Product Components and Technical Description
Full Face Mask
The full face mask is designed to fit different face shapes and is made from silicone material for a comfortable seal. The visor is manufactured from high-impact, scratch-resistant material and provides a wide field of vision during operation.
Demand Valve
The demand valve can be connected quickly to the mask and is designed to provide stable air supply with low breathing resistance during use.
Steel Cylinder
The compressed air cylinder is made of painted steel with good strength, corrosion resistance, and long service life. The cylinder is rechargeable and intended for repeated professional use under proper maintenance procedures.
Backpack and Harness
The backpack is designed for improved ergonomics and can be adjusted to fit different users. It is made from high-strength material with resistance to chemicals, high temperature, and impact. The reinforced belt and harness help distribute the weight of the apparatus more evenly.
Pressure Reducer and Gauge
The pressure reducer lowers the cylinder’s high-pressure air to a stable medium-pressure level for supply to the demand valve. The pressure gauge allows users to monitor cylinder pressure clearly during operation. When cylinder pressure drops to the 50–60 bar alarm range, the warning whistle emits a continuous alarm to remind the user to leave the hazardous area and replace the cylinder.
Приложения
