The lightweight 3M™ Versaflo™ TR-300 Powered Air Respirator is the key to an easy-to-use, versatile, respirator system for environments with hazardous particles. The 3M™ Versaflo™ powered air turbo is a belt-mounted air purifying device. When combined with one of the 3M approved headtops it forms a power-assisted system for respiratory protection against particles (and nuisance odour where applicable).
The turbo has a slim profile designed for use in tight spaces. The weight of the turbo is only 1095g (including particulate filter, high-capacity battery and standard belt). The curved design of the TR-300 means that it can be worn close to the user’s back, reducing the leverage effect that can cause turbos to feel heavier. The compact shape and air inlet design helps make sitting possible without compromising the airflow intake.
This 3M™ Versaflo TR-315A Starter Kit includes the TR-300 turbo unit, particulate filter, pre-filter, standard belt, high capacity battery pack, battery charger kit self-adjusting breathing tube and airflow indicator.
Sophisticated electronics keep the factory-calibrated airflow at a nominal 190 l/min, eliminating the need for regular calibration by the user. Even as the battery discharges, or the filter becomes loaded with particulates, the unit delivers a steady flow of air. An audible and LED alarm both signal to the user when there is either low battery charge or low airflow – for example, due to a fully-loaded particle filter. LED lights on the battery itself indicate its charge status.
The high-capacity battery runs for at least 10-12 hours Recharging time is less than 3.5 hours.
