TECMEN V3 PAPR FreFlow Welding Helmet
The TECMEN V3 PAPR FreFlow Welding Helmet is an advanced powered air-purifying respirator (PAPR) system designed for professional welders who demand the highest levels of optical clarity, comfort, and respiratory protection. Featuring a 1/1/1/1 optical class lens and variable shade ADF, it ensures superior visibility and safety during extended welding operations.
Equipped with an intelligent air filtration system, the FreFlow unit delivers a constant, clean airflow directly to the welder’s breathing zone, protecting against fumes, dust, and particulates while maintaining comfort and focus throughout the day.
