Model CHZK2/6.8F/30 Cart-mounted Self-contained Air Breathing Apparatus

The CHZK2/6.8F/30 trolley-mounted self-contained breathing apparatus is a mobile air supply system, mainly composed of a trolley base, high-pressure cylinder, pressure regulator, long hose, and full face mask. The device operates at a working pressure of 30 MPa, with the pressure regulator reducing the pressure to approximately 0.7 MPa for output. It provides a continuous single-person usage time of 135 minutes. The standard configuration includes a 30m medium-pressure main hose and two 10m branch hoses, allowing for simultaneous use by one or two people. The device integrates physical safety protection mechanisms, including an alarm system at 5.5±0.5 MPa, a safety diaphragm burst pressure of 37-45 MPa, and a safety valve opening pressure of 0.77-1.19 MPa. Dynamic inspiratory assistance is controlled to below 500 Pa. The overall packaged dimensions are 107cm x 69.5cm x 66cm, and the trolley structure facilitates the movement and securing of the air source.

Product Advantages

-

Technical Specifications:
1. Pressure Regulation and Safety Parameters
Multi-stage pressure reduction control: The pressure regulator has an input pressure limit of 30 MPa, and the output pressure is constant at approximately 0.7 MPa.
Physical safety redundancy:  Features a dual pressure relief design with a safety valve (opening at 0.77-1.19 MPa) and a safety diaphragm (bursting at 37-45 MPa).
Pressure warning system: The alarm device activates when the remaining cylinder pressure reaches 5.5±0.5 MPa.

2. Air Supply Indicators and Respiratory Performance
Inspiratory resistance indicator: Dynamic inspiratory assistance is less than 500 Pa, meeting respiratory physiological parameter requirements.
Airflow distribution capability: Long-distance air supply is achieved through the connection of medium-pressure hoses and branch hoses.

3. Structure and Specifications
Mobile structure: Adopts a trolley-mounted design, accommodating a 6.8L cylinder.
Dimensions: The outer packaging dimensions are 107cm x 69.5cm x 66cm, suitable for standard logistics and storage spaces. Application Areas:
Confined Spaces: Suitable for areas with limited air circulation, such as cellars, tunnels, and storage tanks, where carrying compressed air cylinders is not feasible.
Long-Duration Operations: Suitable for environments requiring continuous operation for more than 120 minutes.
Collaborative Work: Using branch conduits, this device allows two operators to work within a 30-40 meter radius around the same air source.
Environmental Limitations: Used in environments where oxygen concentration is below 17% or where concentrations of toxic and harmful gases exceed safe levels, but are not immediately life-threatening.
