Helix Pure Air 2.5 Welding Helmet
PAPR Respiratory Protection with Crystal-Clear Visibility
The Optrel Helix Pure Air 2.5 Welding Helmet combines advanced respiratory protection, panoramic visibility, and slide-up convenience into one premium welding system built for demanding industrial environments.
Designed to work with the Optrel e3000X PAPR system, the Helix Pure Air 2.5 delivers clean filtered airflow while providing an ultra-clear 2.5 light state, panoramic XXL field of view, and automatic shade adjustment for professional welding applications.
Respiratory Protection
When combined with the Optrel e3000X blower system, the Helix Pure Air 2.5 provides advanced respiratory protection against welding fumes, smoke, aerosols, and airborne particles while keeping cool filtered air circulating throughout the helmet.
Light State 2.5
The advanced 2.5 light state allows welders to see their workspace clearly between welds without constantly lifting the helmet, improving productivity and reducing fatigue.
Panoramic XXL Field of View
The panoramic lens system provides up to 6.3 times the viewing area of standard welding helmets, improving visibility, positioning, and overall awareness during welding and grinding tasks.
Slide-Up Welding & Grinding System
The integrated slide-up lens design allows users to switch quickly between welding and grinding without removing the helmet.
ShadeTronic® Auto-Darkening Technology
ShadeTronic technology continuously adjusts the shade level automatically based on arc intensity for uninterrupted welding protection and optimal visibility.
FadeTronic® Eye Comfort
FadeTronic technology allows the lens to gradually return to light state after welding, helping reduce eye fatigue during long work shifts.
Multi-Sensor Detection
Five arc sensors provide reliable lens activation even in low-light, obstructed, or difficult welding positions.
True-Color View
True-color optics provide realistic high-contrast color visibility with reduced green tint for improved puddle clarity and weld precision.
IsoFit® Adjustable Headgear
The IsoFit headgear system features fully adjustable 3D fitting for improved comfort, balance, and reduced neck strain during extended use.

Frequently Asked Questions
Does the Helix Pure Air 2.5 include respiratory protection?
The helmet is designed to work with the Optrel e3000X PAPR system for powered air-purifying respiratory protection. Helmet-only versions are also available.
What is the benefit of the 2.5 light state?
A 2.5 light state provides a significantly brighter resting view than traditional welding helmets, making it easier to see your work area between welds.
Is the Helix Pure Air 2.5 good for TIG welding?
Yes. The helmet is designed for TIG, MIG, Stick, plasma cutting, and grinding applications, including low-amp TIG welding environments.
Can you switch between grinding and welding quickly?
Yes. The slide-up lens system allows seamless transitions between welding and grinding without removing the helmet.
What do welders like most about Optrel helmets?
Many welders praise Optrel helmets for their exceptional visibility, true-color optics, panoramic viewing area, and comfort during long shifts.
Are there durability concerns with Optrel helmets?
Some professional welders on Reddit report that while visibility and comfort are excellent, certain Optrel auto-darkening lenses may require warranty replacement over time in heavy industrial use.
