Principle of system operation
When the system is operating according to the instructions, air is introduced to the room
via the air inlet valve and the NBC filter
(2)
. The filtered air is circulated through the room
and creates an overpressure, thus preventing the entry of polluted air through crevices
or concealed openings
When the room is in a state of overpressure, the indicator vane
(7)
spins around. In this
state, it is possible to remain in the room without the personal NBC masks (on condition
that the room is not contaminated by NBC before operating the system). Overpressure
created in the room is not harmful to humans and pets.
The following illustration displays the parts of the system and their location in a
residential safety room:
