The Rotorcomp EVO-6 represents a sixth-generation, advanced asymmetric screw air-end (compressor block) designed for maximum efficiency, durability, and performance in demanding industrial compressed air systems. It serves as the core mechanical component within many premium stationary screw air compressors.
Technical Parameters
| Model | Motor Power(min~max) | Max Flow rate | Pressure Range | Weight | |||
| kW | HP | m3/min | cfm | bar | psi | kg | |
| EVO6 | 15~37 | 20~50 | 6.2 | 220 | 5~15 | 70~220 | 45 |
Asymmetric 5+6 Rotor Profile: The core innovation is its patented rotor profile featuring 5 lobes on the male rotor and 6 flutes on the female rotor. This optimized geometry creates a larger compression volume and a more gradual, internal compression process.
Large Bearing Span & Sturdy Design: Engineered with an exceptionally large distance between the main bearings, providing superior rotor stability, reducing shaft deflection, and minimizing wear under high load conditions.
Optimized Oil Injection System: Features precision-designed oil injection ports and flow paths that ensure optimal thermal management (cooling), efficient sealing, and lubrication with minimal pressure drop.
High-Grade Materials: Manufactured from high-strength, wear-resistant cast iron or specialized alloys, with rotors often coated for reduced friction and enhanced corrosion resistance.
Integrated Efficiency Design: Every aspect, from the rotor helix angle to the discharge port size and shape, is engineered to maximize adiabatic efficiency across a wide operating range.
Superior Energy Efficiency: The asymmetric 5/6 profile achieves higher volumetric and adiabatic efficiency than traditional symmetric profiles (e.g., 4+6). This translates directly into lower specific power consumption (kW/cfm) and significant reductions in electricity costs, offering a fast return on investment (ROI).
Exceptional Reliability & Long Life: The robust construction, large bearing span, and optimal thermal management drastically reduce mechanical stress and wear. This results in extended service intervals, lower maintenance costs, and a dramatically longer operational lifespan (often exceeding 100,000 hours) before a potential overhaul is needed.
High Flow Output: The efficient profile allows for a greater air displacement per rotor volume, enabling a compact air-end to deliver a higher actual cubic feet per minute (ACFM) output compared to many similarly sized units.
Stable Pressure & Consistent Performance: The precise engineering ensures minimal internal leakage and stable compression, leading to consistent air output and pressure, which is critical for sensitive industrial processes.
Reduced Noise & Vibration: The smooth, gradual meshing of the rotors and stable operation contribute to lower noise and vibration levels, enhancing the working environment.
Manufacturing & Automation: CNC machining centers, pneumatic assembly lines, packaging machinery, and robotics.
Process Industries: Chemical, pharmaceutical, and food & beverage plants (when paired with appropriate air treatment).
Textile Industry: Powering spinning, weaving, and dyeing processes.
Plastics & Rubber: Injection molding, blow molding (like PET bottle production), and extrusion.
Mining & Construction: Providing reliable power for tools and controls in stationary equipment.
As a Premium Component: It is widely used by leading compressor manufacturers as the core of their high-efficiency, variable speed drive (VSD) and fixed-speed compressor models.
