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.

Product Features
Dual pump synergy: Roots + rotary vane pump combination, covering a wide vacuum range of 10⁻³~10²Pa, and increasing the instantaneous air extraction volume by 30%.
Full-cycle life guarantee:
Intake air filtration (≥5μm particle interception rate 99%) + buffer tank to reduce foreign matter intrusion;
Temperature control design makes the pump body temperature ≤65℃, extending the life by 50%.
Zero oil return protection: built-in oil blocking structure, the reverse leakage rate of pump oil is ≤0.1% when shutting down, eliminating contamination of the pumped container.
System integration: standard filter and distribution box, support rapid access to the production line, shortening the debugging time by 50%.
