In the mid 1930s Mr. F.L. Burt of San Francisco believed the Untied States would benefit from his German-designed filling system. Thus the F.L. Burt Filling Machine Company was founded. As the machines were straightforward, and uncomplicated to use, Mr. Burt chose the name "Simplex" for his machines.
Mr. Burt's top selling machine was a table-top, single-head piston filling machine. Today, this machine, the AS-1, is the cornerstone of the Simplex line. Little has changed on the AS-1, and it is as reliable, accurate and cost effective as it was nearly 50 years ago. There are a few original machines that are still in use today. In 2000, Simplex relocated to a brand new, 13,000 square feet facility in the world famous Napa Valley in California.
