Full Face Mask
This mask has passed the specified test under CE standards and is proved compatible with the compressed air breathing apparatus.
Three-dimensional spherical. The field vision reachs above 91% with great optical performance.
Excellent optical properties of the mask with high transmittance
The lens has been rigidified and anti-fog treated thus can be without fog on surface for long time.
Asian fit, comfortable donning and good leak tightness
Plug-in structure for quick connect with demand valve
Leak tight mask is made of high quality flame resistant silicon rubber, mouth and nose cover use top silicon rubber, soft and high temperature resistant
Flame resistant head harness and lanyard are easy to wear, safe and comfortable
Highly effective sound transmission speech diaphragm
Inner mask suitable for Asian wearer, decrease the inhaled carbon dioxide content, improve work efficiency
Demand Valve
There is big diaphragm valve inside as the self-balancing system, automatically tracking users’ breathing actions, provide the on-demand supply and ensure that pressure inside the mask higher than external environment.
The square manual turnoff button in front of demand valve can turn off the demand valve against the outputting air flow to stop air supply. And it will automatically starts by the suction at inhalation.
At the bottom is the manual force air supply button, it can automatically supply air when press this button if manual shut-off button fails, secondly, once users do not feel the air supply sufficient and touch this, air flow output will be increased automatically. In addition, it allows the outflux of some not-used-up air pressure in medium pressure hose thus to easily check and disassemble the quick connector.
Streamline design with elegant appearance and no hindrance in vision.
Manual turnoff valve easy to operate..
Comfortable breath with little resistance
Simple operation and convenient use
Ensure large flow and safe air supply by using manual force air flux button
The shell adopts flame retardant and high-strength engineering plastics.
Pressure Reducer
The function of pressure reducer is to reduce the high-pressured air in the air cylinder to be (0.7±0.25) MPa which is the proper functioning pressure of demand valve. No matter how the air pressure in the air cylinder and breathing frequency of users change, pressure reducer always has a stable pressure output.
Output pressure from 90psi to 135 psi (6bar to 9bar), Air flow≥1000L/min
Safety valve will automatically operate while the valve fails. Safety valve can keep the output pressure from 148psi to 225psi (9.9bar to 15bar)
There is a limited flow hole in valve connections, once the pressure gauge or pipe damage, the loss air flow no more than 25L/min
Air cylinder& Air cylinder Valve
The air cylinder is made of high-strength aluminum alloy inner and fully wrapping carbon fiber composite material with high strength and light weight.
The Valve with safe self lock device is to avoid open or close air cylinder valve caused by collision or mishandle in operation. The hand wheel of air cylinder valve rotates anticlockwise to open and on the contrary to close. The air cylinder valve is set with safety membrane with bursting pressure of (37~45) MPa, which can prevent the air cylinder to be transformed and blasted because of too high pressure in the cylinder.
Backboard Components
The backboard assembly mainly composes of backboard, shoulder strap, waist belt, belt buckles, pressure reducer holder and tank band. Shoulder belt, waist belt, pressure reducer and air cylinder are all fixed on the backboard. The backboard is designed in complete accordance with human engineering. Its appearance fully fits human back curves with large contact surface and comfortable wear. The backboard is made by injection molding of flame-resistance engineering plastics and carbon fiber material with high strength, impact resistance, invulnerability and 0.68 kg weight.
The shoulder belt and waist belt are woven by flame retardant, anti-skidding and anti-tearing fabrics and comfortable to be worn. The belt buckles are made flame-resistance materials. The flame resistant feature of shoulder belt, waist belt and belt buckle accords with the requirements of CEstandards. The pressure reducer is fixed on the backboard by wire dowels in the holder and convenient to change.
Back plate designed per ergonomic, lightweight and flexible. It's easily operate with one hand.
Harness connect shoulder strap and belt , can fix the height of the SCBA.
Adjusting the belt can distributed pressure on the shoulders.
Adjusting cylinder strap will firmly fixed on the cylinder on the back.
Pressure Indicator and Alarming Device
The pressure indicator is specified by scale ranged between(0-40)MPa, it is connected with the Reducer through a high pressure hose. The display panel is made of fluorescent material, which enables user to read the figure in darkness. The gauge surface is made of shock-resistant material, protected by rubber cover, waterproof, and dustproof. The high pressure hose is equipped with flow limit device, thus when the pressure gauge is separated from the high pressure hose, the air leaking volume should be no more than 25L/Min while the cylinder pressure is at 20MPa.
The alarming device is on the high pressure hose near the pressure indicator. When cylinder pressure is below(5.5+ 0.5)MPa, the whistle will make about continuous 90d B(A) of noise. Working hours last another 5-10 minutes after warning, if we assume the alarming pressure at 5MPa, cylinder volume 6.8L, user average exhalation at 30L/min, it differs according to cylinder volume at the same time. Under such conditions, user must quit from dangerous place after hearing the alarm and is only allowed to continue to work after replacing with a new cylinder.The Warning Device is fixed on the high pressure pipe near the pressure gage. When the cylinder pressure reduces to (5.5±0.5) MPa, warning whistle will produce the continuous sounds over 90 dB(A). If the calculation is made according to the warning pressure value of 5 MPa, air cylinder volume of 6.8 L and users’ average gas consumption of 30 L/min, it can be used about 5-10 minutes after the warning and the using time of different cylinder volume differs after the warning. Therefore, users shall evacuate from the site after hearing the alarm and can continue to work after changing air cylinder
