Large pressure ranges and maximum compression ratios are the ideal site of operation for the gas-cooled roots pump OktaLine G. The pumping speed ranges from 250 to 12,000 m3/h, and is suited for low and medium vacuum, such as in the coating and semiconductor industry, in chemical processing and for R&D. Energy efficient drives and the use of frequency converters lowers energy consumption by up to 20%, says the manufacturer. The gear and bearing chambers are completely separate from the gas-pumping chamber, and because the rotors operate without making contact, dry operation is assured. — Pfeiffer Vacuum GmbH, Asslar, Germany
