1. Excellent Performance

Integrated cylinder structure with higher precision. Proven rotary vane technology ensures more stable performance and greater reliability for the system.

2. Good Heat Dissipation

Air-cooled structure eliminates the need for an external water cooling unit, reducing system installation and maintenance costs.

3. Forced Lubrication

Built-in gear pump and constant pressure oil supply mechanism provide forced lubrication, ensuring stable and reliable operation even under high suction pressure.

4. Multi-Stage Vacuum Design

Meets varying vacuum requirements and water vapor handling capacities for different customers.

5. Dual Anti-Backflow Structure

Automatic anti-backflow valve more reliably protects your vacuum system from oil contamination after shutdown.

6. Fluororubber Seals

Enhances corrosion resistance and addresses oil leakage issues. Optional high-quality oil mist filter effectively filters oil mist, keeping the environment clean.
