Closed circuit breathing system for mine-rescue
HYZ2 Air Respirator For Mining is a positive pressure breathing apparatus which is a device used for mine rescue team members in the rescue work for personal respiratory protection. For mine rescue team members, the device will protect their respiratory organs by making it far from harm poisonous gases. It has the features of safe, reliable, comfortable, easy operation and so on. There are two hours and four hours in two sizes, namely HYZ2/HYZ4.
HYZ2 isolated positive pressure oxygen breathing apparatus, fully absorbed the advantages of similar products at home and abroad and combining the actual situation of our rescue team, the product structure design highlights the small size, light weight, reliable performance, comfortable to wear and easy maintenance, etc. advantages of technology has reached the advanced level. Thus more suitable for use in underground, tunnel, a narrow environment requires the actual use of the ambulance crew. HYZ series of positive pressure oxygen breathing apparatus can be work in any Toxic and anoxic environment.

Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
