The Navitek® S4 combines the polyvalent S4 auto darkening filter, with one of the largest clear grinding visors available on the market.
The Navitek® shell and all its poly-carbonates are certified for grinding with the specific standards EN 166B and EN 175B. The visor is made in perfectly clear 1,0mm thick poly-carbonate.
The excellent ergonomics provides perfect protection of the forehead, the ears and the neck, while keeping the weight at 581g.
This high comfort level can be advanced once equipped with side vision in shade DIN 5: the Navitek® S4 then provides a 160° vision to the welder, for improved safety and advanced comfort. These side vision are made out of transparent shade DIN 5 poly-carbonate.
The Navitek® S4 is equipped with the longitudinal headgear with 4 settings: height, width, angle, and longitudinal adjustment for welders operating with corrective glasses.
Positioned into the lift able front frame, the S4 auto darkening filter offers a 93x43mm viewing area with a perfect vision of the fusion during welding thanks to excellent 1/1/1/2 optical classes.
The 4 arc sensors are associated to a very fast switching speed of 0,2ms for a flawless detection of the welding arc, with all welding processes: electrodes, MIG/MAG, TIG.
Inside step less knobs allow the welder to select the welding shade (from DIN 9 to DIN 13), to adapt the sensitivity of the 4 arc sensors, and to adjust the delay according to the welding application.
All versions of Navitek* S4 are certified and available with the Airkos® respiratory unit for particles filtration.
