2 INTRODUCTION
These user instructions must be followed when using and operating the ESAB PAPR
System. Failure to follow these instructions may void the warranty of the product(s). Refer to
the terms of your purchase contract in respect of the product(s) for the specific details of the
warranty.
2.1 Overview
The ESAB PAPR System is a respiratory protective system that circulates over-pressured air
in the hood. The belt-mounted blower unit delivers air through a filter and via an air hose into
the headpiece. The supply of filtered air creates positive pressure inside of the headpiece,
which prevents the external contaminated air from entering the breathing zone.
2.2 Equipment
The ESAB PAPR System is supplied with:
• Blower unit including battery, P R SL particle filter and pre-filter
• Belt
• Air hose
• Air flow indicator
• Battery charger
• Instructions manual
2.3 Prerequisites
Use the ESAB PAPR System during welding in unconfined spaces, strictly in accordance
with this Instruction manual and the instructions supplied with the corresponding helmets.
Do not use the unit:
• When the blower unit is switched off. When the blower unit is switched off, little or no
respiratory protection is to be expected. Rapid buildup of carbon dioxide and depletion
of oxygen may occur in the head unit.
• In an atmosphere that poses an immediate health or hygiene hazard and/or has less
than 19.5% oxygen content, or contains unknown substances.
• In confined spaces or unventilated areas such as tanks, pipes and canals.
• Near flames and/or sparks.
• In areas with danger of explosion.
• In areas with high winds.
• If the blower unit malfunctions.
Make sure moving parts are not blocked in their movement.
Do not modify or alter the unit or the particle filter in any way.
Protect the unit from ingress of water or other liquids, in particular the motor and fan, the filter
and the battery.
Make sure that the headpiece fits perfectly. The efficiency of the system is only sufficient in
this case. The protective factor of the complete system is reduced if the seal of the
headpiece is not fitted properly, for example if long hair or facial hair is extending into the seal
line.
Correct respiratory protection will not be provided if any part of the equipment is modified in
any way.
Position the blower unit in a way that minimises the risk of the head unit hose becoming
caught up during use. Filters must be attached to the blower unit, and not directly to the
headpiece.
