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 does not provide protection against vapors or
gases and is not an intrinsically safe system.
The XR940A belt mounted assemblies consist of a motor/blower unit, high efficiency filter, waist belt,
and lithium ion battery pack. The motor/blower unit draws ambient air through its high efficiency
filter and supplies filtered air to the headgear via a breathing tube. The blower unit is equipped with
automatic flow control; the motor speed is regulated during operation to compensate for the charge
state of the battery pack and the increasing level of airflow resistance caused by filter loading. Should
the airflow fall below the minimum design flow rate, an audible alarm will sound and the red fan shape
LED on the blower unit will flash 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.

WARNING
Properly selected, used, and maintained respirators help protect against certain airborne
contaminants by reducing concentrations in the wear’s breathing zone below the Occupational
Exposure Limit (OEL). It is essential to follow all instructions and government regulations on
the use of this product, including wearing the complete respirator system during all times of
exposure, in order for the product to help protect the wearer.
Misuse of respirators may result in
overexposure to contaminants and lead to sickness or death.
For proper use, see supervisor,
refer to the product User Instructions.
Limitations of Use
Do not wear this respirator system to enter areas where:
•
Atmospheres are oxygen deficient;
•
Contaminant concentrations are unknown;
•
Contaminant concentrations are Immediately Dangerous to Life or Health (IDLH);
•
Contaminant concentrations exceed the maximum use concentration (MUC) determined using the
Assigned Protection Factor (APF) for the specific respirator system or the APF mandated by specific
government standards, whichever is lower.
Immediately exit the contaminated area if any of the low battery or low airflow alarms
activate.
Refer to the User Instructions provided with the applicable headgear and the additional cautions and
limitations under these User Instructions.
The recommended operating altitude range of the XR940A is approximately sea level to 2600 feet
(800 metres).
Do not use in environments subject to high magnetic fields.
