The Rotorcomp EVO-2 is a second-generation screw compressor element that established a significant performance leap over its predecessors. While superseded by newer generations like the EVO-6, the EVO-2 remains a benchmark for robust, efficient, and reliable compression technology, representing the foundational shift towards modern asymmetric rotor profiles.
Technical Parameters
| Model | Motor Power(min~max) | Max Flow rate | Pressure Range | Weight | |||
| kW | HP | m3/min | cfm | bar | psi | kg | |
| EVO2 | 2.2~11 | 3~15 | 1.6 | 56 | 5~15 | 70~220 | 16 |
Advanced Asymmetric Rotor Profile: The EVO-2's core innovation was its high-performance asymmetric rotor profile. This design, an evolution from basic symmetric profiles, optimizes the sealing line between the male and female rotors, creating a more efficient internal compression process.
Optimized Rotor Geometry: The profile is engineered to reduce internal leakage (blowhole) and minimize airflow resistance during the meshing cycle, directly improving volumetric efficiency.
Robust Construction: Built with high-strength cast iron housing and precision-machined rotors, it is designed for continuous industrial duty. The construction emphasizes long-term stability and resistance to thermal and mechanical stress.
Integrated Bearing & Sealing System: Designed with a reliable bearing layout and effective shaft seals to maintain internal pressures and oil integrity, contributing to sustained performance over time.
Proven Design Platform: The EVO-2 served as the reliable workhorse platform for many mid-range to high-end stationary air compressors before the advent of the EVO-3/EVO-6 series.
Significant Efficiency Gain: Compared to first-generation symmetric rotors, the EVO-2 delivered a substantial improvement in adiabatic and volumetric efficiency, leading to meaningful reductions in specific energy consumption (kW/cfm) and operational costs.
Enhanced Reliability & Durability: Its robust design and superior materials translated into a long operational lifespan, excellent tolerance for demanding duty cycles, and reduced risk of premature failure. It established a high standard for mean time between failures (MTBF).
Stable Air Delivery: The optimized profile provided more consistent compression with less pulsation, resulting in stable discharge pressure and air flow—a critical factor for sensitive pneumatic tools and processes.
Lower Operating Temperatures: Improved internal aerodynamics and sealing contributed to more efficient heat management during compression, often leading to lower operating oil and discharge air temperatures, which extends the life of oil and filters.
Strong Cost-to-Performance Value: While newer generations push the efficiency boundary further, the EVO-2 continues to offer an exceptional balance of performance, reliability, and total cost of ownership, especially in refurbished or well-maintained units.
General Manufacturing & Workshops: Machine shops, automotive repair, metal fabrication, and assembly lines powering pneumatic tools, clamps, and cylinders.
Packaging Industry: Operating fillers, cappers, labelers, and packaging machinery.
Plastics Processing: Providing plant air for auxiliary equipment in injection molding, blow molding (for general cooling/actuation), and extrusion lines.
Textile Industry: Powering air jets in looms and other processing machinery.
Construction & Material Handling: Used in stationary compressors supporting sandblasting, painting, and material conveyance systems.
Agriculture & Food Processing (with proper air treatment): For grain handling, packaging, and general plant automation.
