Self-Contained Breathing Apparatus (SCBA, RHZK Series)

Positive pressure self-contained breathing apparatus RHZK (RHZK series positive pressure air respirator), strictly manufactured in accordance with GA124-2013 "Positive Pressure Firefighting Air Respirator" and GB16556-2007 "Self-Contained Open-Circuit Compressed Air Respirator" national standards. It is the core respiratory protective equipment for firefighters, rescue personnel, and high-risk workers, and can be bulk purchased to meet the protective needs of various high-risk scenarios. The core function of the product is to provide clean compressed air to users in harsh environments such as toxic and harmful gases, smoke, dust, and oxygen deficiency, isolating external harmful media, ensuring respiratory safety, and effectively solving the pain points of personnel inhaling toxic substances and suffocation due to oxygen deficiency in high-risk environments. It is widely used in emergency rescue and various high-risk operations. The RHZK series positive pressure air respirator consists of core components including a face mask, carbon fiber composite cylinder, pressure reducer, supply valve, back frame, pressure gauge, and residual pressure alarm. Each component is made of high-quality high-strength materials. The cylinder adopts an aluminum liner with full-wrapped carbon fiber composite technology, featuring light weight, high strength, and good safety performance. The face mask features a large-field anti-fog design, fits Asian face shapes, uses non-toxic silicone rubber for the sealing area, providing a tight seal and comfortable wear. The back frame is ergonomically designed with elastic padding to reduce shoulder pressure and make donning easier. The equipment is simple to operate, requiring no complex training. It has a built-in positive pressure protection system that maintains positive pressure inside the mask, effectively preventing harmful gases from entering. The residual pressure alarm automatically sounds when cylinder pressure drops to 5-6 MPa, reminding users to evacuate in time. With complete qualifications, including 3C certification and test reports, it combines portability, safety, and practicality. It is essential respiratory protective equipment for firefighting, chemical, mining, marine, tunnel, and other high-risk workplaces.
