RHZK6.8/A Self-contained Air Breathing Apparatus

The RHZK6.8/A self-contained breathing apparatus is an industry-standard self-contained open-circuit respiratory protection device. With a 6.8L cylinder volume and 2040L air storage capacity.

It achieves a balanced combination of endurance and portability among similar products. Its operating temperature range covers extreme environments from -30 to 60℃, and at a rated working pressure of 30MPa, the air supply flow is ≥1000L/min.  

Coupled with a low inhalation resistance design of ≤500Pa, it offers smoother breathing than conventional models.

The product optimizes endurance for different work intensities, providing 70 minutes for light work, 45 minutes for moderate work, and 30 minutes for high-intensity work, meeting diverse scenario needs.

The overall weight of 11.3kg ensures protective performance while reducing the burden of prolonged wear.

Product Advantages

-

Advantages:
Comfortable Breathing: Inhalation resistance ≤500Pa, exhalation resistance is optimized according to breathing frequency, ensuring smooth airflow and reducing respiratory fatigue.
Safety Warning: A high-volume alarm device of ≥90db and a precise alarm pressure of 5.5±0.5MPa provide timely warnings of remaining air volume, ensuring safe evacuation.

Structural Design Features:
Ergonomic Backplate: Designed according to Asian body curves, the weight is evenly distributed, resulting in no significant pressure during prolonged wear.
Efficient Air Supply System: The pressure reducer provides stable output, the air supply valve responds quickly, and the air supply flow of ≥1000L/min meets the needs of rapid breathing.
Reliable Sealing Protection: The static pressure in the mask cavity is reasonably controlled, ensuring excellent airtightness and effectively isolating toxic gases and dust.
Convenient Operation Design: The cylinder valve has a ratchet anti-reverse device to prevent accidental closing, and the pressure gauge has a luminous function for clear readings in dim environments. Applicable Scenarios:
Firefighting: Suitable for various fire scenes, providing protection against dense smoke, toxic fumes, and oxygen-deficient environments, ensuring the safety of firefighting operations.
Emergency Rescue: Provides respiratory protection for rescue personnel in hazardous scenarios such as chemical leaks, underground spaces, and mine collapses.
Industrial Operations: Suitable for industries such as petrochemicals, metallurgy, and warehousing, for use in confined spaces or environments with harmful gases.
Emergency Preparedness: Meets the temporary respiratory protection needs in scenarios such as power repair and laboratory emergency response.
