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.
