Product Structure

Why choose Sanzhi dust special compressor?

Unlock the future with our low-pressure air compressor, expertly designed to revolutionize dust conveying. Engineered with precision, this dynamic tool is perfect for transporting dust, cement, and a variety of materials. Operating flawlessly within a pressure range of 0.15-0.4Mpa, it features a sleek direct drive, expansive head, and finely-tuned low rotational speed to deliver exceptional performance. The compressor's German-engineered oil-air separation structure ensures minimal noise and vibration, enhancing user satisfaction. Installation is a breeze, requiring no foundation. Experience swift air flow with oil content under 2PPM, effortlessly meeting all volume demands. Its radiator, crafted without an after-cooler, excels with moisture-sensitive materials like cement and flour, preventing coking and caking for seamless conveyance.

Sanzhi introduces its game-changing low-pressure air compressor, tailored for dust conveying, and versatile across industries such as cement, mineral powder, coal ash unloading, and textile fermentation. Lauded for its exceptional efficiency and energy-saving capabilities, this state-of-the-art compressor redefines standards.
