Thread: Latham supercharger

Tweet

One unusual design is Latham's "Axial Flow" supercharger that resembles a fan compressor from a jet engine. A cylindrical rotor with dozens of little blades spins inside a bladed housing to compress the incoming air in stages. Like a centrifugal supercharger, it runs at high speed (470 percent overdrive) and is not a positive displacement pump but more of a high volume fan with an operating speed around 20,000 rpm! One of it's claimed advantages was a much lower outlet air temperature than a Roots type blower. The Latham supercharger was produced briefly from about 1955 to 1965, but never gained widespread acceptance
