Sundstrom ABEK1 Gas filter SR297, Class 1, is designed for use with Sundstrom half masks and full face masks. The filter is of type ABEK and provides protection against the following types of gases:
• Type A protects against organic gases and vapours, such as solvents, with boiling points+65
• 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.
• Type K protects against ammonia and certain amines, such as ethylene diamine. The gas filter can easily be combined with particle filter 210/310 P3 in order to obtain protection also against aerosols (particles), e.g. during spray painting.
