Weltek Navitek S4 Airfed Welding & Grinding System

Navitek Red Side Vision S4 Airfed Welding & Grinding System

Includes: ADF Visor, Airkos Blower Unit and Storage Carry Bag

20-Point APF Protection 

This airfed system is classified as equivalent to FFP3 and provides protection against Coronavirus. FFP3 provides a 20-points protection factor unlike an FFP2 disposable mask that offers 10-points protection. 

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, 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 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.

All versions of Navitek* S4 are certified and available with the Airkos® respiratory unit for particules filtration
