CEP932-105-11 - 2x4 Shade 11 Glass Welding Lens Filter Plate

Precision Optical Protection for Industrial Welding

The Generic Lense Filter Plate Shade 11 2X4 is a premium-grade passive welding filter designed for professional industrial applications requiring fixed-shade protection. Manufactured from high-quality, heat-treated glass, this filter plate offers exceptional thermal stability and optical clarity, minimizing distortion often associated with lower-grade plastic alternatives. The heat-treatment process significantly enhances the mechanical strength of the glass, ensuring it meets necessary impact resistance standards for occupational safety while providing a robust barrier against welding spatter and debris.

This specific lens features a Shade 11 darkness rating, which serves as an optimal intermediate level of protection for a wide range of amperage settings in Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), and Gas Tungsten Arc Welding (GTAW). The filter effectively blocks harmful ultraviolet (UV) and infrared (IR) radiation generated during the arc welding process, protecting the operator's vision from actinic keratoconjunctivitis and retinal damage. The glass substrate is inherently resistant to scratching, ensuring a longer service life in abrasive industrial environments compared to polycarbonate lenses.

Dimensionally, the plate adheres to the industry-standard 2-inch by 4-1/4-inch form factor. This universal sizing ensures compatibility with a vast array of passive welding helmets, handheld shields, and goggles utilized in fabrication shops, shipyards, and construction sites. The edges are precision-ground to prevent chipping and to facilitate smooth installation into lens retention systems. For optimal performance and longevity, this filter plate should always be installed behind a clear safety cover lens to protect it from direct spatter impact and pitting.

In MRO (Maintenance, Repair, and Operations) settings, maintaining a stock of reliable passive filter plates is essential for ensuring continuous workflow. The Shade 11 glass lens provides a dependable, fail-safe solution that does not rely on batteries or sensors, making it an indispensable component in any welder's personal protective equipment inventory.
