HYZ4 self-contained positive pressure compressed oxygen breathing apparatus

HYZ series breathing apparatus is used in the contaminated or oxygen-deficient atmosphere, such as mine fire fighting and so on

HYZ series breathing apparatus is a closed-circuit SCBA used in the contaminated or oxygen-deficient atmosphere, such as mine, fire fighting, chemical industry, petroleum and tunnel and so on. It provides long-time breath for the workers to deal with an emergency and provide disaster relief. It adopts positive pressure principle to supply oxygen, which makes the pressure in the facemask exceed the atmospheric pressure, so it can efficiently stop harmful gas outside from flowing into the facemask, which assure rescues corps safety.

Features:Logical structure design, comfortable and reliableLogical casing design, crush-proof, good impermeability, safe and stableHYZ4 cooling canister chamber equips with drainage, which protects against the breathing system resistance.Excellent cooling performance, light and easy to carryAdjustable constant flow unit: Users can adjust the oxygen supply constant amount according to their needs. The supply is stable, clear and long lasting.Self-supplement unit: supplement oxygen in time, safer and save more oxygen.Facemask is equipped with quality speaking unit and drainage , more convenient and user friendly.
