Product Structure

Why choose Sanzhi dust special compressor?

Embark on a journey into the future of dust conveying technology with our extraordinary Industrial Low-Pressure Screw Air Compressor. This elegant creation is a testament to precise engineering and cutting-edge functionality. Expertly crafted to tackle the complexities of transporting materials like dust and cement with utmost efficiency, this powerhouse operates seamlessly within a dynamic pressure range of 0.15-0.4Mpa. Its direct drive benefits from a generously dimensioned head and an optimized low rotational speed, ensuring unrivaled performance. The compressor boasts an exceptional oil-air separation structure, with German-engineered precision facilitating a tranquil operational environment characterized by minimal noise and vibration. Revel in the ease of installation, as no foundational support is necessary. Experience the rapid flow of compressed air with an impressively low oil content of less than 2PPM, precisely tailored to your volume needs. Additionally, the radiator's design eliminates the need for after-cooling devices, making it ideal for transporting moisture-sensitive materials such as cement and flour. This innovative design prevents issues like coking and caking, ensuring flawless material conveyance.

Sanzhi is proud to introduce its groundbreaking low-pressure air compressor, a brilliant innovation designed for superior dust conveying efficiency across a wide spectrum of industries. Whether handling cement, mineral powder, coal ash unloading, or textile fermentation, this compressor offers unparalleled versatility and energy efficiency. Setting a new benchmark in operational excellence, it revolutionizes processes. Picture a 9.6-meter cement tanker, which traditionally requires over 90 minutes for unloading with conventional equipment, leading to excessive fuel costs and inefficiencies.
