Why choose Sanzhi dust special compressor?
The core functionality of our specialized low-pressure air compressor designed for dust conveying is impressive. Engineered to transport dust, cement, and other fine particles, this unit operates with a working pressure range of 0.15-0.4Mpa. It features a direct drive, large head, and low rotational speed, coupled with a cutting-edge oil-air separation structure crafted with German technology. This results in minimal noise and vibration, eliminating the need for any installation foundation. The high-speed airflow ensures the compressed air's oil content remains below 2PPM, meeting stringent air volume requirements. Notably, our radiator is built without an after-cooling device to prevent moisture during transport, ensuring materials like cement and flour do not suffer from coking or caking-guaranteeing superior conveying performance.
Sanzhi's specialized low-pressure air compressor for dust conveying stands out with its broad applicability, covering industries such as cement, mineral powder, coal ash unloading, and textile fermentation. This compressor is designed for maximum efficiency and energy conservation. For instance, a standard 9.6-meter cement tanker typically takes at least one and a half hours to unload using its built-in device, consuming excessive fuel and time. In contrast, with our 37KW air compressor, the unloading time is drastically reduced to just 40 minutes, significantly boosting efficiency and reducing both energy consumption and operational costs.
Direct-Connected Rotation Motor
Boasting insulation grade F and protective grade IP55, this motor ensures a stable flow rate. It delivers constant load performance with exceptional efficiency and durability.
German Technology Air End
Our air end features a large rotor and a low-speed design, ensuring high efficiency, low noise, minimal vibration, and outstanding reliability. This design minimizes leakage and maximizes volume efficiency.
Smart Button Screen
With intuitive functions, straightforward operation, rapid response times, and clear display colors, our smart button screen is easy to maintain and user-friendly.
Cooling System
Engineered with a large heat exchange area, this cooling system effectively prevents high-temperature malfunctions. It reduces the risk of oil emulsification and coking due to elevated temperatures.
Reliable Oil and Air Separator
Featuring a vertical tangential cyclone separation structure, our separator ensures complete oil and air separation. The cartridge is easy to replace, reducing maintenance costs.
Safe and Zero Leakage Connection
Sanzhi replaces traditional low-cost hydraulic hoses with high-rigid pipes and flexible joint connections. This innovation prevents bursts common with aging hoses and uses rubber O-rings for flexible, leak-proof seals.
Aluminum Intake Valve
This valve operates with a principle of electrical loading and unloading. It functions to unload and replenish air, reduce host noise, and offers stable, durable performance with a smooth, wear-resistant surface.
Oil Viewing Mirror
Crafted from *** material, this oil viewing mirror provides excellent transparency, high temperature resistance, and minimal color change. It allows for easy monitoring of oil levels and lubrication needs, facilitating timely replacements and additions to avoid equipment damage.
Excellent Air Filter
Our superior air filter ensures a clean air system through three-stage filtration, maximizing air purification and meeting standard emissions. It effectively removes steam and fine dust particles.
Oil Filter
This robust oil filter removes impurities from the lubricating oil, enhancing head lubrication and extending the life of the air compressor.
High-Quality Soundproof Cotton
Our compact noise reduction housing, combined with high-quality soundproof cotton, achieves minimal vibration and significantly improved noise reduction levels during operation.
