The 3M Adflo Powered Air Purifying Respirator (PAPR) smart battery charger provides versatility when charging the lithium-ion battery. A wide indoor charging temperature range allows for many working conditions. Whether rapid or maintenance charging is required, an intuitive indicator light system lets a welding professional know the status of the respirator battery with a quick glance. The 3M Adflo Powered Air Purifying Respirator is compatible with all 3M Speedglas welding helmets that require positive air pressure and 3M Versaflo headtops. As one of the most popular respirators of its kind in the world, the 3M Adflo Powered Air Purifying Respirator is designed to provide welders a constant nominal airflow rate of approximately 205 liters per minute, regardless of the battery’s charge or the particle loading of the filter. With the right type of filter and cartridge, the Adflo respirator helps reduce your exposure against both particles and gases—all in one system. The ergonomic leather belt is extra wide around the turbo unit for additional back support.
