Positive pressure firefighting air respirator full face mask by a large field of view, for the valve, pressure reducer, pressure gauges, residual gas alarm, back care, composite cylinder combination. This product is refined workmanship, quality, reliability, and quality. Will send a signal of greater than 90 dB when the residual gas pressure within the cylinder alarm in less than 5Mpa; products using large field full cover, transparent side windows using the anti-cut surface, internal anti-fog treatment, the use of positive pressure valve for large flow mechanism Warning use of personnel quickly evacuated. Ergonomically designed back care can, with anti-fatigue. Back care and cylinders are designed into a flat triangle, can become independent with the horizontal plane. The product set various functions into one, firefighters and rescue personnel the best personal protective equipment. Products are widely used: fire, chemical, shipbuilding, petroleum, metallurgy, oil platforms. It is the firefighter to provide respiratory protection when rescue personnel working in smoke, steam, hypoxia and other harsh environments personal protective equipment. Quality assurance: from the date of purchase within one year of free maintenance and lifetime maintenance. SCBA Features ● using the new wide field full cover, fog, glare, vision, air tightness, wear comfortable. ● for small valve, gas volume, reliable performance, do not affect vision. ● The backplane is made of carbon fiber composite material, light weight, high strength. Small size and compact ● using the new built-in safety valve pressure reducer ,, reliable performance, without any conditioning, maintenance-free. ● gauge lightweight waterproof loud alarm accurate. ● cylinders with optional pressure display when the cylinder valve closed gas storage bottle can be displayed pressure. ● set back with 6.8L and 9.0L carbon fiber composite cylinder can be arbitrarily replaced. SCBA use positive pressure firefighting air respirator (hereinafter referred to as respirators) is a positive pressure self-contained breathing apparatus, widely used in fire, chemicals, shipbuilding, petroleum, metallurgy, mining, transportation, defense and other department, firefighters or trained personnel and other smoke, gas or oxygen-deficient environment, in fire fighting, disaster relief and rescue work to protect their respiratory personal protective equipment. Range SCBA applicable ● smoke by hypoxia and any gas, smoke, dust contaminated atmosphere. ● Temperature -30 ~ + 60 ℃, relative humidity of 0 to 100% of the atmosphere.
