Materials and Processes

Hood material: Silicone (some early versions contain butyl rubber), non-toxic and resistant to aging, with folded edges and a sealed frame to enhance airtightness 16.

Lenses: Cylindrical optical plastic with a scratch-resistant coating, providing excellent light transmission 26.

Wearing Comfort

Headband-style 3D structure with 6 adjustable headbands to fit different head shapes, reducing pressure. 23.

Air Supply System: Standard configuration includes an air duct and blower (airflow 80 L/min), with active air supply reducing breathing resistance and extending usage time to ≥1 hour. 27.

Functional Components

Communication Device: Built-in exhalation valve ensures voice clarity; maintain valve seal integrity.

Toxic Gas Filter Canister: Filled with activated carbon-catalyst and high-efficiency filter paper, filters toxic gases and particles (except CO).

Drinking Device: Built-in drinking tube allows concealed drinking without removing the gas mask.

Application Areas

Military/Police: Military operations, counter-terrorism actions, civil defense emergency rescue.

Industrial Settings: Chemical industry, metallurgy, shipping, warehouse operations, and nuclear radiation environment protection.
