Product Structure

Why choose Sanzhi dust special compressor?

Introducing the revolutionary low-pressure air compressor by Sanzhi, meticulously designed for dust conveying-an essential powerhouse for transporting dust, cement, and a variety of materials with unparalleled efficiency. Operating seamlessly within a pressure range of 0.15-0.4Mpa, this machine boasts a direct drive mechanism, a generously sized head, and a low rotational speed for optimal performance. Highlighting a distinctive oil-air separation structure, expertly engineered with precision German craftsmanship, this compressor offers exceptionally low noise levels and minimal vibration. Its foundation-free installation makes setup remarkably straightforward. Impressively, the compressor delivers a swift flow rate of compressed air with an oil content of less than 2PPM, perfectly meeting volume requirements. The radiator's innovative design eliminates the need for an after-cooling device, making it ideal for moisture-sensitive materials like cement and flour, thereby preventing coking and caking, and ensuring smooth and uninterrupted conveyance.

Sanzhi proudly presents a specialized low-pressure air compressor tailored for dust conveying, famed for its diverse applications across sectors such as cement, mineral powder, coal ash unloading, and textile fermentation. This groundbreaking compressor stands as a symbol of efficiency and energy conservation. Take, for example, a typical 9.6-meter cement tanker, which would ordinarily take over an hour and a half to unload using its own equipment, with high fuel consumption and inefficiency. With Sanzhi's powerful 37KW air compressor, unloading time is dramatically reduced to just 40 minutes, significantly enhancing efficiency, slashing fuel consumption, and offering substantial cost savings.
