The Navitek shell and all its polycarbonates are certified for grinding with the specific standards EN 166B and EN 175B. The visor is made in perfectly clear 1,0mm thick polycarbonate.

The excellent ergonomics provides perfect protection of the forehead, the ears and the neck.
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 polycarbonate.

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 liftable 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 stepless 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.

When connected to the Airkos, the Navitek S4 helmet provides the filtration of Solid and Liquid Particules (PSL). The flame retardant face seal guarantees limited TH2 inward leakage. The main filter on the Airkos is classified as Re-usable (PRSL), and does not need to be replaced after every shift. The visual and sound alarm will inform the operator when to replace the filter.

The PRSL filter of the Airkos is equipped with a pre-filter, blocking the largest particules and extending the lifecycle of the main filter. As an option, a pre-filter with active charcoals is available.

The Airkos blower unit (PAPR) is approved and certified according to the EN 12941 standard, with and only with the Navitek® headtop.
