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.
