Product Structure

Why choose Sanzhi dust special compressor?

Discover the cutting-edge advances in our special low-pressure air compressor, meticulously engineered for unparalleled dust conveying capabilities. This indispensable tool excels in efficiently transporting materials like dust, cement, and more. With an impressive operating pressure range of 0.15-0.4Mpa, it boasts a direct drive, an extensively sized head, and an optimized low rotational speed to ensure superior performance. The distinctive oil-air separation structure, crafted with precision German engineering, guarantees minimal noise and vibration, enhancing the user experience. Installation is hassle-free, requiring no foundational support. This compressor ensures rapid compressed air flow with oil content under 2PPM, meeting all volume needs effortlessly. Its radiator, designed without an after-cooling device, is ideal for moisture-sensitive materials like cement and flour, effectively preventing coking and caking, thus ensuring flawless conveyance.

Sanzhi proudly presents its specialized low-pressure air compressor, a revolutionary solution dedicated to dust conveying with remarkable versatility across sectors such as cement, mineral powder, coal ash unloading, and textile fermentation. Celebrated for its efficiency and energy-saving prowess, this innovative compressor sets a new standard. For example, a 9.6-meter cement tanker ordinarily requires over an hour and a half for unloading with standard equipment, leading to excessive fuel use and inefficiency. In contrast, Sanzhi's commanding 37KW air compressor slashes unloading time to just 40 minutes, dramatically boosting efficiency, curtailing fuel consumption, and providing substantial cost savings.
