2019-1-8 · A rule of thumb is to have the pump inlet diameter approximately 1/4 the diameter of the chamber, or greater. Thus, for a 12 inch diameter bell jar, you would use a 4 inch diffusion pump or larger. The time required to reach a given vacuum will be determined by this ratio. The best pump size for the tube making system is a 3 inch air cooled type.
