KL99 Self-contained SCBA with Carbon Fiber Cylinder
The KL99 SCBA is a positive pressure self-contained breathing apparatus meticulously engineered for firefighters and industrial workers operating in oxygen-deficient or hazardous gas environments. This advanced respiratory protection system combines reliability, safety, and user comfort to meet the stringent demands of high-risk applications.
At the heart of the system is a full face mask crafted from flame-resistant silicone, designed for a secure and comfortable fit across diverse facial shapes and sizes. The mask features a spherical anti-fog visor that offers an expansive 91% field of view, ensuring clear visibility even in the most challenging conditions such as smoke-filled or low-light environments.
Air supply is managed through a demand valve capable of delivering ≥500 liters per minute with minimal breathing resistance, enhancing user comfort during strenuous activity. The valve incorporates a 360-degree quick-connect plug system, allowing rapid and secure attachment to the facepiece for efficient donning and doffing.
The ergonomically designed backplate assembly includes flame-retardant shoulder straps and a waist belt made from high-strength materials like KEVLAR or Nomex. These components work together to evenly distribute the apparatus’s weight, reducing wearer fatigue during extended use. The integrated pressure reducer ensures stable airflow with a capacity exceeding 1000 liters per minute, catering to the intense breathing demands of emergency operations.
Safety is further reinforced by a luminous pressure gauge and an audible alarm that activates when cylinder pressure falls below the critical threshold of 5.5 ± 0.5 MPa, providing timely alerts to the user. The SCBA is compatible with a range of carbon fiber composite air cylinders, available in multiple capacities from 2 to 12 liters, delivering a balance of lightweight durability and extended breathing duration.
Designed for versatility, the KL99 SCBA is widely deployed across firefighting, petrochemical, maritime, power generation, metallurgical, and military sectors. It offers dependable, long-lasting respiratory protection in extreme conditions, empowering personnel to perform safely and effectively in the most demanding environments.
