MSA BD2100 series of self-contained positive pressure breathing apparatus 15169062093 Tian positive-pressure air positive pressure respirator MSA MSA SCBA air respirator, bd2100 air respirator, air respirator Sperian Bacou SCBA SCBA oxygen breathing apparatus air pump inflatable pump] is an open-style self-supply equipment. Use of the wearer completely dependent on the ambient air, instead of using the high-pressure cylinder filling breathe in air through two vacuum pressure reducer, the input mask for the body to breathe. Exhaled air through the exhalation valve on the mask into the atmosphere. Normal use. Pressure inside the mask is always slightly higher than the external pressure on the environment, which is very effective in preventing the external environment of toxic gases into the mask, which completely protect the safety of the user's breathing. MSA BD02100 series specifically for self-contained breathing apparatus to enter the oxygen, toxic and harmful gases in the operating environment of people. To provide effective respiratory protection. The products are widely used in fire, metallurgy, chemical, oil, electricity, shipping, mining, medical and many other industries and fields. 
 First, the product features 
 Products meet the public security fire GA124-2004, GB16556-2007 standard; 
 With 2L/3L/4.7L/6.8L/9.0L/2X6.8L specifications carbon fiber composite cylinders and other configurations; 
 Available ranging from 30 minutes to 120 minutes of gas supply time; 
 Gas cylinder valve hand wheel for the lateral design, ergonomic design principles; 
 Flame retardant back rack and strap, fully adapt to a variety of harsh environments; 
 Shoulder strap has a special reflective film, so the operator can easily be in the dark to search for companions, so that the greatest degree of protection operation and help the team work together; 
 Walk through the supply pipe from the shoulder strap can be more securely fixed and protected; 
 Button chest with a unique plug design will carry the apparatus more stable; 
 Two kinds of belt tightening design: horizontal or lateral (with national utility model patent), fully embodies the "people-oriented design"; 
 Regulator small size, traffic flow; 
 Easy operation: regulator and mask for the quick jack-type connection, one-handed operation; 
 Masks wide field of vision in particular, fit closely with the Asian face, wearing comfort, scratch-resistant lenses non-cross-section design. So that the wearer's line of sight from any angle without distortion; 
 There are many different styles and materials to choose from face masks; 
 Can quickly configure multiple extensions, links his rescue, alarm, and external gas source extended switching; 
 In line with European EN136, EN137 standard. 
 Second, the cylinder: 
 U.S. production of carbon fiber composite bottle, the overall style aluminum liner, anti-corrosion, engage in impact; 
 Working pressure of 30MPa, hydraulic test pressure of 50MPa, burst pressure greater than 120MPa; 
 Tank Pressure table, ready to provide air pressure value, convenient check and maintenance; 
 Lateral cylinder valve design, easy operation; 
 Red bottle valve rotation, color, bright eye-catching; 
 Cylinders in line with HSE-AL-FW2 Europe or the U.S. DOT E-10945 standards. 
 Third, the chest pressure gauge: 
 Waterproof design to prevent moisture from entering the pressure gauge operating in the water inside; 
 Fluorescent design work in a dark environment can be clearly observed values; 
 Red alert zone, clear and easy to see; 
 Excellent seismic performance, able to cope with a variety of harsh operating environment; 
 Wide range of designs to meet the needs of a variety of design working pressure. 
 Fourth, the regulator: 
 MSA Germany were imported products; 
 The output of the regulator valve is in the air again after decompression to the pressure of gas through the mask, the pressure slightly higher than atmospheric pressure, the mask always maintain a slight positive pressure; 
 Moment of maximum gas capacity 500L/min; 
 High-pressure valve small, simple structure, easy operation, the operating switch is the only side of the red button, a total of three locations: the outer buttons to work in the state; the middle off; hold down the bypass state is - At this point in order to 240L/min constant gas pressure regulating valve; 
 Dynamic respiratory resistance: In 40X2.5L/min respiration, the inspiratory resistance of 90 ~ 115Pa, expiratory resistance of 650 ~ 670Pa; in 25X2L/min respiration, the inspiratory resistance of 160 ~ 190Pa, expiratory resistance 620 ~ 650Pa. 
 Fifth, strap and chest strap: 
 The use of flame-retardant polyester material and resist harsh operating environment; 
 With optional heat reflective, dark in the car can easily be found; 
 Generous cushion design back by feeling more casual; 
 Chest with a unique design, carrying respirators more stable. 
 Six belt: 
 Generous cushion design, so bear who feel soft and comfortable;
