Dynaflux UV4509PF Polycarbonate Filter Plate Shade 9

Product Description

The DYNAFLUX UV4509PF is a polycarbonate shaded filter plate designed for use in welding helmets and face shields where optical protection from arc radiation is required. Manufactured from 100% polycarbonate material, this filter lens measures 4.5 inches by 5.25 inches and carries a Shade 9 optical density rating, making it appropriate for light to medium MIG, TIG, and stick welding applications. The lightweight construction, at 0.03 pounds, minimizes added burden on the welder during extended use. This filter plate is typically installed by welders, fabricators, and welding safety equipment technicians performing lens replacement or initial helmet assembly.

Shade 9 filter plates are commonly used in residential and light commercial welding environments where arc flash intensity falls within the lower-to-mid range of welding processes. Typical applications include hobbyist and professional welding shops, fabrication facilities, and maintenance operations requiring face protection during arc welding. The polycarbonate construction provides impact resistance alongside optical filtration, combining mechanical protection with UV and infrared radiation attenuation in a single lens plate.

Key Features

• 100% polycarbonate construction for impact resistance and optical clarity
• Shade 9 optical density rated for light to medium arc welding processes
• Measures 4.5 inches x 5.25 inches for broad helmet and shield compatibility
• Lightweight at 0.03 pounds, minimizing fatigue during extended wear
• Sold individually, allowing single-unit replacement

Compatibility

Designed as a replacement or original-fit filter plate for welding helmets and face shields accepting a 4.5-inch by 5.25-inch lens opening with a Shade 9 optical filter requirement.

Installation Notes

Filter plate replacement should be performed by a qualified welder or safety equipment technician following the helmet or shield manufacturer's lens-change procedure. Ensure the welding power source is de-energized and the work area is clear before handling lens components. Inspect the lens retainer frame for cracks or deformation before installing the new filter plate. Handle the polycarbonate lens by its edges to avoid surface scratching that could impair optical performance.
