The JZN-880 Permanent Magnet VFD Energy-Saving Screw Vacuum Pump is a high-efficiency, low-consumption vacuum solution designed for industrial applications, developed with advanced permanent magnet variable frequency drive technology.

Core Advantages:

 1. Unmatched Energy Savings: By automatically adjusting speed to maintain the set vacuum pressure, it delivers over 30% energy savings compared to traditional fixed-speed vacuum pumps. It only delivers peak performance when the process requires it, such as during rapid evacuation cycles or idling phases, drastically cutting unnecessary power consumption.

 2. Reliable & Efficient Core Components:

• Integrated Screw Host: Direct-driven permanent magnet motor eliminates transmission losses, offering high torque, fast response, and meeting IE5 efficiency standards.
• Axial Flow Fan: Low power consumption, fast heat dissipation, stable operation, and eco-friendly performance.
• Soundproof Enclosure: Reduces noise significantly via sound-absorbing foam and metal panels, lowering soundproofing costs for the pump room. All components are accessible for easy inspection and maintenance.
• Integrated VSD Driver: Fully integrated variable frequency drive for plug-and-play installation, with optimized parameters for higher efficiency.
• Microcomputer Controller: Centralized control system that displays real-time operating status, alerts for maintenance needs, and triggers safety shutdowns in case of faults.
• Specialized Inlet Valve: Automatically controls opening to ensure proper oil injection and lubrication, minimizing oil loss.
• Oil-Gas Separator: Advanced design reduces residual oil content to ≤3ppm, with a service interval of up to 5000 hours.
• Air Filter: Patented rotary cantilever design for easy maintenance, high filtration efficiency, and extended service life.

 3. Consistent, Stable Performance: 

With an ultimate vacuum of 30 Pa and a high pumping speed of 14.6 m³/min (876 m³/h), it maintains reliable vacuum conditions for continuous industrial processes, ensuring stable production and reducing maintenance costs.
