KP2390-4 - Lincoln Electric X-Tractor Mini & Miniflex Replacement HEPA Filter

High-Performance HEPA Filtration for Welding Safety

The Lincoln Electric KP2390-4 HEPA Filter is an essential maintenance component engineered for the X-Tractor® Mini and Miniflex® portable fume extraction systems. As the welding industry places increasing emphasis on air quality and operator safety, maintaining the efficiency of your fume extraction equipment is paramount. This filter serves as the fourth and final stage in the system's comprehensive filtration process, acting as the ultimate barrier against hazardous airborne contaminants.

Utilizing advanced High Efficiency Particulate Air (HEPA) technology, the KP2390-4 achieves a remarkable filtration efficiency of 99.97%. This level of performance allows it to capture sub-micron particles that may pass through preliminary spark arrestors and pre-filters. By effectively trapping these microscopic particulates, the filter ensures that the air recirculated back into the facility is clean and compliant with safety standards. This is particularly critical when welding materials that generate hazardous fumes, such as stainless steel (hexavalent chromium) or manganese-bearing alloys.

The physical specifications of the filter are precision-molded to fit securely within the X-Tractor Mini and Miniflex housings, measuring approximately 2.44" H x 3.94" W x 8.43" D. A tight seal is crucial to prevent air bypass, ensuring that 100% of the airflow passes through the filtration media. The filter is designed for durability and sustained performance, maintaining airflow until it reaches its maximum holding capacity.

Included with the filter is a thoughtful safety disposal kit, which consists of a dust mask, protective gloves, and a plastic bag. This ensures that maintenance personnel can replace the saturated filter without direct contact with the trapped particulates, adhering to best practices for industrial hygiene. Whether used in robotic cells, heavy fabrication, or maintenance repair operations (MRO), the KP2390-4 is the standard for clean air in portable extraction.
