255109 - Miller Red Welding Strip Curtain Replacement 300x2mm

Technical Overview of the Miller 255109 Lamella Filter

The Miller 255109 is a specialized replacement component designed for industrial welding safety environments. Identified as a "Filter, Lamella Meter Red 300 x 2," this product is a high-grade PVC strip intended for use in modular welding curtain systems. The designation "Lamella" refers to the individual vertical strips that overlap to form a flexible barrier, allowing personnel and material access while maintaining a protective shield against the hazards of arc welding. This specific unit features a width of 300mm and a thickness of 2mm, which are standard metric dimensions for heavy-duty industrial strip curtains.

The "Red" coloration is not merely aesthetic; it indicates specific optical filtration properties. In welding safety, red transparent curtains are engineered to filter out harmful ultraviolet (UV) and infrared (IR) radiation generated by welding arcs, while still allowing enough visible light transmission for supervisors to monitor the welder safely. The 2mm thickness provides substantial mechanical strength, offering resistance against flying sparks, spatter, and minor physical impacts. This thickness also contributes to the strip's ability to act as a barrier against drafts, dust, and noise, helping to isolate the welding cell from the surrounding facility.

As a Miller OEM product, this lamella strip is manufactured to meet rigorous safety standards. The PVC material is treated to be self-extinguishing, ensuring it does not contribute to fire hazards in the event of direct contact with hot slag. The modular nature of lamella systems means that facility managers can replace individual strips like the 255109 rather than discarding an entire curtain, optimizing maintenance costs and ensuring continuous compliance with workplace safety regulations regarding optical radiation and arc flash protection.
