Hanbell AA-420 Rotary Screw Air End – High-Efficiency Compressor Element for Industrial Applications
The Hanbell AA-420 is a premium-grade rotary screw air end (compressor stage) designed for continuous-duty
industrial air compressors. The AA-420 series is engineered to deliver exceptional reliability, energy efficiency,
and long service life.
| Model | Power (kW) | Rotating speed (rpm) | Air Delivery (m3/min) | Shaft power (kW) | Specific power (kW/m3/min) | S.F. | Dimension(mm) | Weight(kg) |
| AA-420 | 37 | 2950 | 6.2 | 38.2 | 6.1 | 1.03 | 689*357*280 | 155 |
Superior Rotor Profile
Utilizes Hanbell's advanced 5:6 asymmetric rotor profile to minimize internal leakage, reduce energy consumption, and maximize airflow output.
Precision Manufacturing
Rotors are precision-ground from high-strength ductile iron and finished with ultra-tight clearances for optimal volumetric efficiency.
Robust Bearing System
Equipped with heavy-duty cylindrical and angular contact ball bearings (SKF/FAG/NSK) to ensure stable operation under varying loads and high-pressure conditions.
High Mechanical Efficiency
Designed for low rotational resistance, helping to reduce motor power consumption and overall operational costs.
Durable Construction
The housing is made of high-quality nodular cast iron (GGG40), ensuring structural integrity and resistance to thermal deformation.
Versatile Application: Suitable for a wide range of compressor types, including belt-driven and gear-driven systems, with customizable flange and shaft extensions.
Energy Savings
Optimized rotor geometry reduces specific power (kW/m³/min), helping you achieve lower energy bills and a faster ROI.
Proven Reliability
Hanbell air ends are trusted by top compressor manufacturers worldwide for their durability and consistent performance in harsh environments.
Easy Integration
Standardized dimensions and connection interfaces make the AA-420 a direct replacement for many existing compressor units.
Quiet Operation
Precision balancing ensures low vibration and noise levels, improving the working environment.
