3M™ Powerflow™ Face-Mounted Powered Air Purifying Respirator 6900PF helps provide respiratory protection against dust, mist, fumes, radionuclides and radon daughters. The respirator is lightweight, face-mounted and uses a high efficiency particulate filter. It is ideal for lead and asbestos. Face-mounted PAPRs may help increase wearer productivity without the need to wear a motorized blower unit at the waist. Powered Air Purifying Respirators are motorized systems powered by a battery pack which draw air through a filter or cartridge to provide respiratory protection to the wearer. The blower unit can be mounted on the waist, face, or head, depending on the system selected. The complete system includes a full facepiece, motor blower unit, battery pack and flow indicator. It is approved for use with a high efficiency particulate filter only.
