Panrui PRFF permanent-magnet variable-speed 4-in-1 screw air compressor integrates compressor, air tank, refrigerated dryer and three-stage filtration in one cabinet, reducing floor space by more than 60% and replacing a traditional split air station.
4-in-1 Advantages
- Extreme space saving: single integrated cabinet, no separate piping or civil works.
- Permanent-magnet VSD core saves 25–35% energy versus fixed-speed machines.
- Built-in refrigerated dryer (3–10°C pressure dew point) and three-stage filtration keep oil carry-over ≤0.01 ppm.
- Plug-and-play: pre-installed piping, 2-hour commissioning, just connect 380V and outlet pipe.
- Touch-screen centralized control with optional IoT remote monitoring; noise 66–68 dB.
- Every unit runs a 12–72 hour full-load factory test before delivery.
