The Radikal helmet combines a clear and ergonomic undervisor with a flip-up front. This flip_up incorporates the automatic filter and the side visions, and is easily raised thanks to a side trigger and a semi-automatic assistance. The shade adjustment is variable from DIN shade 5 to DIN shade 13. Deactivatable, the Auto-shade Mode allows the automatic selection of a dark shade depending on the welding intensity. The Radikal has an XXL field of vision associated with the side vision in polycarbonate shade DIN 5. The automatic filter is classified 1/1/1/1 in optical quality and has True Colors technology for perfect vision of colors and contrasts. Combined with the Airkos, the Radikal helmet ensures filtration of Solid and Liquid Particles (PRSL), with a TH3 classification of inward leakage. The Airkos has 2 airflows with a side air inlet in the Radikal helmet shell and a double internal air diffuser. Associated with 2 distinct audible alarms, the digital display informs the operator of the level of filter clogging and the battery charge level. Operating on a Lithium-Ion battery, the Radikal Airkos provides 9-10 hours of operating time. Premium bag with reinforcements and interior pockets included.
