 3M Manufacturer Code: TR 971

The graduated 3M airflow meter is designed to accurately measure the airflow delivered by the Versaflo TR 600 and TR 300 powered air purifying motors. It allows verification that the system operates within the airflow ranges recommended by the manufacturer, ensuring respiratory protection that meets safety requirements. Thanks to its simple and intuitive design, it is easy to use during daily inspections or pre‑work checks. This tool is essential for workers using a powered air system in industrial, pharmaceutical, food processing, or maintenance sectors.

In principle, you should use your RVTR971 airflow indicator to assess the condition of your HEPA filter. However, the TR‑600 motor is equipped with indicators that alert you when your HEPA filter is saturated. If the filter portion of the cartridge is saturated, the cartridge must be replaced. Note that only the HEPA portion of the cartridge is checked by the device.

We suggest consulting the PDF file (in English only) that explains the different markings on the airflow indicator. In summary, it explains that the user must choose a letter corresponding to the ambient temperature and altitude relative to sea level.
