Why Choose Sanzhi Dust Special Compressor?

The main function of the Sanzhi special low-pressure air compressor for dust conveying is to efficiently transport dust, cement, and similar materials. Operating at a working pressure range of 0.15-0.4Mpa, this compressor features a direct drive system, a large head, a low rotational speed, and a unique oil-air separation structure designed with advanced German technology. This combination ensures low noise and minimal vibration, eliminating the necessity for any foundational installation. The rapid flow rate of the compressed air, with an oil content of less than 2PPM, guarantees that the air volume meets all requirements. Our radiator is engineered without an after-cooling device to prevent moisture during transportation, thereby avoiding the coking and caking that could severely impact the conveying process.

Sanzhi's special low-pressure air compressor for dust conveying boasts a broad array of applications, making it ideal for cement, mineral powder, coal ash unloading, textile fermentation, and more. Its high efficiency and energy-saving capabilities are unmatched. Consider the stark difference in performance: a 9.6-meter cement tanker's built-in unloading device takes at least one and a half hours, consumes excessive fuel, and is highly inefficient. In contrast, our 37KW air compressor completes the same task in just 40 minutes, significantly boosting efficiency while saving both energy and costs.
