System Description
The PAPR assembly is designed to be used with the Parweld headgear to form a complete approved
respiratory system. When used in accordance with its CE approval, PAPR assemblies help provide
respiratory protection against particulates. The XR940A/XR950A does not provide protection against
vapors or gases and is not an intrinsically safe system.
The belt mounted assemblies consist of a motor/blower unit, high effi ciency fi lter, waist belt, and
lithium ion battery pack. The motor/blower unit draws ambient air through its high effi ciency fi lter and
supplies fi ltered air to the headgear via a breathing tube. The blower unit is equipped with automatic
fl ow control; the motor speed is regulated during operation to compensate for the charge state of the
battery pack and the increasing level of airfl ow resistance caused by fi lter loading. Should the airfl ow
fall below the minimum design fl ow rate, an audible alarm will sound and the red fan shape LED on the
blower unit will fl ash to warn the user to immediately leave the contaminated environment. Similarly
an audible and visual low battery alarm will activate when the battery pack has approximately 10-15
minutes of charge remaining to warn the user to leave the contaminated area.
