Industrial Two Stage Rotary Air Compressor 12.5 Bar Permanent Magnet VSD Screw Compressor
CE Two Stage Rotary Air Compressor
,Two Stage Rotary Air Compressor 12.5 Bar
,Permanent Magnet VSD Screw Compressor
In modern manufacturing, where high precision is paramount, compressed air is hailed as the "fourth largest utility resource," and its stability directly impacts the operational quality of the entire production line. This RAT45/12.5VSD two-stage screw air compressor is specifically designed to address factory downtime risks and pressure fluctuations. Through two-stage compression technology, the equipment provides more abundant airflow while significantly reducing the load and wear on single-stage rotors, ensuring an extended lifespan under heavy-duty conditions. Combined with an intelligent PLC operating system, it provides a constant air supply pressure to the production line, effectively preventing increased scrap rates due to unstable air pressure. It is an indispensable power source for automated assembly, precision machining, and large-scale manufacturing centers. Reshaping the cost structure: from energy burden to sustainable profit growth. For any manufacturing company, the electricity cost of air compressors typically accounts for over 70% of its total lifecycle cost.
Our solution, through the deep integration of an ultra-high-efficiency permanent magnet motor and VSD variable frequency control, completely solves the problem of energy waste during low peak air consumption periods in factories. Two-stage compression technology achieves near-isothermal compression through interstage cooling, improving physical energy efficiency by up to 15%. This means that your factory can not only recover the equipment purchase cost through electricity savings within 12-18 months, but also transform high energy consumption expenses into tangible profit surpluses over a ten-year service life, helping your company maintain a low-cost operating advantage in fierce market competition.

Dual-Stage Compression
Lower Loads, Longer Life. This dual-stage compressor employs a two-stage tandem rotary screw structure, distributing the total pressure ratio across two independent compression stages. This structure significantly reduces the pressure ratio in each compression stage. The reduced pressure ratio per stage means a substantial decrease in radial forces on the bearings and rotor. Compared to single-stage compressors, this results in less mechanical wear, a lower failure rate, and a significantly extended overhaul cycle, ensuring reliable 24/7 plant operation.
Near-Isothermal Efficiency
Higher Air Delivery, Lower Cost. A highly efficient oil-injection cooling/interstage cooling system is designed between the first and second stages of compression. Interstage cooling lowers the air temperature entering the second stage, bringing the compression process closer to the energy-efficient "isothermal compression" process. This optimization of the physical structure allows the unit to save more than 15% energy compared to single-stage models at the same power output, providing greater actual air production for manufacturing industries and directly reducing the electricity cost per cubic meter of compressed air.
Integrated PM VSD Drive
Smart Matching, Constant Pressure (Permanent Magnet Variable Frequency Drive Integration: Precise Matching, Constant Pressure Output) Structural Features:Employs an IE5 ultra-high-efficiency oil-cooled permanent magnet motor combined with the Inovance variable frequency control system. Unlike traditional fixed-frequency machines that frequently start, stop, or unload, the permanent magnet variable frequency structure allows the system to smoothly adjust the motor speed within a specified range based on real-time changes in the factory's gas consumption. This "on-demand gas supply" mode not only eliminates energy waste during unloading but also ensures pressure fluctuations are maintained on the downstream production line, effectively improving the yield rate of precision-manufactured products.
