What is breathing air, what is the function of breathing air, and what is the difference between breathing air and compressed air? This article will take you through it.
1.What is breathing air
Breathing air is not just the ordinary air we breathe. Breathing air actually refers to a special type of air. This kind of air is mainly used by firefighters, divers and medical institutions. Breathing air can come in two forms: one stored in tanks and used by divers and firefighters; the other treated with breathing air purifiers (BAP), commonly found in hospitals, paint booths, sandblasting operations and Dental clinics and other places.
- Application of breathing air
Breathing air purifiers are used in conjunction with low-pressure oil-free compressors to remove carbon monoxide, vapors, oil and other contaminants. The advantage of this type of purifier is that it does not require a storage tank, has no time limit on use, and does not require a high-pressure compressor and casing.
By comparison, a typical tank used for diving or firefighting needs to reach a pressure of 5,000 psi and has time limits and weight issues. To fill these tanks, specialized high-pressure compressors and bottle sealing systems are required, which are often large and expensive.
- The difference between breathing air and compressed air
What is the difference between breathing air and ordinary compressed air? In fact, untreated compressed air contains many contaminants, especially when using lubricated air compressors, so untreated compressed air is not suitable for breathing. But that doesn’t mean you can’t use the same compressor for breathing air and regular compressed air. With an oil-free air compressor and BAP, we can indeed achieve this goal, but the caveat is that the air must be cooled before it is sucked in.
So although there are differences between breathing air and compressed air, they actually have something in common.
