The powered air-purifying respirator (PAPR) filters contaminated air and blows it into the face shield through a flexible breathing tube. The respirator system generates a positive air pressure to help prevent contaminants from entering the hood. The system must include and/or be used with the equipment listed below:
·Face shield and headgear system
·Breathing Tube
·Blower assembly with filtration system (spark guard cover, foam prefilter , HEPA filter ), and battery level indicator.
·Belt assembly
·Air flow speed (Low and High) indicator
·Battery charger

The respirator equipment operates at temperatures from -5°to 55°C and provides air flow of 170 LPM (low speed) to 200LPM (high speed) under normal conditions. Battery life is reduced when the unit is used in dirty environment. if the system air flow decreases to an unsafe level, an alarm will sound, the blower vibrates, and the Danger light will flash to warn the users to immediately leave the contaminated area. Use the supplied air flowmeter to determine if the unit is supplying adequate amounts of clean air.
