About the PAPR respirator
PAPR respirator（PAPR： Powered Air Purifying Respirator）
To say PAPR respirator, say APR first. APR means air purifier. Doesn't that sound advanced? It's close to you, because your mask, is the Respirator. A Gas Mask is also a Respirator. Gas Mask is the general structure of the“Body + filter/box” form, the mask body provides a sealed environment, and the filter can filter harmful substances.
The only difference between the PAPR respirator and a normal APR is a“P”-- a P for Powered. Unlike SCBA, PAPR does not use high-pressure cylinders. Instead, it uses an electric air supply to reduce the user's respiratory resistance.
I'm sure you've all been feeling this way lately with a mask or mask. You'll find that there's a lot of resistance to breathing, and you'll feel uncomfortable walking a little faster or doing some strenuous activities. If you wear it for a long time, it may cause hypoxia. Those who work in the laboratory need to wear respiratory protective equipment for a long time or do strenuous exercise on top of this during special military and police operations. If ordinary gas masks are used, will appear powerless.
Of course, according to different air supply, some small air volume of the PAPR respirator is simply assisted breathing, and some large air volume can achieve a certain degree of positive pressure protection effect.
That's all there is to know about the PAPR respirator, so in theory, it could be considered one of the“Positive pressure respirators.”. Please feel free to contact us if you need anything.
