Constant Pressure Air Outlet DeviceThe SRCPEG constant pressure air outlet device can decompress the high-pressure gas in the bottle through the constant pressure device, and then continuously output it through the medium-pressure tube, allowing you to breathe easily underwater without any effort. | 360° rotatable joint + pressure-resistant and explosion-proof medium pressure pipe360° rotatable joint, equipped with 6.5MM fiber reinforced PU medium pressure tube, soft and resistant to bending, can easily achieve 360° free rotation underwater | Dual filtration systemThrough the adsorption of the double filtration system, harmful substances in the air are intercepted, making the output air cleaner. | 5K explosion-proof valveWhen the gas pressure in the bottle exceeds the pressure of the explosion-proof valve, the pressure will be automatically released to ensure that there are no accidents when using the respirator and you will feel more at ease when using it. |
