Across industries—from hospital central vacuum systems and CNC routing to pneumatic conveying and milking parlors—the need for reliable vacuum is universal. Atlas Copco delivers this essential utility with unmatched safety, consistency, and cost-efficiency. By connecting with Atlas Copco, you gain more than equipment—you empower your processes, enhance operational control, and boost productivity through intelligent vacuum solutions.
Manufactured in Antwerp, tens of thousands of Atlas Copco claw pumps are already operating quietly and efficiently worldwide. Built for longevity, these pumps maintain a low failure rate even under extreme conditions, ensuring stable performance across diverse industrial environments.
Atlas Copco’s leadership in claw technology stems from deep expertise. The acquisition of Edwards—the pioneer of claw vacuum technology in high-tech electronics—combined with Atlas Copco’s own breakthrough in multi-claw compressor design, has created a powerful synergy. This fusion of knowledge delivers durable, high-efficiency, and cost-effective dry vacuum solutions.
Atlas Copco’s dry claw pumps meet rigorous international standards: ISO 9001 (quality), ISO 14001 (environment), and OHSAS 18001 (safety), all verified by Lloyd’s Register. Backed by a market-leading warranty and a service network spanning 180 countries, they offer round-the-clock assurance that your operations remain in optimal condition.
