Description
Product Overview
If you're running a plant where air demand swings throughout the day, this 100HP PM VSD two-stage screw air compressor was built with that exact problem in mind. Jinjing designed this 75kW unit to deliver up to 830 CFM at 116 PSI while keeping power draw tightly matched to what your production floor actually needs. Compared with a conventional single-stage fixed-speed machine, the two-stage compression combined with permanent magnet variable speed control cuts energy consumption by more than 32%. That number isn't a lab figure, it comes from real operating data across installations where load profiles change hour by hour.
Advantages
Two-Stage PM VSD Technology That Actually Pays for Itself
The permanent magnet motor and variable frequency drive work together as one system. When your air consumption drops, the motor slows down instead of running unloaded and burning electricity for nothing. On a typical factory schedule with fluctuating demand, this 100HP PM VSD screw air compressor saves over 32% in energy costs compared with a fixed-speed unit of the same size. The two-stage airend also runs at lower compression ratios and cooler temperatures, which means less wear on the rotor and longer oil life. Most customers see the price difference recovered within 12 to 24 months, sometimes faster if they run two shifts.
High-Precision Airend and Imported Core Components
We use high-precision two-stage screw airends from internationally known brands. The rotors are precision-machined and dynamically balanced before assembly, so vibration stays low and performance stays consistent over years of operation. Over 80% of the core components are imported, including airends, bearings, and control elements from Germany, Switzerland, and Italy. That matters when you're running 24/7 and can't afford downtime.
1:1 Direct Drive, No Belts to Worry About
The motor connects directly to the airend through a German-brand maintenance-free coupling. There's no belt, no tensioner, no slippage. Transmission efficiency is 100%, and you never have to schedule belt replacement or deal with the downtime that comes with it. It's one less thing on your maintenance list.
Built to Military Supplier Standards
In 2018, Jinjing Gas was added to the PLA Equipment Supplier Directory with Class B qualification. The company also holds ISO-9001 certification. This two-stage series has earned China's Grade 1 Energy Efficiency Certification and was included in the National Recommended Catalog of Energy-Saving and Carbon-Reducing Technology and Equipment (2025 Edition). Those aren't marketing badges, they're the result of independent testing and factory audits.
Manufacturing and Quality Control
The Jinjing factory covers 15,000 square meters with four modern production lines. The technical team includes 86 senior technicians and engineers. Every new model goes through a 20,000-hour continuous running test that simulates high temperature, high pressure, and frequent start-stop conditions before it's approved for mass production. That's why our units achieve a fault-free operation time of 15,000 hours or more, with a failure rate about 40% lower than the industry average. When you buy a 75kW two-stage screw air compressor from us, it has already been pushed harder than it will ever be pushed in your plant.

FAQ
1. What does "PM VSD" mean on this air compressor?
PM stands for permanent magnet, and VSD stands for variable speed drive. The motor uses rare-earth permanent magnets instead of traditional electromagnetic coils, and the variable frequency drive adjusts motor speed based on real-time air demand. Together they reduce energy consumption by over 32% compared with fixed-speed compressors.
2. What is the advantage of two-stage compression over single-stage?
Two-stage compression splits the compression process into two steps with interstage cooling. This lowers the compression ratio and operating temperature at each stage, which improves efficiency, reduces wear on the airend, and extends oil and bearing life. It is especially beneficial for continuous industrial use.
3. What are the actual specifications of this unit?
100HP / 75kW motor power, 830 CFM (23.5 m³/min) air delivery, 116 PSI (0.3 MPa) working pressure, 2970 r/min speed, 2000 kg weight, and dimensions of 2580 × 1950 × 1990 mm.
4. Is the 116 PSI / 0.3 MPa pressure suitable for my application?
This pressure is ideal for low-pressure, high-flow applications such as textiles, glass manufacturing, certain pneumatic conveying systems, and specific chemical processes. If your equipment requires 7-10 bar, please contact us to confirm availability of a higher-pressure version.
5. What is the energy-saving potential in real operation?
