TECMEN V3 PAPR FreFlow Welding Helmet

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.

Key Features

• Exceptional Optical Clarity (1/1/1/1): Provides distortion-free, true-color vision with excellent contrast and detail.

• Variable Shade Lens: Adjustable DIN 5–8 / 9–13, suitable for a wide range of welding processes.

• Digital Display Controls: Internal digital interface for precise adjustment of shade, sensitivity, and delay time.

• Powerful PAPR Airflow System: Constant airflow between 170–210 L/min, switchable at the press of a button.

• Dual-Purpose Control Button: Controls both helmet power and airflow activation.

• Clean Air Supply: Multi-stage filtration system protects against welding fumes and fine particulates.

• Auto On/Off Function: Intelligent ADF operation for convenience and extended battery life.

• Grind Mode: Enables safe grinding without changing helmets.

• Comfort-Fit Design: Ergonomically balanced for reduced neck strain and long-term wear.

• Comprehensive Protection: Shields face, eyes, and respiratory system from sparks, UV/IR radiation, and airborne contaminants.
