Agilent Varian VHS-4 Diffusion High Vacuum Pump - NEW
The VHS-4 Diffusion Pump has a pumping speed of up to 750 l/s and can be ordered with ASA or ISO flanges, standard or extended cold caps, with a variety of voltages. All VHS pumps have a stainless steel pump body and a sight glass/fill and drain assembly for continuous monitoring and easy maintenance of pump fluid. The patented Bulge Contour increases gas capture and maintains lower pressure. Finned boilers increase surface area, prolonging pumping fluid life. This Vapor Jet Pump is a perfect fit for high vacuum and industrial applications such as vacuum furnace, heat treatment, metallizing, and coating processes for optical lenses, electronics and protective film layers.
- Highest pumping speed available
