Product Structure

Why choose Sanzhi dust special compressor?

Introducing the groundbreaking low-pressure air compressor by Sanzhi, a marvel meticulously crafted for the nuanced demands of dust conveying. This essential powerhouse is engineered for seamless transport of dust, cement, and various materials with unmatched efficiency. Operating effortlessly within a pressure range of 0.15-0.4Mpa, this state-of-the-art machine features a direct drive mechanism, a generously sized head, and a low-speed rotation to optimize performance. Highlighting an extraordinary oil-air separation structure, it is expertly crafted with the precise German engineering standards. Benefit from exceptionally low noise levels and minimal vibration, ensuring a quiet and smooth operation that meets the highest standards of performance. Its foundation-free installation simplifies setup, offering remarkable ease. Impressively, the compressor provides a swift flow of compressed air with an oil content below 2PPM, perfectly fulfilling volume demands. The radiator's innovative design eliminates the need for an after-cooling device, making it the ideal choice for moisture-sensitive materials like cement and flour. This prevents coking and caking, guaranteeing smooth and uninterrupted conveyance.

Sanzhi proudly unveils a specialized low-pressure air compressor, expertly tailored for dust conveying with diverse applications spread across sectors such as cement, mineral powder, coal ash unloading, and textile fermentation. This avant-garde compressor is the epitome of efficiency and energy conservation.
