Breath-Response Powered-Air Purifying Respirator (PAPR)

For Creation of Easier Breathing… Optimum volume of airflow synchronized with wearer’s inhalation pattern is supplied.

“Easier breathing while wearing a respirator” is always a challenge to respirator manufacturers.
Unlike conventional constant-flow PAPR, breath-response PAPR “BL-Series” resolves difficulty in breathing caused by increase in resistance during exhalation.

The breath-response PAPRs are almost the same in size compared to conventional particulate respirators. Thanks to the Breath-Synchronized Air Flow System (BSFS), the PAPR ensures added protection and natural breathing. As optimum volume of airflow is supplied, replacement schedule of particulate filter becomes longer, and thus, running cost is saved.

Energy-saving, resource-saving
Optimum volume of airflow
Airflow synchronized with breathing pattern saves power consumption, compared to constant airflow. At the same time, excessive accumulation of particulates on filter is prevented, and thus, filter consumption is reduced.

High protection performance (Protection Factor: Category S)
Positive pressure inside the facepiece avoids leakage of particulates.
Pressure inside the facepiece is maintained positive as necessary and sufficient volume of airflow is supplied by fan motor. The positive pressure prevents airborne particulates from entering from the slight opening which may be created between face and the facepiece by accident; and high protection performance can be obtained.

Natural breathing (Comfortable supply of airflow synchronized with breathing pattern).
The breath-response PAPR reduces breathing load.
Fan motor pre-installed in the breath-response PAPR instantaneously starts operating upon inhalation, and airflow supplied is reduced upon exhalation.

The breath-response PAPR warns decrease in pressure inside the facepiece due to decrease in volume of airflow supplied caused by filter clogging.

Enhanced safety can be obtained with the PAPR as the pressure inside the facepiece is maintained positive. PAPRs are regarded as providing high protection performance, as the positive pressure prevents airborne particulates from leaking into the facepiece.

Volume of airflow sufficient to maintain the pressure inside the facepiece positive is still supplied with the residual voltage when the LED starts flashing. However, voltage rapidly decreases after LED starts flashing, resulting in decrease in volume of airflow supplied and decrease in pressure inside the facepiece. In this case, make sure to immediately replace the battery with a new one.
