EXTRA AIR CONNECTION
Some models are equipped with an extra air connection which can be used to:
. Connect to a chemical suit ventilation system
. Connect a rescue hose between two apparatuses
. Connect an extra mask
. Connect the resuscitation mask Revitox
. Feed the apparatus from an external air source
When taking air from the apparatus, point 1-4 above, the air consumption increases
and the duration of the apparatus decreases.
A special female coupling with a non-return valve opener must be used when taking
air from the apparatus, point 1-4 above. This device opens the non-return valve in the
male connection on the apparatus.
ATTENTION! WHEN FEEDING THE APPARATUS FROM AN EXTERNAL AIR SOURCE, THIS KIND OF FEMALE COUPLING MUST
NOT BE USED. IN THIS APPLICATION THE NONRETURN VALVE IN THE MALE CONNECTION MUST BE ABLE TO CLOSE IN
CASE OF DISRUPTION IN AIR SUPPLY FROM THE EXTERNAL SOURCE.
