Product Structure

Why choose Sanzhi dust special compressor?

Introducing the groundbreaking low-pressure air compressor from Sanzhi, expertly crafted to redefine dust conveying. This essential powerhouse is designed for the efficient transportation of dust, cement, and a multitude of materials with unmatched precision. Operating within a pressure range of 0.15-0.4Mpa, it features a direct drive mechanism, an expansive head, and a low rotational speed to ensure optimal performance. The distinctive oil-air separation structure, inspired by precision German engineering, guarantees exceptionally low noise and minimal vibration. The compressor's foundation-free installation makes it remarkably easy to set up. Delivering a rapid flow of compressed air with an oil content of less than 2PPM, it flawlessly meets volume requirements. With a radiator designed to eliminate the need for an after-cooling device, it is perfectly suited for moisture-sensitive materials like cement and flour, preventing coking and caking, and ensuring smooth and continuous conveyance.

Sanzhi proudly unveils a specialized low-pressure air compressor, masterfully crafted for dust conveying and celebrated for its versatility in sectors like cement, mineral powder, coal ash unloading, and textile fermentation. This innovative compressor embodies the pinnacle of efficiency and energy-saving technology. Consider the case of a standard 9.6-meter cement tanker, typically requiring over an hour and a half to unload with its equipment, leading to high fuel consumption and inefficiency. Sanzhi's powerful 37KW air compressor revolutionizes this process, reducing unloading time to a swift 40 minutes, dramatically boosting efficiency, significantly cutting fuel consumption, and offering considerable cost savings.
