The Navitek® S4 combines the polyvalent S4 autodarkening filter, with one of the largest clear grinding visors available on the market.
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.
Positionned into the liftable front frame, the S4 autodarkening 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 associated to the Airkos®, the Navitek® S4 helmet provides the filtration of Solid and Liquid Particules (PSL). The bolted and flame retardant face seal guarantees a limited TH2 inward leakage inside the headtop. 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. Cf certificate below :
Completing the alarm for the clogged filter, the filtration unit is also equipped with a distinctive alarm for the battery, informing the operator when the charge is running low.
The Airkos® is delivered with a standard 4-cell Lithium-ion battery. A heavy-duty battery with 6 Lithium-ion cells is also available. When equipped with the standard battery (CR7020), the Airkos® can provide up to 10 hours of operating time (with a new filter and on minimum airflow). Once equipped with the heavy-duty battery (CR7021), the Airkos® offers up to 15 hours, under the same conditions.
According to the welding application, the close environment and the operator’s habits, it is possible to select between 2 airflows on the Airkos®. 180l/m is the minimum airflow. With a simple push on the control knob, the unit increases the airflow to 220l/m.
A very large and padded belt provides an excellent comfort and a perfect support of the blower unit. As options, a padded harness and/or a belt extension are available to complete the existing belt.
