Sundström SR597 A1BE2K1 Threaded Filter (Each)

The Sundström SR 597 is a threaded A1BE2K1 gas filter for the SR 500 and SR 500 EX fan units. Its A1 part protects against organic gases and vapours with boiling points above +65 °C, such as solvents; B2 against inorganic gases such as chlorine, hydrogen sulphide and hydrogen cyanide; E2 against acid gases such as sulphur dioxide and hydrogen fluoride; and K1 against ammonia and certain amines, such as ethylene diamine. The fan must always be used with two particle filters or two combined filters.
