When comfort is designed into respiratory protection products, workers can focus on the work and not the PPE. The 3M™ Versaflo™ Powered Air Purifying Respirator (PAPR) system tries to do just that engineered for versatility and customization, so safety managers can build the system that works for their employees. Choose from a wide range of headgear, breathing tubes and air sources to customize a PAPR solution that works for your environments. A versatile assembly approved with multiple facepiece, breathing tube, battery, and filter/cartridge options that is designed to meet the needs of a variety of work environments and applications. The PAPR system uses a blower instead of lung power to draw air through the filter. This lets you breathe more naturally and stay cooler in hot, humid conditions. The 3M™ Versaflo™ TR 611 assembly includes motor/blower (TR 602N), standard battery (TR 630), battery charger (641N), length adjusting breathing tube (BT 63), easy clean belt (TR 627), airflow indicator (TR 973), spark arrestor pre filter (TR 662), pre filter (TR 6600), 2 caps and storage plug (BT 953). The TR 611N assembly may be combined with 3M Full Facepiece Reusable Respirators.
