Product Structure

Why choose Sanzhi dust special compressor?

Step into the future of dust conveying technology with our premium low-pressure air compressor, a stunning masterpiece of meticulous engineering and advanced functionality. Meticulously designed to conquer the challenges of efficiently transporting materials like dust and cement, this powerhouse operates within a versatile pressure range of 0.15-0.4Mpa. Its direct drive is enhanced by an extensively proportioned head and optimized low rotational speed, all contributing to its unparalleled performance. The compressor features a distinguished oil-air separation structure, where precision German engineering ensures a serene operational environment with minimal noise and vibration. You'll delight in the seamless installation process, as it requires no foundational support. Experience rapid airflow of compressed air with an exceptionally low oil content of under 2PPM, perfectly tailored to meet your volume requirements. Additionally, the radiator boasts a design free from after-cooling devices, making it superb for transporting moisture-sensitive materials such as cement and flour. This design effectively prevents issues like coking and caking, facilitating impeccable material conveyance.

Sanzhi proudly unveils its trailblazing low-pressure air compressor, an innovative marvel engineered for exceptional dust conveying proficiency across a myriad of industries. Whether dealing with cement, mineral powder, coal ash unloading, or textile fermentation, this compressor showcases unmatched versatility and energy-saving capabilities.
