./Positive pressure self-contained air respirators are available in a variety of specifications for you to choose from. The masks also have a variety of styles according to different user needs. The mask lenses are made of high-quality new material polycarbonate, which is highly transparent, wear-resistant and anti-fogging. It can be used alternately without Toxic, odorless, non-irritating and good sealing silicone. Positive pressure air respirators are designed with user convenience in mind. The air supply valve has a simple structure and strong functionality. The pressure inside the mask is always greater than the ambient pressure, making breathing much easier than negative pressure respirators. The working time of positive pressure air respirators is generally ~ minutes, which is sufficient for basic rescue and disaster relief needs. It is widely used in heavy industry, petrochemical industry, water plants, sewage treatment plants, civil shipping and other industries. When using a positive pressure air respirator, you only need to open the cylinder valve. The high-pressure air in the cylinder passes through the pressure reducer, air supply valve, and conduit and enters the mask. At this time, the air pressure has been reduced to normal air pressure. The positive pressure air respirator can discharge the exhaled exhaust gas through the exhalation valve. There is no need to process and recycle the exhaled exhaust gas. The structure and usage are relatively simple. The positive pressure air respirator uses a better explosion-proof carbon fiber bottle material, which contains compressed air. It is divided into positive pressure type and external pressure type according to the different pressures inside and outside the mask. It is used to prevent workers from being harmed by thick smoke and toxic gases. .
./When using positive-pressure self-contained air breathing apparatus, you should pay attention to the pressure value shown on the market observation pressure gauge. When the cylinder pressure is lower than the set value, an alarm whistle will sound. At this time, you should leave the dense smoke environment in time. The positive pressure air respirator mask can only be removed after completely leaving the work area. When taking off the mask, you should pull the hook and loop forward with your thumb to loosen the straps. Then insert your thumb between the mask and your chin, and gradually remove it starting from the chin. When taking off the positive pressure air respirator mask, be very careful to prevent inhaling harmful dust and other harmful substances attached to the surface of the mask. In addition to meeting the requirements of the standard, the air respirator completely eliminates visual distortion and deformation on the full-face mask, solving the problem of visual distortion and deformation that exists in most full-face masks in China, and has been well received by the majority of users! In terms of the breathing comfort of the air respirator, it is very comfortable both in the inhalation and exhalation phases. It has a wide applicable temperature range and can be used normally in any environment. ./Cylinder positive pressure air respirator consists of a mask, a gas cylinder, a bottle belt set, a shoulder strap, an alarm whistle, a pressure gauge, a cylinder valve, a pressure reducer, a back support, a belt set, a quick connector, and a supply valve. . The mask is a full-face mask specially designed for Asians. It has a wide field of view, is anti-fog and anti-glare, has good air tightness and is comfortable to wear. Positive pressure air respirators always maintain positive pressure in the mask during use, ensuring safety during work. They can be used together with chemical protective clothing to achieve all-round protection for workers. The positive pressure air respirator is a self-contained open air respirator. The high-pressure air is decompressed by the pressure reducer and transported to the supply valve through the medium-pressure conduit. The supply valve is connected to the mask and is supplied when inhaling. The valve will output an appropriate amount of air for the wearer to use according to the inhalation. When the wearer exhales, the output will stop, and the exhaled air will be discharged to the atmosphere through the exhaust valve on the full-face mask.
./Instructions for use of positive pressure self-contained air respirators. Wearing and use
. When wearing, first disconnect the quick connector (to prevent damage to the full face mask when wearing it), and then place the back on the back of the human body ( The air bottle switch is at the bottom), adjust the shoulder straps and waist belt according to your body shape and tighten them to make them fit, secure and comfortable
Put the long straps on the full-face mask around your neck, and place the full-face mask on it before use chest, so that it can be worn with sucking, and then connect the quick connector
. Put the switch of the supply valve to the off position and turn on the air bottle switch
. Wear a full face mask (no straps required). Take ~ deep breaths and you should feel comfortable. When holding your breath or exhaling, the supply valve should stop supplying air without making a hissing sound. Press the lever of the supply valve with your hand to check whether it opens or closes flexibly. When everything is normal, tighten the straps of the full-face mask to an extent that ensures air tightness, comfort, and no obvious tenderness
After evacuating the scene and reaching a safe place, tighten the full-face mask Loosen the lace clip and take off the full face mask
. Turn off the gas cylinder switch, open the supply valve, unplug the quick connector, and remove the respirator from your body.
