USE
Duration and conditions of use
The exhaustion of gas filters is normally detected by odour on the clean side. The
exhaustion of particle filters or the particle filter section of combination filters is
normally signalled by an increase in flow resistance. The minimum volume flow of
the air is no longer maintained and the alarm signal sounds.
When using filters for radioactive substances, micro-organisms or biochemically-
active substances, the particle filter may only be used once!
