Product details

The 20HP Industrial Frequency Screw Air Compressor is engineered for factories that demand continuous, stable airflow supported by a highly reliable fixed-speed design. At its core is an advanced microcomputer control system built with a simplified-Chinese LCD interface and a responsive touch panel developed for domestic industrial habits. Operators only need to press the start and stop keys—no professional training is required, making integration fast for workshops upgrading from smaller 20 hp compressor units. The intelligent controller conducts real-time supervision of parameters such as load, temperature, and rotation state, and immediately triggers shutdown when overload, reverse-phase, extended idle running, or excessive temperature conditions arise. This fully automated protection structure provides the foundation for 24-hour unattended operation in production environments.

Once activated, the motor maintains a stable rated speed regardless of whether air consumption rises or falls, demonstrating the characteristic constant-frequency behavior emphasized in the Chinese description. The compressor manages loading and unloading through a precision pressure-switch mechanism: when pressure inside the tank reaches the upper threshold, the machine unloads and stops; once pressure drops to the lower limit, it immediately reloads and resumes output. This form of capacity modulation—often referred to as “reservoir-based control”—is ideal for facilities with a smooth consumption curve. Industries such as woodworking, textile finishing, electronics assembly, and small-to-medium CNC workshops benefit significantly from this stability. For applications where the demand curve fluctuates dramatically, users may complement this model with a PM VSD Screw Air Compressor, creating a hybrid layout that optimizes energy performance across all operating conditions.

Built for long operating cycles, the SA-20A model is designed to perform reliably within ambient temperatures ranging from –5°C to +45°C. It uses an efficient air-cooling configuration combined with an 18-liter lubrication system that protects the screw element during high-load operation. Noise levels remain controlled at approximately 66±2 dB, ensuring a quieter workshop environment compared with many older Screw air compressor units. The compact structure—1080 mm in length, 750 mm in width, 1030 mm in height—allows placement in limited factory spaces without major workflow disruption. At 380 kg, the machine maintains the rigidity required to minimize vibration and enhance long-term component stability. The 3/4'' discharge port provides compatibility with standard pipelines and simplifies integration into existing air networks.

Selecting between an industrial-frequency compressor and a variable-speed model always begins with analyzing your air-use pattern. If the consumption curve remains linear and predictable, a fixed-speed system like the 20HP Industrial Frequency Screw Air Compressor offers the most economical solution. With its constant-speed motor, automated protection logic, simplified control interface, pressure-switch-based capacity regulation, and dependable mechanical structure, this 20 hp screw compressor supports a wide range of industrial scenarios—from assembly lines and pneumatic production tools to packaging machinery, painting booths, and fabrication shops. Whether used as a standalone core unit or positioned as the base-load machine in a multi-compressor layout, it ensures stable output, reduced maintenance effort, and long-term cost efficiency, making it a practical choice for factories seeking dependable compressed-air performance.
