MSA Optimair Powered Air Purifying Respirator

The PAPR filters from ambient air and provides a constant flow
of respirable air to the Advantage 3100 Facepiece. The maskmounted motor/blower has a low profile design that enhances
user maneuverability and simplifies decontamination. The
PAPR includes a small, lightweight, water-resistant nickel metal
hydride (NiMH) battery pack that will operate for eight hours
of continuous use. The standard Dual-Rate Battery Charger will
recharge a fully discharged battery in less than three hours.
