The New
Positive-Pressure
Injector
Rescue Apparatus

Is the only one on the market which combines the
Safety of the Non=injector type with the Efficiency
of the Injector type.
The combination has been effected by the provision of a small
additional breathing bag on the back of the apparatus, to act
as a pressure equalizer and absolutely prevents the formation
of negative pressure in any part of the apparatus.

IT ALSO ADDS TO THE COMFORT OF THE APPARATUS.
