Advantages of the 2XZ-G Upgraded Model:
1. **Air inlet with anti-backflow oil device** – Prevents oil from returning to the system after shutdown.
2. **Exhaust outlet with oil mist filter** – Reduces oil mist pollution in the indoor environment and minimizes oil loss and refill frequency.
3. **Improved motor** – Provides lower operating temperatures and better stability.
4. **Bracket baffle** – Enhances overall appearance.
5. **More stable pumping speed, better ultimate vacuum level, and lower noise.
6. **Imported fluoroelastomer seals** – Ensures reliable sealing performance.
7. **Forced oil feed system** – Extends the vacuum pump’s service life.
8. **Built-in gas ballast valve structure** – Enhances operational flexibility.
Product Overview
The 2XZ-G series two-stage rotary vane vacuum pump is a newly developed model designed to meet customer needs. Through improvements in the pump’s overall structure, material processing methods, and the addition of a forced oil lubrication control system, a dual anti-backflow oil system at the inlet, and a gas ballast valve, the pump delivers enhanced performance and extended service life.
**Product Features**
– Higher ultimate vacuum, lower noise, and more stable pumping speed.
– Specially designed gas ballast valve reduces the frequency of oil changes.
– Dual anti-backflow oil system prevents oil from returning to the pipeline after shutdown.
– Forced oil supply system ensures lower failure rates.
– Oil mist filter at the exhaust outlet minimizes indoor pollution and oil consumption, making it ideal for laboratory environments.
**Applications**
Suitable for a variety of laboratory equipment, including:
Freeze dryers, rotary evaporators, vacuum drying ovens, centrifugal concentrators, double manifolds, tube furnaces, glove boxes, filtration systems, and more. Can also be used as a backing pump for high-vacuum systems.
