Combining the advanced Navitek S4 auto-darkening welding helmet with the Airkos® powered air filtration unit, this complete system provides reliable protection against welding fumes and airborne particles while delivering outstanding optical clarity for both welding and grinding applications.

Whether you're working in fabrication, manufacturing, maintenance or heavy engineering, the Navitek S4 helps you work safer, longer and more comfortably.

Advanced Welding & Grinding Protection

The Navitek S4 is designed to perform equally well during welding and grinding operations.

The large 1mm polycarbonate grinding visor offers:

• Exceptional visibility
• Full face protection
• EN166B compliance
• EN175B grinding certification

making it one of the most versatile welding and grinding systems available.

True Colour Auto-Darkening Technology

The high-performance auto-darkening filter delivers exceptional optical clarity, helping operators see the weld pool more naturally and accurately.

Features include:

• True Colour technology
• DIN 9–13 variable shade range
• DIN 4 light state
• 93 x 43mm viewing area
• 4 arc sensors
• 0.2 millisecond switching speed

The result is improved weld quality, reduced eye strain and enhanced operator confidence.

Wide 160° Side Vision

Integrated DIN 5 side vision panels dramatically expand the field of view to approximately 160°, helping improve awareness of the surrounding workspace.

Benefits include:

• Improved visibility
• Increased safety
• Better spatial awareness
