HYZ4(C) Isolated Positive Pressure Oxygen Breathing Apparatus(Cabin type)
The product uses a breathing chamber as its gas storage device, leveraging the flexibility of the pleated rubber inside the chamber. As the gas pressure within the chamber fluctuates with each breath, the chamber’s volume expands and contracts, enabling both gas storage and supply functions.

Emergency Equipment
Product description
Product Overview
● The product uses a breathing chamber as its gas storage device, leveraging the flexibility of the pleated rubber inside the chamber. As the gas pressure within the chamber fluctuates with each breath, the chamber’s volume expands and contracts, enabling both gas storage and supply. It is primarily designed for use by mine rescue personnel during emergency response and disaster relief operations.
Product Features
● High stability and strength, making it suitable for scenarios with demanding requirements for equipment stability and reliability, particularly in relatively open environments.
● Features a PA-material housing, anti-fog spherical silicone mask, carbon fiber composite cylinder, integrated pressure regulator, and Blue Ice™ physical cooling technology.
