Why Choose Sanzhi Dust Special Compressor?
The main function of the Sanzhi special low-pressure air compressor for dust conveying is to efficiently transport dust, cement, and similar materials. Operating at a working pressure range of 0.15-0.4Mpa, this compressor features a direct drive system, a large head, a low rotational speed, and a unique oil-air separation structure designed with advanced German technology. This combination ensures low noise and minimal vibration, eliminating the necessity for any foundational installation. The rapid flow rate of the compressed air, with an oil content of less than 2PPM, guarantees that the air volume meets all requirements. Our radiator is engineered without an after-cooling device to prevent moisture during transportation, thereby avoiding the coking and caking that could severely impact the conveying process.
Sanzhi's special low-pressure air compressor for dust conveying boasts a broad array of applications, making it ideal for cement, mineral powder, coal ash unloading, textile fermentation, and more. Its high efficiency and energy-saving capabilities are unmatched. Consider the stark difference in performance: a 9.6-meter cement tanker's built-in unloading device takes at least one and a half hours, consumes excessive fuel, and is highly inefficient. In contrast, our 37KW air compressor completes the same task in just 40 minutes, significantly boosting efficiency while saving both energy and costs.
Direct-Connected Rotation Motor
With an insulation grade of F and a protective grade of IP55, our motor ensures a stable flow rate, offering constant load performance, unparalleled efficiency, and remarkable durability.
German Technology Air End
Our air end features a large rotor and low-speed design, ensuring high efficiency with minimal noise and vibration. It boasts exceptional reliability, reduced leakage, and superior volume efficiency.
Smart Button Screen
Experience simplicity and clarity with our Smart Button Screen. Easy to operate, it offers a fast response time, vivid display colors, and straightforward maintenance.
Cooling System
Our cutting-edge cooling system, designed with a large heat exchange area, effectively prevents high temperatures. It reduces oil emulsification and coking, ensuring your machine runs smoothly.
Reliable Oil and Air Separator
Featuring a vertical tangential cyclone separation structure, our separator ensures complete separation of oil and air. It simplifies cartridge replacement and reduces maintenance costs.
Safe and Zero Leakage Connection
Sanzhi eschews traditional hydraulic hose designs in favor of high-rigid pipes and flexible joint connections. This modern approach prevents bursts and ensures a leak-free operation with a rubber type O-ring seal.
Aluminum Intake Valve
Our aluminum intake valve operates efficiently, powered by electricity for loading and unloading. It features air replenishing and noise-reducing functions, ensuring stable, durable, and wear-resistant performance.
Oil Viewing Mirror
Crafted from *** material, our oil viewing mirror offers excellent transparency and high-temperature resistance. It allows you to monitor oil levels and lubrication status easily, ensuring timely replacements to avoid equipment damage.
Excellent Air Filter
Our top-tier air filter guarantees a pristine air system with three-stage filtration, removing steam and dust gases. It maximizes air purification, meeting standard emission requirements.
Oil Filter
Designed to filter impurities from the lubricating oil, our oil filter enhances lubrication and extends the lifespan of your air compressor.
High-Quality Soundproof Cotton
Encased in a compact noise reduction housing, our premium soundproof cotton eliminates vibration during operation, significantly enhancing noise reduction.
