Product Description

3M™ Versaflo™ TR-300 Powered Air Purifying Respirator (PAPR) belt-mounted assemblies consist of a motor/blower unit, high-efficiency filter, waist belt, and lithium-ion battery pack. The motor/blower unit supplies filtered air to the headgear via a breathing tube of the ambient air that is drawn through its high-efficiency filter. The blower unit is equipped with automatic flow control; the motor speed is regulated during operation to compensate for the charge state of the battery pack and the increasing level of airflow resistance caused by filter loading. Should the airflow fall below the minimum design flow rate, an audible alarm will sound and the red fan shape LED on the blower unit user interface will flash to warn the user to immediately leave the contaminated environment. Similarly, an audible and visual low battery alarm will activate when the battery pack has approximately 10-15 minutes of charge remaining to warn the user to leave the contaminated area.
