filters can easily be combined with particle filter SR 510 P3 R in order to obtain protection also against aerosols (particles), e.g. during spray painting.
