Model CGHK4-L Mobile Long-tube Respirator

The CGHK4-L mobile long-tube respirator is a mobile air supply system primarily used in oxygen-deficient or toxic/hazardous gas environments. This device utilizes a trolley structure to carry high-pressure gas cylinders, providing a single user with 135 minutes of continuous air supply. Unlike traditional self-contained breathing apparatus (SCBA), the extended air supply duration reduces the frequency of work interruptions due to insufficient air. Its technical specifications stipulate a working pressure of 30 MPa, with a pressure regulator stabilizing the output pressure at approximately 0.7 MPa. It is equipped with a 30-meter medium-pressure hose and a 10-meter branch hose. For safety, the product features an alarm pressure point of 5.5±0.5 MPa and a dual pressure relief mechanism with a safety diaphragm and safety valve, ensuring the system operates within the specified pressure range and meets the technical requirements for prolonged confined space work.

Product Advantages

Performance Parameters and Features:
1. Air Supply System Specifications
Duration: Single-person continuous air supply capacity of 135 minutes.
Pressure Range: Rated working pressure 30 MPa, pressure regulator input pressure limit less than 30 MPa, output pressure maintained at 0.7 MPa.
Alarm Setting: Automatic alarm triggered when system pressure drops to 5.5±0.5 MPa.

2. Airflow Control Accuracy
Inhalation Assistance: Dynamic inhalation assistance parameter less than 500 Pa, maintaining respiratory cycle resistance within the set standard.
Safety Pressure Relief: Safety valve opening pressure set at 0.77-1.19 MPa, safety diaphragm burst pressure at 37-45 MPa, controlling overpressure risk through physical structure.

3. Piping Configuration and Structure
Hose Length: Standard configuration includes a 30-meter medium-pressure hose and two 10-meter branch hoses, allowing personnel to move away from the trolley base.
External Dimensions: Product packaging dimensions are 107cm X 69.5cm X 66cm, using a trolley structure to carry the air source.

Product Application Scope:
Confined Space Work: Used in underground pipe corridors, cable trenches, biochemical treatment tanks, and other areas with limited ventilation.
Chemical Plant Maintenance: Used for equipment cleaning and maintenance operations in chemical and pharmaceutical production lines. Environmental Emergency Response: Provides respiratory support to on-site personnel in environments where harmful gas concentrations exceed safe levels.
Long-Distance Operation Requirements: Suitable for working environments where the work location is a significant physical distance from the safe air source area.
