Introducing the pinnacle of industrial innovation: Sanzhi (Henan) Compressor Co., Ltd.'s premier Efficient High Capacity Screw Air Compressor for Industrial Use with Versatile Voltage. This meticulously engineered marvel is designed to transform powder conveying applications with superior efficiency and reliability. As a closed-type, low-pressure, stationary screw air compressor, it is the ultimate solution for a variety of demanding sectors, including cement mixing plants, flour mills, coal ash handling, and mineral powder processing. Our state-of-the-art compressor is available in multiple power configurations-11KW, 22KW, 37KW, 45KW, and 55KW-ensuring seamless and robust performance tailored to meet and surpass your industrial requirements.
Why Choose Sanzhi Dust Special Compressor?
The primary function of the specialized low-pressure air compressor designed for dust conveying is to efficiently transport dust, cement, and similar materials. Operating within a pressure range of 0.15-0.4Mpa, this advanced machine utilizes a direct drive system, featuring a large head and low rotational speed. Engineered with a unique oil-air separation structure inspired by German technology, it ensures low noise and minimal vibration, eliminating the need for any foundational installation. The compressor's rapid airflow ensures that the compressed air has an oil content of less than 2PPM, guaranteeing the required air volume. The radiator operates without an after-cooling device, as moisture must be avoided during the conveying process to prevent caking and coking, which can severely impact performance. This meticulous design supports optimum conveying efficacy, whether for cement or even flour.
Sanzhi offers a specialized low-pressure air compressor tailored for dust conveying with diverse applications, including cement, mineral powder, coal ash unloading, and textile fermentation. This high-efficiency, energy-saving solution significantly boosts productivity and cost savings. For instance, unloading a 9.6-meter cement tanker using its built-in device typically takes at least 1.5 hours and is fuel-intensive and inefficient. In contrast, employing a 37KW air compressor from Sanzhi reduces this time to just 40 minutes, drastically enhancing efficiency, conserving energy, and reducing operational costs.

Safe and Zero Leakage Connection
Sanzhi pioneers a departure from conventional hydraulic hose designs. Utilizing high-rigid pipes and flexible joints, the system avoids burst incidents caused by aging. The rubber-type O-ring provides a flexible yet secure seal, ensuring zero leakage.
Aluminum Intake Valve
Engineered to load with electrical power and unload upon power loss, this valve includes air replenishing and noise elimination features. It delivers reliable and consistent performance with a smooth, wear-resistant surface.
Oil Viewing Mirror
Constructed from premium materials, this mirror offers superior transparency, high-temperature resilience, and minimal color shift. It allows visual monitoring of oil levels and lubricating oil usage for timely maintenance, preventing equipment damage.
Excellent Air Filter
Possessing exceptional air purification capabilities, this air filter ensures pristine air through three-stage filtration. It maximizes air purity, meets emission standards, and effectively removes steam and dust.
Oil Filter
This oil filter proficiently eliminates impurities from the lubricating oil, enhancing lubrication for the compressor head and prolonging the lifespan of the air compressor.
High-Quality Soundproof Cotton
Integrating a compact noise reduction housing with premium soundproof cotton, this setup achieves zero vibration amplitude during operation, significantly boosting noise reduction effectiveness.
