  Low airflow in your Sentinel Respiratory Product can be due to several reasons. First, the battery may need charging; immediately leave the work area and switch to a fully charged rechargeable battery or new non-rechargeable battery. If you're using the Alkaline Battery Adapter, replace the batteries with five new ones. Second, one or more cartridges may be loaded, in which case you should replace them. Finally, the PAPR blower might be malfunctioning, requiring you to switch to a different blower unit.

  If a continuous low voltage alarm sounds upon blower activation in your Sentinel Respiratory Product, it could be due to a battery issue. If using a rechargeable battery, it may not be charged; leave the work area immediately and switch to a fully charged battery, or recharge the current one. Alternatively, if using the Alkaline Battery Adapter, the alkaline batteries may not be installed properly; replace them with five new Duracell D-cell batteries, ensuring correct polarity during installation.
