It is a pneumatic system to feed gunpowder automatically. POLVERE must be installed in an area different from that where the ammunition is loaded, and connected to the machine through copper pipes. The tank in a POLVERE can contain up to 17.5 kg of propellant and each single dose that is sent to the loading machine is about 100g, thus ensuring total safety within the loading area. It can be connected to Kameleon, Extrema or Metallica loading machines.
