RHZK6/30 cylinder air respirator self-contained fire respirator silicone rubber mask by Asian features design, DUAL ANTI FOG LENS adopts unique design, anti fog technology and nano processing flow lens demisting design, lens used in surface hardening treatment technique in the world's most advanced. Gas supply valve and mask 360 degrees fast insert, easy to operate, small gas supply valve, with a larger view of the lower view. Carbon fiber cylinder, light weight, Y self locking structure of the cylinder valve, easy to operate. The backplane is really designed according to the figure of the Asian, very good fit, and can change with the movement of the body. The alarm whistle and the pressure gauge alarm whistle are in front of the chest. Users can easily hear the whistle whistle in noisy environment. The pressure gauge is preposed and has luminous display, which is convenient for users to read the pressure value in the cylinder. The design life of 15 years, to ensure the long-term frequent use of reliability and stability, maximum flow is greater than 1000 litres per minute.
RHZK6/30 cylinder air respirator self-contained fire breathing apparatus with a variety of specifications for your choice, according to the needs of different users to mask with a variety of styles, the use of new materials of high quality mask lens, polycarbonate, high transparency, anti fog, alternating with no smell no stimulation and good sealing silicone. The design of positive pressure air respirator is all considered from user convenience. The valve structure is simple and functional, and the pressure in the mask is always greater than the ambient pressure. It is much easier to breathe than the negative pressure respirator. The working time of positive pressure air respirator is usually 70~80 minutes, which is enough for basic disaster relief and disaster relief needs. It is widely used in heavy industries, petrochemical industry, water works, sewage treatment plants, civil aviation and marine industries. The positive pressure air respirator only needs to open the cylinder valve when using, and the high pressure air in the gas cylinder passes through the pressure reducer, the air supply valve and the pipe to enter the mask. At this time, the air pressure has been reduced to normal air pressure.
RHZK6/30 positive pressure self-contained air respirator has a wide range of temperature and can be used normally in the environment of -30 C to 60 degree C. It is made up of 12 parts: face mask, gas cylinder, bottle belt group, shoulder strap, alarm whistle, pressure gauge, cylinder valve, pressure reducer, back support, waist belt group, quick connector and supply valve. The mask is a comprehensive cover designed for Asians with broad vision, fog proof and vertigo, and good air tightness and comfort. Positive pressure air breathing during the use of masks to keep positive pressure, to ensure the safety in the process of the work, can be used with chemical warfare suits to work together, to achieve full protection of staff. Positive pressure air breathing is a self-contained open air respirator, the high-pressure air pressure reducer by medium pressure conduit to supply valve pressure of 0.6 0.9Mpa air supply valve and the mask phase, when the suction supply valve according to the amount of air suction will be output to the wearer for use, will stop the output when worn who breath, exhaled gas through the exhaust valve cover fully vented to the atmosphere.
Attention to the use of self - pressurized self-contained air respirator:
1. firefighters with respiratory diseases should not work as a breathing apparatus.
2. the isolated respirator should not be used immediately after the work of greater labor intensity.
3. the work of a respirator should be required, and two of them should be accompanied by each other to take care of each other.
4. the wearers should observe the indication value of pressure gauge at any time, and evacuate the scene in time according to the distance and time to evacuate to the safe place, or evacuate the scene of the disaster area when the alarm signal is sent out.
5., once entering the air pollution area, the respirator should not be removed. Until the pollution area is removed, the colleague should also pay attention to the fact that the visibility can not be improved. It is considered that the area has no pollution and the respirator should be unloaded.
6. when the valve is opened, to ensure sufficient gas supply, the valve must be unscrewed over 2 laps, or all open.
7. cylinders should be protected from collision, scratching and knocking during the operation, avoiding baking at high temperature and freezing in the sun and drying in the sun. The paint shedding should be repaired in time to prevent rusting of the bottle wall. When it is found to have serious corrosion or damage in the process of use, it should be immediately stopped and tested ahead of time and can be used after being qualified. The service life of ultra high strength steel air cylinder is 12 years.
8. air in the cylinder should not be exhausted all, and the remaining air of no less than 0.05MPa pressure should be left.
