Emergency Equipment
Product description
Product Overview
● The product uses an airbag as a gas storage device, leveraging the flexibility of the airbag’s material to adjust its volume based on the internal gas pressure—allowing it to store and release air. It is primarily designed for use by mine rescue personnel during emergency response and disaster relief operations.
Product Features
● Compact in size, lightweight, and highly adaptable, making it ideal for use in confined spaces such as narrow underground mine tunnels—environments where flexibility and maneuverability are essential.
● Features a PA-material housing, anti-fog spherical silicone mask, carbon fiber composite cylinder, integrated pressure regulator, and Blue Ice™ physical cooling technology.
