Respirator for Particulate Environments XR940A

XR940A supplies clean, filtered air to the welder. The blower unit has an electronic control unit that constantly monitors and adjusts the fan to ensure a minimum of 170nl/ min air flow. The same system provides alarms which are visual, audible and vibrate for blocked filters and low battery condition. The battery life is normally more than 11 hours on low setting and 9 hours on high setting, but the condition of the filter can affect this. The welding helmet has a multi adjustable head band with enhanced support to spread the load evenly on the welder’s head. The unit sits comfortably at the base of the back supported by a belt and shoulder straps. The unit uses a P3 Particulate main filter combined with a carbon odour filter and a mesh spark trap, all of which are user replaceable. The unit is suitable for use in areas without a restricted oxygen supply. The TH3P filter has a protection factor of 50 and the lifetime of the filter is dependent upon local fume levels. XR940A is a battery powered air purifying respirator for protection against dust and particles.
