Page: 4 of 25

2.2.5 MM2K PAPR Description, (cont.)

2. The OptimAir MM2K PAPR uses a mask mounted motor/blower to draw air through a cartridge, which removes the particulate contaminant, and provides a constant flow of respirable air directly to the facepiece. The MM2K PAPR is available with High Efficiency Particulate Air (HEPA) cartridge only. The REF will be servicing the motor/blower, facepiece and cartridge. The operating facility will be responsible for servicing the battery, support belt, charger with cable, and power cable. The REF may service all components, if requested.

2.2.6 MM2K PAPR Battery

1. The OptimAir MM2K PAPR uses a nickel metal hydride battery (see Figure 8.3). The battery is encased in a hard plastic case and is water resistant and is designed for easy shower decontamination. The ON/OFF toggle switch is located on the top of the battery. There are loops on the back of the battery case for mounting onto a belt. The battery is charged with a dual rate smart charger.

2. The battery should be stored in temperature range between 50 to 85 degrees Fahrenheit when not in use.

3. The MM2K PAPR battery charger, shown as Figure 8.3, uses one light-emitting diode (LED). When the battery is charging, the LED will be Red.

The battery can stay connected to the charger until it is needed.
