Why Choose the Sanzhi Dust Special Compressor?
Our Special Low Pressure Air Compressor for Dust Conveying is meticulously engineered to tackle dust, cement, and other particulates with unparalleled efficiency. Operating within a pressure range of 0.15-0.4Mpa, this masterpiece features a direct drive mechanism, a robust large head, and a low rotational speed for superior performance. Leveraging advanced German technology, it boasts a unique oil-air separation structure to ensure minimal noise and vibration. No foundation is required for installation, making setup a breeze. The compressed air, with an oil content of less than 2PPM, flows swiftly to guarantee optimal air volume. Additionally, the radiator is ingeniously designed without an after-cooling device to prevent moisture accumulation in materials such as cement and flour, thus avoiding coking and caking for smooth and seamless conveying.
Sanzhi's special low-pressure air compressor for dust conveying exemplifies versatility and high efficiency, serving a wide array of applications including cement, mineral powder, coal ash unloading, and textile fermentation. This powerhouse not only saves energy but also significantly enhances productivity. For instance, unloading a 9.6-meter cement tanker using traditional equipment takes over 1.5 hours and guzzles a considerable amount of fuel. In stark contrast, our 37KW air compressor accomplishes the same task in just 40 minutes, delivering remarkable efficiency and substantial cost savings.
Direct-Connected Rotation Motor
Featuring an insulation grade of F and a protective grade of IP55, this motor guarantees a steady flow rate, consistent load handling, outstanding efficiency, and exceptional longevity.
German Technology Air End
Our air end, designed with a large rotor and low-speed mechanism, promises high efficiency, low noise, minimal vibration, and superior reliability. It features reduced leakage and enhanced volume efficiency.
Smart Button Screen
The intuitive smart button screen offers clear and concise functions, straightforward operation, rapid response times, and vibrant display colors, making maintenance effortless.
Cooling System
With a large heat exchange area, our cooling system efficiently prevents high temperatures, minimizing oil emulsification and coking, thus maintaining optimal machine performance.
Reliable Oil and Air Separator
Our innovative vertical tangential cyclone separation system ensures complete oil and air separation, facilitating easy cartridge replacement and reducing maintenance costs.
Safe and Zero Leakage Connection
Moving beyond traditional low-cost hydraulic hoses, Sanzhi employs high-rigidity pipes and flexible joint connections. This design prevents bursts and ensures a flexible seal with rubber-type O-rings, guaranteeing zero leakage.
Aluminum Intake Valve
Our electrically-operated aluminum intake valve features unloading and air replenishment capabilities while minimizing noise. It promises stable, durable performance with a smooth, wear-resistant surface.
Oil Viewing Mirror
Crafted from high-quality PMMA material, our oil viewing mirror offers exceptional transparency, high-temperature resistance, and minimal color change. It allows for visual monitoring of oil levels and lubrication, ensuring timely replacements to prevent equipment damage.
Excellent Air Filter
Our superior air filter ensures exceptional air purification through a three-stage filtration process. It effectively removes steam and small dust particles, meeting standard emissions and maintaining optimal air quality.
