3M Speedglas Welding Helmet 9100 Air (without lens) with 3M Adflo PAPR
Its clear protective visor ( 17 x 10cm) is curved, which allows excellent views up, down, and peripherally. The air duct provides a refreshing airflow across the entire breathing zone and its face seal readily follows the contours of shield and face, along with a high comfort headband and shade 5 side windows.
The new Adflo unit features Lithium-Ion (Li-Ion) batteries, which are more than 40% lighter than the NiMH batteries used in the original model. This lighter battery has the same life-time as its predecessor but benefits from a faster partial charge time.
