In areas with interference to the environment such as, e.g. dust, an air
filter is to be used to protect the smoke detection system.
Type LF-AD-x air filter The standard air filter used is the type LF-AD-x, comprising a plastic
housing with two PG29 threaded connections. The multi-layer filter
material absorbs particles which are larger than about 15
μ
m.
The air filter is automatically monitored for dirt (blockage) by the
TITANUS

air flow monitoring arrangement. If the air filters
are dirty, then the filter inserts must be changed by opening the filter
housing.
Special type SF-x filter In extremely dusty areas (e.g. recycling plants) in which the use of an
LF-AD is not sufficient, a special filter must be used. The special filter
safely holds back the dust particles in a heavily polluted atmosphere us-
ing the filter medium. The filter is guaranteed to have an even quality of
dust collection right through to the end of its useful life. Two types of spe-
cial filter are available (type SF-400 and type SF-650), the SF-650 having
a longer useful life because of its larger surface area.
