Crystal Lens Technology 2.0
The Helix Pure Air CLT uses Optrel’s Crystal Lens Technology 2.0, which provides an exceptionally bright light state and true-color visibility before, during, and after welding. The CLT system minimizes the green tint common in traditional welding lenses and helps improve weld puddle visibility and overall operator precision.
Panoramic Field of View
The helmet offers a panoramic XXL viewing area that provides up to 6 times the field of vision of traditional welding helmets using standard 100 x 50 mm auto-darkening filters. The patented nose cutout design positions the lens closer to the operator’s eyes for improved peripheral visibility and reduced distortion.
Slide-Up Welding & Grinding System
The integrated slide-up mechanism allows operators to switch between welding and grinding without removing the helmet. This system helps improve workflow efficiency in fabrication shops, field welding, industrial maintenance, and construction applications where frequent task switching is required.
Respiratory Protection Compatibility
The Helix Pure Air CLT is designed for use with the Optrel e3000X PAPR system, delivering filtered airflow directly into the helmet. When connected to the PAPR unit, the system helps reduce exposure to:
Welding fumes
Grinding dust
Aerosols
Smoke particles
Airborne contaminants
The e3000X system is NIOSH-approved and supports TH3-level particle filtration.
