The Hanbell AB-077 is a low-power (7.5 kW / 11 kW) oil-injected screw air compressor air end. Featuring a belt-driven design, it is a standard-pressure model specifically engineered for 50 Hz power supplies. Its core parameters are as follows: a discharge volume of 1.0–1.5 m³/min, an operating pressure of 8–13 bar, and a rotational speed of 3,420–5,200 rpm.
Technical Parameters
| Model | Power (kW) | Rotating speed (rpm) | Air Delivery (m3/min) | Shaft power (kW) | Specific power (kW/m3/min) | S.F. | Dimension(mm) | Weight(kg) |
| AB-077 (Belt) | 7.5 | 3420 | 1 | 7.3 | 7.4 | 0.97 | 262*180*150 | 25 |
| AB-077 (Belt) | 11 | 5200 | 1.5 | 11 | 7.2 | 1 | 262*180*150 | 25 |
1. High Efficiency and Energy Saving
Features a 5:6 rotor tooth ratio design with an optimized rotor profile to minimize internal backflow losses, achieving a specific power (energy consumption) as low as 7.2–7.4 kW/m³/min.
2. Long-Life Design
Employs a six-bearing support structure to enhance rotor stability, reduce wear, and extend service life.
3. Low Vibration and Noise
High-precision rotor machining ensures smooth operation, resulting in minimal vibration and low noise levels.
4. Excellent Sealing
Strictly controls the clearance between the rotor and the housing to minimize internal leakage.
5. Market-Proven
The Hanbell AB series has been successfully deployed in the market for over 15 years, earning an excellent reputation and delivering performance comparable to international brands.
