KP3424-6 - Lincoln VIKING PAPR HEPA Filter Replacement (6-Pack)

Precision Filtration for Industrial Safety

The Lincoln Electric KP3424-6 High Efficiency Particulate Filter Assembly is a critical component for the VIKING™ PAPR (Powered Air Purifying Respirator) system, engineered to meet the rigorous demands of industrial welding environments. This package contains six genuine replacement filters, ensuring that safety managers and operators have the necessary consumables to maintain continuous compliance and protection. Manufactured in the United States using an automated assembly line, each filter is constructed to deliver meticulous consistency and reliability, a necessity when dealing with respiratory safety equipment.

Technically, these filters are classified as High Efficiency (HE) particulate filters, capable of removing 99.97% of airborne contaminants down to 0.3 microns in size. This level of filtration is essential for environments where welders are exposed to hazardous metal fumes. The media is NIOSH certified to provide rated protection against a broad spectrum of respirable dusts and metal fume particles. Specific contaminants filtered include, but are not limited to, hexavalent chromium, manganese, iron, zinc oxide, aluminum, nickel, beryllium, cadmium, and lead fumes. By effectively trapping these microscopic particles, the filter prevents them from entering the operator's breathing zone, mitigating long-term health risks associated with heavy metal exposure.

Maintaining the integrity of a PAPR system requires regular filter changes. As the filter loads with particulate matter, the system must work harder to pull air through the media. Replacing the filter with the KP3424-6 ensures that the PAPR unit maintains the required positive pressure and airflow rates (CFM) necessary for the assigned protection factor (APF). These filters are designed for seamless integration with the VIKING PAPR blower unit, allowing for quick, tool-free changeouts that minimize downtime during shifts. The 6-pack configuration is optimized for inventory management in high-volume fabrication shops, ensuring that a fresh filter is always available when the saturation alarm sounds.
