Structure & Features:

Structure: The Roots-rotary piston vacuum unit is composed of a Roots pump and a rotary piston pump connected in series. It is also equipped with a vacuum gauge sensor, vacuum relay, bellows, vacuum valves, piping, base frame and electric control cabinet

Features: The unit boasts high ultimate vacuum, high pumping speed, low noise, stable operation, compact structure, small footprint, simple operation and convenient maintenance.

Application: As the backing pump of the unit is an oil-sealed mechanical pump, it is not suitable for working conditions where large amounts of water vapor and dust need to be pumped. When fitted with additional auxiliary devices, the unit can also be applied to electronic, electrical, transformer, instrument transformer, coating, smelting, heat treatment, drying, distillation, aerospace and other simulation tests.
