837731 – Speedglas Adflo Powered Air Respirator – Heavy-Duty Battery


Product Description

Get effective protection from the respiratory hazards associated with the welding process with 3M™ Adflo™ Powered Air Respirator, 837731. Our Adflo respirator connects directly with any Speedglas Series respiratory welding helmet and can protect users against both particles and gases depending on the filter used. For hotter, more humid working environments, the airflow rate can be increased to 200 litres per minute for optimum user comfort. The Li-ion battery makes the turbo unit almost 20 % lighter in weight, providing better balance and added user comfort for the duration of a shift. The heavy-duty battery is recommended when using the respirator with a gas filter, and in some configurations it is also required to use a breathing tube with silencer (834009). Always verify approved combinations with your Safety Engineer or contact a certified Industrial Hygienist for advice.
