Dynaflux UV4511PF Filter Plate Shade 11 4.5x5.25 in

Product Description

The DYNAFLUX UV4511PF is a Shade 11 polycarbonate filter plate designed to protect welders' eyes from intense arc radiation, ultraviolet light, and infrared emissions during welding operations. Constructed entirely from 100% polycarbonate, this lens offers impact resistance and optical clarity in a lightweight form factor weighing just 0.03 pounds. Measuring 4.5 inches by 5.25 inches, it fits standard welding helmet and hand shield lens openings of that size. Licensed welding professionals and fabricators install this filter as a consumable replacement component in passive welding hoods and shields.

This filter plate is suited for shielded metal arc welding (SMAW), MIG, and flux-core processes where a Shade 11 darkness level is appropriate for the amperage range being run. It is sold individually and serves as a direct drop-in lens replacement for helmets and shields accepting a 4.5-inch by 5.25-inch filter. Industrial fabrication shops, shipyards, pipe welding crews, and field welders doing heavy plate work are the typical users of this shade level.

Key Features

• Shade 11 optical density blocks arc radiation at appropriate attenuation for mid-to-high amperage welding processes
• 100% polycarbonate construction provides impact resistance and reduced lens weight
• 4.5 inches x 5.25 inches footprint fits standard welding helmet filter openings of that size
• Single-unit packaging allows direct consumable replacement without minimum multi-pack requirement
• Lightweight at 0.03 pounds, minimizing added load to the helmet assembly

Compatibility

Designed as a direct replacement filter plate for passive welding helmets and hand shields with a 4.5-inch by 5.25-inch lens opening requiring a Shade 11 filter.

Installation Notes

Filter plate replacement is performed by welding professionals or qualified safety personnel following the helmet manufacturer's lens-change procedure. Always power down any associated equipment and allow the work area to cool before handling lens components near a welding station. Ensure the replacement lens seats flush and is secured by all retaining clips or frames before returning the helmet to service. Inspect the surrounding gasket or retainer for damage during each lens change.
