This System Run Times Guide is intended to provide a general understanding of the factors affecting system run times, as
well as run times of example system setups. The term ‘System Run Times’ is meant to convey the approximate time a
complete 3M™ Versaflo™ Powered Air Purifying Respirator (PAPR) system using the TR-600 motor/blower will operate
on a single battery charge before the system automatically shuts down due to insufficient power.
The 3M™ Versaflo™ PAPR TR-600 is a flow controlled system, meaning it is designed to deliver a consistent volume of
airflow throughout its listed operating conditions. It automatically compensates for changes in battery charge status, level of
filter loading, and changes in ambient temperature and pressure. Since these factors affect how hard the PAPR has to work
and thus how much battery power is needed, the system run times can vary significantly. Other key factors that can affect
system run times include: selected airflow setting, the pressure drop of the components making up the entire PAPR system,
and even extreme weather conditions (due to changes in barometric pressure).
The pressure drop of a system is dependent on multiple factors, including the selected headgear, selected breathing tube,
selected filter/cartridge, and pre-filter and spark arrestor use. A system with a higher pressure drop requires the
motor/blower work harder and causes the battery to discharge faster.
System Run Times Under Ideal
System run times displayed in Figure 1 are calculated on a new fully charged battery and clean/unloaded filter in a clean
environment, with a loose-fitting headgear. Battery aging and filter loading will decrease run times.
