Range of application
The positive pressure fire air breathing apparatus series products enable firefighters
and emergency rescuers to prevent inhalation of harmful toxic gases, smoke and
harmful pollutants suspended in the air during fire fighting or rescue operations.
Applicable to firefighters or rescue workers in toxic or harmful gas environment,
containing harmful substances such as smoke and oxygen and other environments,
to provide effective respiratory protection for users.

The component of product
Mask
Spherical field of view up to 98%,The flame retardant silicone rubber material is
adopted, and the unique dual anti-fog function of the lens can prevent the fog from
being used for a long time.
Air supply valve
The hand-held air supply valve is small in size and broadens the front field of
vision. The air supply capacity of the air supply valve is greater than 500L/min.
Pressure gauge
The alarm post is hidden in the pressure gauge, which is safer.
Back plate
Made of high strength carbon fiber, with flame retardant and anti - static
function.
Cylinder
Fully carbon fiber wrapped gas cylinder with the aluminum inner tank.
