ABSTRACT:
A device for the recovery of dry chemicals found in powdered form for fire extinguishers utilizing a container having first and second openings. A conduit permits the powder material to enter the container through the first opening. Another conduit permits the material to exit the second opening into the fire extinguisher. Lumping is prevented by the use of screens and the like within the container. As the material flows through the second opening of the container, air in the fire extinguisher is conveyed through the first opening in the container.
