The e684 visor shell is designed as a modular platform, fully compatible with the entire range of Optrel Sphere automatic welding filters (ADFs) (e.g. e684, crystal 2.0, vegaview 2.5). This design gives the welder full freedom to choose optics perfectly suited to the specific work being performed, from precision TIG welding to heavy construction work. This makes it possible to upgrade the cartridge itself in the future without having to replace the entire system. An investment in this shell is an investment in a flexible and future-proof system that grows with your needs.

The design of the e684 shell in the PAPR version has been optimized to work perfectly with the e3000X air supply system. Precisely designed air ducts ensure even distribution of clean air inside the visor, creating a comfortable breathing zone without irritating blasts toward the eyes. The balanced design and compatibility with the Optrel headgear provide excellent balance and reduce neck strain during long hours of work. It’s a thoughtful investment in comfort that directly translates into less fatigue and higher concentration.

The included “Parking Buddy” holder is a simple but ingenious accessory that solves the everyday problem of putting down the visor. Attached to the waistband of your pants, it allows you to safely “park” your helmet when not in use, protecting it from drops and scratches. A unique latch securely grips the headgear adjustment knob, freeing your hands and ensuring that your valuable equipment is always close at hand. It’s a small detail that represents an investment in the convenience and longer life of the visor.

Welding fumes are classified by the IARC as a Group 1 carcinogen, and their inhalation leads to irreversible diseases. The e3000X air supply system provides the highest possible level of protection (TH3), filtering out as much as 99.8% of harmful particles, fumes and aerosols. A controlled positive pressure is created inside the visor, effectively isolating the breathing zone from the polluted external environment. This is an absolutely fundamental investment in your own health and ability to perform your profession for years to come.

The e3000X system offers three levels of airflow (170, 210 and 240 l/min), which can be adjusted to suit the intensity of work and environmental conditions. The highest level, 240 l/min, not only delivers the maximum amount of clean air, but also generates a noticeable cooling effect on the face and forehead. This is an invaluable feature when welding at high temperatures or in stuffy, confined spaces. An investment in regulated flow is an investment in thermal comfort, which directly affects productivity and fatigue reduction.

This kit is equipped with the most powerful lithium-ion battery in the Optrel range, which provides up to 18 hours of continuous operation on a single charge (at the lowest flow rate). This performance allows you to work comfortably for two full 8-hour shifts without having to take breaks to charge or change batteries. This eliminates downtime and allows you to fully focus on the task at hand. It’s an investment in operational continuity and maximizing production time.
