Atlas Copco DSS 65 – outdated model

The DSS 65 is no longer part of the current Atlas Copco range: Atlas Copco took the entire DSS 065–100 scroll range out of its programme and names no successor. Ehrler & Beck advises you on the selection of a current oil-free model. According to the brochure, the DSS 65 reaches a pumping speed of 72 m³/h at 50 Hz and 86 m³/h at 60 Hz and works from atmospheric pressure down to 1.5 mbar(a); the operating instructions state 65 m³/h as the maximum pumping speed and an ultimate pressure of 1.5 ± 0.5 mbar with closed gas ballast. According to the brochure, the rated motor power is 1.5 kW at 50 Hz and 2.2 kW at 60 Hz. The air-cooled pump measures 446 × 488 × 435 mm (L × W × H) and weighs approx. 60 kg according to the operating instructions. The technical data are taken from the brochure “Scroll-Vakuumpumpen DSS” (6996 0270 04) and the operating instructions 9824100082_D from Atlas Copco.
