RHZK6.8/B Positive Pressure Fire Air Breathing Apparatus 6.8L Carbon Fiber SCBA Fire Rescue Respirator

The RHZK6.8/B Positive Pressure Fire Air Breathing Apparatus is a professional self-contained positive pressure respiratory protection device designed for fire rescue, industrial emergency and hazardous environment operation. Equipped with a high-performance 6.8L carbon fiber composite cylinder, this SCBA (Self Contained Breathing Apparatus) provides stable and long-lasting clean oxygen supply. Adopting advanced positive pressure air supply technology, the internal mask pressure is always higher than external ambient pressure, effectively preventing toxic gas, smoke and harmful dust from invading. Lightweight, high-temperature resistant and explosion-proof, it is widely used in fire fighting, chemical engineering, petroleum, mining, tunnel operation and oxygen-deficient confined space rescue, being essential safety equipment for professional rescue workers.

The RHZK6.8/B positive pressure fire air breathing apparatus is a professional high-standard respiratory protection equipment tailored for fire rescue and industrial hazardous environments. The core air storage cylinder is made of high-quality carbon fiber composite material, which abandons the defects of heavy weight and easy rust of traditional steel cylinders. It has ultra-high pressure resistance, impact resistance and explosion-proof performance, and can withstand 30MPa rated working pressure, ensuring safe storage and stable output of compressed air.

This SCBA adopts mature positive pressure air supply technology. During use, the pressure inside the mask is always maintained at a positive pressure state, which can effectively isolate external toxic smoke, chemical harmful gas, dust and anoxic air, completely solving the protection loopholes of ordinary negative pressure respirators. The built-in precision pressure monitoring system can real-time monitor the residual air volume, and automatically trigger a high-decibel alarm when the air pressure is insufficient, ensuring the safety of rescue personnel.

With 6.8L large capacity design, the total air storage reaches 2040L, which can support about 68 minutes of continuous operation under standard working conditions, fully meeting the time requirements of fire fighting, emergency rescue and equipment detection. The whole machine has excellent environmental adaptability, normal operation in extreme temperature environment from -30℃ to +60℃, with flame retardant, waterproof and anti-aging properties.

The overall structure is ergonomically optimized with flexible adjustable back support and buffer shoulder straps, which can fit the body tightly, disperse bearing pressure, and avoid discomfort during long-term wearing and high-intensity work. It is the designated standard protective equipment for fire brigades, chemical enterprises, petroleum mines, tunnel engineering and other professional fields.
