KL99 Self-contained SCBA with Carbon Fiber Cylinder
The KL99 SCBA is a positive‑pressure, self‑contained breathing apparatus tailored for firefighters and industrial personnel confronting oxygen-depleted or hazardous atmospheres. It integrates safety, reliability, and ergonomic comfort to meet the stringent performance demands of high-risk operations.
Its flame‑resistant silicone full-face mask boasts an anti-fogified, spherical visor that delivers a 91% field of view, ensuring clarity even in smoke-filled or low-visibility conditions.
A demand valve supplies air at ≥ 500 L/min, maintaining minimal breathing resistance, while the 360° quick‑connect plug ensures rapid, secure mask attachment.
The ergonomically designed backplate and harness, featuring flame‑retardant KEVLAR or Nomex straps and a belt, diffuses weight evenly for increased comfort. The backplate, molded from flame-resistant plastics and carbon fiber, weighs only 0.685 kg.
The pressure reducer provides stable airflow exceeding 1,000 L/min, suited to strenuous breathing demands during emergency response.
Safety is augmented with a luminous, shock‑ and water‑resistant pressure gauge and a loud alarm (≥ 90 dB) that triggers when cylinder pressure drops below 5.5 ± 0.5 MPa.
Available carbon-fiber composite cylinders range from 2 L to 12 L, striking a balance between lightweight construction and extended air supply .
Certified to CE: EN137 standards and offering 60–90 minutes service duration (depending on cylinder size at 30 L/min), the KL99 SCBA is widely deployed in firefighting, petrochemical, maritime, power generation, metallurgy, and military contexts—all validating its reliability under extreme conditions.
