There are two major variants of diffusion pumps: the standard diffusion pump and the oil vapor booster pump. Both diffusion pumps operate in a similar fashion. Discover how they work in more detail in our blog post, Basic Diffusion Pump Operating Principles.
The essential criteria for choosing an oil vapor booster pump over a standard diffusion pump is when you want to operate with chamber pressures between 1x10-3 mbar (1 micron) and 2x10-2mbar (20 microns). In this pressure range, the oil vapor booster pump outperforms every other vacuum pump on earth by a wide margin.
