Scott AV-2000/3000 SCBA Bayonet to Dual 3M Bayonet Adapter ==================================================== This prototype design for a Scott AV-3000 SCBA bayonet to dual 3M bayonet adapter, as requested by firefither32. The goal is to enable cross-compatibility of commercial off the shelf (COTS) filters with other manufacturer's respirators during this PPE shortage. In this case, an adapter for self-contained breathing apparatus used by many fire departments can now be compatible with 3M Filters 2000 Series, 3M Filter 7093, 3M Cartridges 6000 Series or 3M Dual Airline Systems.
