The Parweld XR936A combines the Parweld XR936H Light Reactive Welding Helmet with a clean air respiratory unit to
provide the user with added protection against welding fume,
dust particles and aerosols.
•Clean Air Unit
The Parweld powered air purifying respirator (PAPR) provides a steady
stream of clean air into the welding mask.
The air is fed into the helmet above the welder’s head and exits below the
The air stream combined with the positive pressure created within the
helmet prevents contaminated air entering the breathing zone.
•Portable and Lightweight
The main unit and battery pack are carried by the user on a support
belt around the waist, which is connected to the welding helmet by a
lightweight umbilical hose.
•Adjustable Air Flow
The air flow rate can be adjusted from 150 to 220lpm by means of a push
button panel with led indication. In the event of a flow rate falling below the
minimum required level to give protection the blower unit will automatically
increase the fan speed to compensate. If the minimum flow rate cannot be
achieved then an alarm will sound so that the operator can leave the work
area safely, if the first alarm is ignored the unit will then start to vibrate and
increase the volume of the alarm.
The Li-ion battery pack is rechargeable and will operate from 6 to 15
hours continuously, dependant on operational mode.
•Pre-filters and Filters
The XR936A uses a 2 stage filter process, the main P3 filter gives the
required essential isolation against welding particles, smoke and dust
providing the user with a protection factor of 20.
The standard filter can be complemented with a pre filter which removes
large dust particles and so extends the life of the main filter.
•Conforms to International Standards
The XR936A Air Flow System is independently certified to BS EN 12941
TH2P and CE; NIOSH 42 CPR84N95.
The XR936H Light Reactive Welding and Grinding Helmet is independently
certified to BS EN 379:1994 and BS EN 175:1997:ANSI Z87.1:1989
