Powered Air Purifying Respirator (PAPR) videos


PAPR Information:
Powered Air-Purifying Respirator (PAPR) uses a blower to force the ambient atmosphere through air-purifying cartridges into a respirator (either hood or full-face piece).

The PAPR motor-blower draws surrounding air through the filters which capture the contaminant. Air pressure in the face piece/hood is higher than the surrounding air which is referred to as a positive pressure. This means that if a leak occurs, air will flow from inside the face piece/hood to the outside air.

PAPR Limitations:
PAPRS protect the user, as the battery pack and motor blower unit are fully operational. However, if the battery pack fails or the unit becomes inoperable, this respirator becomes negative-pressure. You must leave the area when the PAPR fails.
