Latest Patents

Herrig holds a patent for a "Method and apparatus for determining powder flow rate and transfer." This invention features a pneumatic powder collector designed to assess the transfer efficiency of a powder spray system. The system includes a funnel that directs powder into a sealed collection chamber. A vacuum is created in this chamber by an air flow amplifier, which has an air flow inlet open to the chamber and an exhaust vent open to the atmosphere. Inside the chamber, an air-permeable powder collection bag captures the air-entrained powder drawn into the funnel. The vacuum level is regulated by a pressure regulator, ensuring that it is sufficient to pull all powder sprayed by a spray gun into the chamber without increasing the flow from the gun.
