DEZEGA EmSCAPE

Hood 1 has reflective element 2, window 3, half-mask 4. With elastic

straps of the hood, that require no adjustment, half-mask 4 tightly fits

human face. Obturator at the bottom of the hood prevents the suction

of toxic substances under the hood.

Gas mixture in the breathing system of the escape hood circulates

within the pendulum scheme of flow.

During exhale breathing mixture goes through half-mask 4, then

through breathing tube 5 it gets into the regenerative cartridge 8.

Regenerative cartridge absorbs carbon dioxide and moisture from the

gas mixture and releases the volume of oxygen proportional to the

volume of absorbed substances. Breathing mixture from regenerative

cartridge 8 goes to breathing bag 9.

When the user inhales, oxygen-enriched gas mixture from the breathing

bag 9 re-enters the cartridge 8 where it is further purified from carbon

dioxide and returns to the half-mask 4 to the respiratory organs through

the breathing tube 5.

Surplus breathing mixture during exhale leaves the breathing bag 9

through the relief valve 10.

To fill the breathing bag 9 and provide oxygen in the first minutes after

donning the escape hood, activate the starter by pulling the cord up.

After putting on the hood, one can tighten or loosen the adjusting

belts 6 so that the regenerative cartridge 8 does not stretch the

breathing tube 5.

The design of the hood 1 and half mask 4 provides reliable obturation

and no additional external headband straps are necessary.

When the oxygen-containing product in the cartridge absorbs carbon

dioxide and moisture, heat is released. The surface of the cartridge

and the breathing mixture therefore heat as well. This indicates,

that the escape hood is operating correctly, and it should not cause

any anxiety.
