Vacuum Pump EDWARDS E2M40/E2M80 Series are air-cooled rotary vane vacuum pumps designed to operate using a two-stage oil-sealed rotary vane system. This configuration ensures high and rapid suction performance while maintaining a quiet operation. The direct-drive mechanism of the vanes contributes to a compact size, low vibration, and efficient moisture removal capability from the production process.
