3M™ Adflo™ airflow system - complete

Adflo drive unit with self-regulating QRS breathing hose, airflow indicator, pre-filter, spark arrestor, particle filter, reinforced battery, belt and charger. With the right filter, the Adflo system effectively protects you from both particles and gases.Gas filters are sold as a separate product. Depending on the need, it is possible to replace the particle filter itself or the gas absorber: it is not necessary to replace both components at the same time. Air always flows at a constant nominal rate of 170 liters per minute regardless of the charge level of the accumulator or the number of particles in the filter. For operation in hot and humid conditions, it is possible to increase the airflow to 200 liters per minute.To do this, you only need to press the ON button again.
