Powered Air-Purifying Respirators (PAPR)

· Respiratory protection is now entering the era of PAPR

The PAPR is now attracting attention as next generation Respiratory Protective Equipment (RPE).
Against a backdrop of the compulsory use of respirators by regulations, awareness of occupational safety and health is intensified and the demand for higher performance respirators is increased.
The respirator with a high filtering efficiency of 99.9% by itself, however, does not provide a good enough protection because the protection performance of a respirator should be determined by a total performance as the equation below shows:

Protection performance of a respirator = filtering efficiency ＋ fit between facepiece and face

By supplying purified air into the facepiece, the PAPR can prevent particulates from entering through a gap between the face and the facepiece, thus providing a high protection performance.
It is a “literally” high performance respirator to protect the workers’ health.
