Gas filter SR 315 Class 1 are designed for use with Sundström half masks and full face masks. The filter are of type ABE and provide protection against the following types of gases and vapours:
Type A protects against organic gases and vapours, such as solvents, with boiling points > +65 °C.
Type B protects against inorganic gases and vapours, such as chlorine, hydrogen sulphide and hydrogen cyanide.
Type E protects against acidic gases and vapours, such as sulphur dioxide and hydrogen fluoride.
The gas filter 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.
