K4550-3 - Lincoln VIKING 3250D FGS PAPR System with Extended Battery

Advanced Respiratory Protection with Superior Optics

The Lincoln VIKING 3250D FGS PAPR (Powered Air Purifying Respirator) with Extended Battery (K4550-3) is engineered for professional welders who demand the highest levels of safety, clarity, and endurance. This NIOSH 42 CFR Part 84 approved system provides positive pressure air purification, effectively filtering 99.97% of airborne contaminants down to 0.3 microns using a multi-component HEPA filter. It is specifically designed to protect against hexavalent chromium, manganese, zinc oxide, and other hazardous metal fumes commonly found in industrial environments.

Industry-Leading 4C Lens Technology

At the core of the helmet is Lincoln's exclusive 4C Lens Technology, which broadens the visible color spectrum in both light and dark states. Unlike traditional green-tinted lenses, 4C technology delivers a true-color view that reduces eye strain and allows for precise control over the arc and puddle. The lens boasts a perfect 1/1/1/1 optical clarity rating, ensuring zero blurriness, distortion, or shade inconsistency across the massive 12.5 square inch viewing area.

Extended Productivity and Comfort

This model includes the Extended Capacity Lithium Ion Battery, offering up to 16 hours of continuous operation on a single charge—ideal for long shifts or overtime work. The intelligent blower system features an LED display that monitors battery life and filter status, providing both audible and vibratory alerts when attention is needed. Comfort is maximized through a 4-axis adjustable headgear and a padded belt system that evenly distributes weight, reducing operator fatigue during prolonged use.

Integrated Grind Shield and Side Windows

The 3250D FGS shell design integrates a clear grind shield and Shade 5 side windows, significantly expanding peripheral vision and safety. The flip-up mechanism allows operators to switch seamlessly between welding and grinding tasks without removing the helmet, streamlining workflow and maintaining continuous respiratory protection. The external grind control button further enhances ease of use, making this one of the most versatile PAPR systems on the market.
