Features
- The STAHLWERK GS20 AIR grinding mask combines eye and face protection with a battery-powered PAPR respiratory protection system and a P3 particle filter of class TH3 P in accordance with EN 12941.
- The fan draws in ambient air, filters out solid and liquid aerosols, dust, and particles, and continuously delivers the filtered air to the grinding mask via a breathing hose.
- The airflow can be adjusted to three levels: ≥170 l/min, ≈200 l/min, or ≈230 l/min.
- The LCD display shows the filter status, airflow level, current airflow data, battery status, and alarm messages.
- If the airflow is insufficient, the system issues an audible, visual, and vibrating warning.
- The 14.8-V Li-ion battery is charged using the included charger. With an airflow of 170 l/min, a new particulate filter, a fully charged battery, and at room temperature, the expected operating time is 10 hours.
- The polycarbonate visor with a wide field of view protects the eyes and face against solid particles with low impact energy up to 120 m/s, in accordance with EN ISO 16321-1.
- The headband, visor distance, and tilt angle can be individually adjusted.
- The grinding mask is designed for medium head sizes, features a face seal, and is ideal for professional use in industry, trades, and DIY.
