Military issue 3M brand Powered Air Purifying Respirator, from military surplus. These units were part of Air Force Hazmat / Disaster / CBRN disaster response kits and appear to have been very little aside from the occasional drill.

The PAPR powered style respirator has many advantages over the regular type gas mask. The filters mount on the powered blower and it supplies a constant feed of fresh, filtered air to the wearer. They allows the mask itself to be loose fitting and works well even when the wearer is small, a child, or has facial hair that would preclude proper fit of a normal mask. They also are much easier to show an untrained person how to wear. Comfort is much higher, especially in warmer environments and when running or doing strenuous work, and fatigue is much lower allowing the setup to be worn much longer.

These units take the standard 40mm filters and can use 1 filter or multiples, up to 3. 

Each set comes with the mask/hood, air tube, turbo blower with waist belt, pressure test gauge, & instructions.

You will need to provide filters and batteries. Filters and batteries are NOT included.

For filters you these masks take any 40mm size filters. They can be 3M brand filters, military gas mask filters or others, based on your needs. If you wish to use less than 3 filters you will need a 40mm filter plug for each port not used. All of that is easily found here on eBay.

For batteries you will need either 3M part # 520-04-57R01, a single use battery with a 12 hour life, or the 3M BP-15 rechargeable battery with a 8 hour life, that also requires the 3M BC-210 charger. Batteries can be found here on eBay. Some of my customers have also built their own 6v battery packs and power supplies to use more common batteries, this is an option if you have the knowledge and ability. I do NOT offer this service. 

All units are used, may have minor wear or dirt from storage and handling. All units are tested before shipping.
