China Self-Contained Open-Circuit Positive Pressure Air Breathing Apparatus

Self-contained Open-circuit Positive Pressure Air Breathing Apparatus
The self-contained positive pressure air breathing apparatus of KL99 series, which is a kind of isolated protective breathing equipment, provides respiratory protection for users working in oxygen-deficient environment or the environment with toxic and harmful gas. Under normal conditions, the pressure in the respirator mask is a little higher than the pressure in external environment, which can effectively prevent external toxic and harmful gas from intruding into the mask, and guarantee the safety of users.
The product can widely apply to such industries as fire fighting, petroleum, chemistry, metallurgy, power, shipping, military and army, public security, etc.
The air cylinder can be 3L/4.7L/6.8L/9L-carbon fiber composite air cylinder or 6L-steel cylinder (for ship use).
