What This Part Is

The Varian VHS-4 is an oil diffusion pump used to achieve high and ultra-high vacuum in semiconductor processing and related vacuum systems. It works by vaporizing pump oil through a series of jets to entrain and compress gas molecules toward the backing pump outlet. Diffusion pumps of this type are commonly found on older CVD, PVD, and research platforms requiring deep vacuum without mechanical moving parts.
