KP4519-2 - Lincoln Prism 40-Inch MERV 16 Replacement Filter Cartridge

Breathe Easier with Superior Fume Control

As a welder, the quality of the air in your shop directly impacts your long-term health and daily comfort. The Lincoln Electric KP4519-2 Prism Replacement Filter is designed to keep your shop's fume extraction system running at maximum efficiency, ensuring that smoke and harmful particulates are pulled away from your breathing zone effectively. This 40-inch cartridge is the heart of your Lincoln Prism system, providing industrial-strength filtration that you can rely on shift after shift.

Protection Against Hazardous Fumes

Welding generates a complex mixture of silicates, metallic oxides, and fluorides. If you are welding stainless steel, the risk of Hexavalent Chromium exposure is a serious concern. The KP4519-2 features a MERV 16 Nano rating, which is one of the highest standards for industrial air filtration. This means it captures incredibly small particles—down to the sub-micron level—that standard filters might miss. Whether you are working on heavy structural fabrication, automotive repair, or robotics, this filter ensures that the air returned to the shop environment is clean and safe.

Built for Performance and Longevity

Nobody likes constant maintenance interruptions. This filter uses advanced nanofiber technology that traps dust on the surface rather than letting it clog the inside of the filter material. This allows your Prism system's self-cleaning pulse mechanism to work more effectively, blowing the dust off the filter and into the collection bin. The result? Better suction for longer periods and fewer filter changes. The "White Strap" on the filter is a quick visual indicator that you have the correct 40-inch model for your machine, taking the guesswork out of ordering replacements.

Safe and Clean Change-Outs

Changing a saturated filter can be a messy job, but Lincoln Electric has made it safer and cleaner. Each KP4519-2 comes with a dedicated disposal kit right in the box. This includes a dust mask to protect you during the swap, a pair of gloves to keep your hands clean, and a plastic bag to immediately seal away the old, dirty filter. This simple addition prevents hazardous dust from re-entering the air or getting on your clothes during maintenance, keeping your workspace professional and compliant.
