The 3M Versaflo TR-600 forced airflow system is a belt-mounted air purifying device. When paired with one of 3M's approved headgear, it provides a forced-air respiratory protection system that protects against particles, nuisance odors, gases and vapors. The 3M Versaflo TR-600 forced-air power unit can be used with the following 3M headgear: S-Series, M-Series, HT-622/HT-629/HT-639, HT-707/HT-748/HT-749 and SG9100 Air and SG9100 FX Air. Three user-selectable airflow speeds for improved comfort. Controlled airflow maintained at a constant nominal level even when the battery is discharged or the filter fills with particles. Display shows battery charge status and filter fill level during use. No user calibration of the unit is required. Audible and visual alarms indicate low battery charge and low airflow. Simple, intuitive, easy-to-use two-button operation. Rechargeable lithium-ion battery with LED indicator of charge level. Partial dustproof and partial waterproof (IP54) and short-term immersion in water (IP67) after using cleaning plugs. Two strap options: Easy-to-clean belt with smooth surfaces. Heavy-duty belt for high-temperature or harsh environments (greater durability and spark/flame resistance). Six filter options available: P P plus for nuisance levels* of organic vapors and acid gases, and offering protection against hydrogen fluoride at 10 times the maximum allowable concentration (MEL) A1P ABE1P A2P ABE2K1HgP * nuisance level refers to concentrations below the allowable concentration (MEL).
