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

High-Efficiency Filtration for Industrial Environments

The Lincoln Electric KP4519-2 Filter, MERV 16 Nano, Prism (White Strap) is a premium replacement component engineered to maintain the peak performance of Lincoln Electric's Prism Central Systems and Prism Compact fume extraction units. In industrial settings where air quality is paramount, this 40-inch filter cartridge serves as the primary line of defense against hazardous welding particulates. Rated at MERV 16, this filter is capable of capturing 95% of airborne particles in the 0.3 to 1.0-micron range, making it exceptionally effective against the fine metallic fumes generated during high-amperage welding processes.

Advanced Nanofiber Technology

Unlike traditional commodity filters that rely on depth loading—where particles get trapped deep inside the media and restrict airflow—the KP4519-2 utilizes a specialized Nano fiber layer. This technology promotes surface loading, ensuring that dust and fume particles are captured on the exterior of the filter pleats. This design characteristic is critical for systems utilizing reverse-pulse cleaning mechanisms. Because the particulate cake forms on the surface, the pulse cleaning cycle can easily dislodge the debris, maintaining a lower pressure drop and significantly extending the operational life of the filter. This results in reduced maintenance downtime and lower total cost of ownership for the facility.

System Compatibility and Specifications

This filter is specifically identified by its White Strap, distinguishing it as the 40-inch model compatible with Prism banks requiring high-volume airflow. It is rated for a free air capacity between 2750 CFM and 4000 CFM, ensuring robust suction is maintained across the extraction arm or hood. It is suitable for a wide range of material applications, including mild steel, stainless steel (hexavalent chromium control), and galvanized steel. Additionally, it is approved for use in systems equipped with LimeStone Feeders, providing versatility for complex fabrication setups.

Safety and Compliance

Lincoln Electric prioritizes the safety of maintenance personnel. The KP4519-2 comes complete with a disposal kit, which includes a dust mask, a pair of gloves, and a heavy-duty plastic bag. This ensures that the spent filter, which may be laden with hazardous heavy metals, can be removed and sealed without exposing the technician to secondary contamination. This attention to detail aids facilities in maintaining compliance with OSHA and environmental safety standards.
