The HT high throughput series is the pinnacle of our diffusion pump knowledge with technology aimed specifically at industrial users. Edwards diffusion pump is designed for all light and heavy duty industrial applications. The robust construction gives high pumping speed at high pressure. The cast and machined aluminium interior provides consistent performance, while the stainless steel body prevents corrosion and ensures process cleanliness. HT diffusion pumps can get minimum backing pump displacement for maximum through put from 135 m3h-1 to 250 m3h-1 and ultimate vacuum to 5 x 10-7 mbar.
