Product Description

Introduction of  Portable Oxygen Breathing Apparatus For Firefighters 

HYZ-2/HYZ-4 Isolated Positive Pressure Oxygen Breathing Apparatus is used for personal protection, with reliable performance, comfortable carrying and convenience for maintenance. Main application into coalmine, fire protection, chemical industry, tunnel, scientific research fields where there is noxious & anoxic gas or oxygen insufficient emergency disaster exist.     zmwm17

Respiratory airflow alternately run for the positive and negative pressure, breathing resistance is small, pressure reducer, counterflow.
Assembling of oxygen for quantitative oxygen valve, automatic supply valve, manual supply valves, pressure reducing valves, safety valves, emergency switch focus to design into one, compact, easy disassemble and maintenance. Equipped with a row of saliva in the mouth with the pump, the saliva can always be ruled out.
