Two types of alarms – one audible and one visual – alert user to either a low battery or low flow, such a when a particle filter is fully loaded. LED lights on the battery indicate its charge status on and off the charger.
The 3M Versaflo TR-302N+ PAPR Unit includes only the PAPR blower, filter cover, and air flow indicator. This allows the customer to choose the Versaflo belt, battery, charger, and filter that meets their needs.
