The VEAT-008 Roots rotary vane unit adopts a modular combination of "Z-type Roots pump (main pump) + X-type single-stage rotary vane pump (forestage pump)", integrated with air intake filtration and intelligent electrical control unit, covering a wide vacuum range of 10⁻³~10²Pa, with an instantaneous air extraction volume increased by 30%. It is suitable for vacuum drying, smelting, impregnation and other processes, and solves the pain points of traditional pumps such as "insufficient pumping speed, pump oil backflow, and temperature rise overload", helping the production line to operate efficiently and stably.
