Edwards E2M28 Vacuum Pump Ultimate Vacuum 1 x 10-3 mbar / 7.5 x 10-4 Torr Inlet Connection NW25 Flange Displacement 38.9 m3h-1 / 22.3 ft 3min-1 Features Quiet operation ensures a more comfortable working environment, ideal for spaces where noise reduction is crucial. Features a compact, freestanding design for flexible use across various settings without requiring additional support. Proven reliable performance in a wide range of laboratory and industrial applications, showcasing its versatility and dependability. Incorporates a gas ballast valve, essential for effectively pumping vapor without condensation inside the vacuum pump. Built-in motor protection systems include cooling by an external fan and thermal overload protection that automatically resets. Maintenance is simplified with an O-ring sealed sight glass for easy monitoring of oil levels and conditions at a glance. Designed for effortless oil changes, featuring an oil drain port at the end of the oil box for convenient oil removal. Facilitates easy oil top-ups through a large filling port and a recessed top, minimizing spills and maintenance time. The EM range of oil‑sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single‑phase or three‑phase (four pole) motor.
