The dummy head
General remarks
For optimal results during mask testing, inflate the dummy head to the size of a normal human head
(see images) via the filling hose mounted to the dummy head's base. The filling hose is equipped with
a push-button valve that can be connected to a medium-pressure supply (e.g. the medium-pressure
hose of an SCBA). Inflate the dummy head by pressing the push-button.
The dummy head is
insufficiently inflated.
The dummy head is ideally
shaped for testing masks.
The dummy head is inflated too
much.
CAUTION: Inflating the dummy head too much may damage it.
Taking care of the dummy head
In order to prevent premature wear and tear, protect the dummy head from direct exposure to sunlight
and cover it with a protective hood if it is not used for an extended period of time. Once a week, apply
plenty of silicon spray and let it work into the (uncovered) dummy head overnight.
Article number of silicon spray (500 ml) 1800-015
