The Hanbell AC-780R is a flagship, large-capacity two-stage rotary screw air compressor engineered for ultimate energy efficiency, unparalleled reliability, and continuous heavy-duty operation in the most demanding industrial environments. It represents the peak of Hanbell's technology, designed for users where compressed air is a critical and costly utility.
Technical Parameters
| Model | Power (kW) | Rotating speed (rpm) | Air Delivety (m3/min) | Shaft power (kW) | Specific power (kW/m3/min) | Dimension(mm) | Weight(kg) |
| AC-780R | 75 | 3000 | 12.6 | 74.7 | 5.93 | 650*380*350 | 195 |
Advanced Two-Stage Compression Air End: The core of the "R" series. It features two distinct pairs of rotors that compress air in sequential stages. This design dramatically reduces energy consumption, lowers operational temperatures and mechanical stress on each stage, and achieves a superior volumetric efficiency compared to any single-stage compressor.
Ultra-High Efficiency Permanent Magnet Synchronous Motor (PMSM): Powered by a premium, low-speed PMSM motor. This motor provides a near-perfect power factor, exceptional performance across its entire operational range, and superior energy efficiency, especially under partial load conditions—which is where compressors spend most of their time.
Sophisticated Intelligent Control System: Equipped with a state-of-the-art touchscreen controller (likely with IoT capabilities). It offers full-system monitoring, advanced diagnostics, customizable operating modes, and remote connectivity for real-time data analysis and predictive maintenance, enabling smart factory integration.
Optimized Vertical Cooling System (Likely Configuration): For a model this size, Hanbell often employs a vertical design with a forced-draft cooling system. This ensures maximum heat dissipation efficiency in a compact footprint, maintaining ideal operating temperatures even in high-ambient conditions and contributing to long-term reliability.
Robust, Industrial-Grade Construction: Built to industrial standards with a heavy-gauge steel frame and a full-access, acoustically insulated canopy. This design ensures exceptional durability, minimizes structural vibrations, significantly reduces noise levels, and allows for easy maintenance access.
System-Engineered for Minimal Pressure Drop: Every component, from the oversized intake filter and minimal-bend piping to the high-capacity oil separator, is designed to reduce air flow resistance. This holistic engineering approach eliminates inefficiencies and contributes directly to lower energy consumption.
Maximum Energy Savings & Lowest Operating Cost: The synergy between the two-stage compression and the PMSM motor results in exceptional energy efficiency, often exceeding that of single-stage and even older two-stage models. This makes the AC-780R the optimal choice for minimizing electricity costs, which constitute the largest portion of a compressor's total cost of ownership (TCO).
Unrivaled Reliability for Critical Operations: The two-stage design inherently reduces the load and thermal stress on each compression stage, leading to less wear and a significantly longer lifespan for core components. This engineering philosophy ensures maximum uptime for processes where air supply is indispensable.
Exceptional Performance Stability: Provides extremely stable discharge pressure and air flow, even with significant demand fluctuations. This ensures consistent air quality and pressure for sensitive manufacturing tools and processes.
Lowest Lifecycle Cost (TCO): While the initial investment is substantial, the AC-780R is designed for the lowest TCO. This is achieved through drastically reduced energy consumption, extended service intervals, superior reliability that minimizes downtime, and long component life.
Smart and Connected: The advanced control system transforms the compressor from a standalone machine into a connected asset. It provides valuable data for optimizing entire compressed air systems, scheduling maintenance before issues arise, and managing energy usage effectively.
Heavy Industrial Manufacturing: Such as automotive manufacturing plants (e.g., paint shops, assembly lines), large steel mills, and metal fabrication facilities.
Mining & Mineral Processing: Providing air for large pneumatic networks, grinding mills, flotation cells, and drilling operations in remote and demanding locations.
Oil & Gas and Petrochemical Refineries: For process air, instrument air, and plant air in critical refining and processing applications where reliability is non-negotiable.
Power Generation Plants: Serving as the primary air source for soot blowing, fluidizing, and control systems in thermal power stations.
Large Cement & Glass Plants: Powering extensive production processes, control systems, and automation lines.
Massive Scale Workshops & Shipyards: Where a central, highly reliable source of high-volume compressed air is required to power numerous tools and systems simultaneously.
