KP4519-3 - Lincoln Prism 40-Inch MERV 16 PTFE Replacement Filter (Red Strap)

Advanced Filtration for Industrial Cutting Systems

The Lincoln Electric KP4519-3 is a premium replacement filter cartridge engineered specifically for the Prism Central Systems and Prism Compact units. Distinguished by its "Red Strap" identifier, this filter is optimized for the rigorous demands of thermal cutting applications, including plasma and oxy-fuel cutting tables where particulate loading is significantly higher than standard welding operations. The cartridge features a 40-inch length and is constructed from high-quality Polytetrafluoroethylene (PTFE) media.

Technical Superiority of PTFE
Unlike standard cellulose or blended media filters that rely on depth loading, the KP4519-3 utilizes surface-loading PTFE technology. This membrane acts as a barrier, trapping sub-micron particles on the surface rather than allowing them to penetrate the filter substrate. This characteristic is critical for systems utilizing back-pulse cleaning mechanisms. The dust cake releases far more efficiently from the slick PTFE surface during a cleaning cycle, maintaining a lower pressure drop over the life of the filter and ensuring consistent airflow between 2750 and 4000 CFM.

MERV 16 Efficiency
With a MERV 16 rating, this filter offers hospital-grade filtration efficiency, capturing 95% or more of particles in the 0.3 to 1.0-micron range. This level of filtration is essential for maintaining regulatory compliance and protecting facility air quality when dealing with fine metallic fumes and hazardous byproducts generated during heavy fabrication and cutting processes.

Complete Maintenance Solution
Lincoln Electric prioritizes operator safety during maintenance cycles. The KP4519-3 package includes not just the filter element, but a complete disposal kit comprising a dust mask, protective gloves, and a heavy-duty plastic bag. This ensures that maintenance personnel can remove and dispose of the saturated filter with minimal exposure to captured hazardous particulates.
