An adequate respiratory protection program must include knowledge of hazards, hazard assessment, selection of proper
respiratory protective equipment, instruction and training in the use of equipment, inspection and maintenance of
equipment, and medical surveillance.
•
Do not alter, modify, or substitute any components.
•
Inspect the respirator regularly and maintain it according to the instructions. Repairs must only be made by personnel
authorized by MSA.
•
Verify the contaminant(s) in the environment before entering. Always check that the filter cartridges are appropriate for use
in the environment. A filter cartridge which is not designed for the contaminant present may not provide protection.
•
DO NOT use the filter cartridges if the bag is opened, damaged, or missing. Filter cartridges must be in their original
packaging prior to use in a contaminated environment.
•
DO NOT replace canister/cartridge(s) in a contaminated area. Be sure to follow applicable decontamination procedures.
Failure to follow this warning can cause inhalation of contaminated air, resulting in serious respiratory injury or death.

Description
The OptimAir Mask-Mounted Powered Air-Purifying Respirator (PAPR) from MSA is certified by the National Institute for
Occupational Safety and Health (NIOSH) as an air-purifying device designed only for use in atmospheres
NOT
immediately
dangerous to life or health (IDLH).
The OptimAir MM PAPR is used with the facepiece, which is available in small, medium or large sizes. If needed, Advantage®
4100, Ultravue® and Ultra Elite® Facepieces may be equipped with an integral welder’s lens or clip-on welder’s adapter (only
used with Ultravue Facepieces). See Accessories/ Spare Parts.
The motor-blower and replaceable high-efficiency filter are worn as an assembly attached to the facepiece. The rechargeable
battery pack is worn on the support belt. A power cable connects the belt-mounted battery pack to the motor-blower on the
facepiece. A battery charger is supplied with the respirator.
2.1
Principle of Operation
The motor-blower draws surrounding air through the filter which captures the particulate contaminant. Filtered air passes
through to the facepiece and creates higher pressure than the surrounding atmosphere. Therefore, if a leak occurs, air will flow
from inside the facepiece to the outside air. This is referred to as positive pressure. Air flow also provides wearer comfort. The
rechargeable NiMH battery pack supplies 4.8 volts (nominal) to the motor-blower. The battery pack is replaceable. A fully
charged battery is designed to operate in excess of 8 hours. Then the battery pack can be re-charged in 3 hours using the
standard charger.
The replaceable filter cartridge which traps the particulate contaminant is at least 99.97% efficient against 0.3 micron DOP
aerosol.
