This product is designed as an alternative to traditional positive-pressure firefighting air respirators, offering greater flexibility and ease of use in high-risk environments. Unlike standard air respirators that are heavy and bulky, placing a significant burden on firefighters during rescue operations, this device is lightweight, highly mobile, and provides sealed protection. It’s mainly used for fire escape, emergency rescue, and short-term or repeated repair and maintenance tasks in hazardous environments. Built on the foundation of self-rescue breathing apparatus, it features an enhanced protection level and improved mobility. One of its key advantages is the quick-change oxygen module, which can be replaced in just two seconds — allowing for longer operation time and better maneuverability in emergency situations. The primary oxygen supply is fast and stable, and the dual-form storage bag can be adapted to different scenarios. The main unit is recyclable, making it both cost-effective and eco-friendly. This is an ideal solution for firefighters or emergency responders who need lightweight gear with rapid deployment capability in critical situations.
