The Panrui PRSF vertical two-stage PM VSD screw air compressor delivers high-volume, energy-efficient compressed air for heavy-duty industrial applications. Its vertical two-stage layout provides a compact footprint with large flow capacity.
Key Features
- Vertical two-stage compression for high flow and excellent energy efficiency.
- Permanent magnet synchronous motor with VSD control for precise, efficient air delivery.
- Direct-drive coaxial design for low vibration and long service life.
- Hard-pipe circuit and multi-layer seals for leak-free operation.
- Enhanced cooling system for stable running under high-temperature conditions.
- Three-stage oil separation for clean, low-oil-content air.
