Professional diving equipment with a depth of 120m closed cycle breathing apparatus

According to the needs of different application scenarios, a nationally produced QS-02 back hanging/side hanging circulating respirator has been developed and extensively tested in water tanks, mines, and Nanning Shenglongtan, with a maximum testing depth of 200 meters.

This model has a streamlined structural design, excellent breathing performance and safety, and a unique integrated design that can easily convert the back and side hooks, meeting various diving needs such as special operations, rescue, and salvage.

 

Main features: The mechanical sequence needle valve reliably adjusts the oxygen supply to meet the oxygen demand of divers at different depths, and provides the best oxygen partial pressure. Even if the oxygen partial pressure monitoring system fails, it can still be used safely; The multi-functional monitoring system for oxygen partial pressure monitors oxygen partial pressure in real time and provides diving depth, time, pressure reduction information, electronic compass and vibration alarm functions. It has a user set constant oxygen partial pressure control function and provides support for multi gas pressure reduction programs and mixed gas pressure reduction algorithms. The optimized design of the gas path ensures extremely low respiratory resistance, unique automatic drainage function, and lightweight design (the whole machine includes 18.5kg gas cylinders).
