Technical Specifications    

Key Product Features    
1. 300 PPM High-Volume Aircraft Starting Air Supply    
The HFASU300 aircraft air start unit provides 300 PPM air flow with adjustable starting air pressure from 2.4 to 2.9 bar / 35 to 42 psi, supporting stable aircraft engine starting operations.    
2. Reliable Cummins Diesel Engine    
The unit is equipped with a 500 kW Cummins diesel engine, offering strong power output, stable performance, and reliable operation for intensive airport ground support work.    
3. Heavy-Duty ISUZU Chassis    
The HFASU300 airport ASU is mounted on an ISUZU QL1100A8KAY chassis, providing good mobility, reliable apron driving performance, and easy positioning near aircraft service points.    
4. Oil-Free Double-Screw Rotary Compressor    
The air start unit adopts an air-cooled, oil-free, double-screw rotary compressor, helping provide clean, stable, and high-volume compressed air for aircraft ground service.    
5. Stable Constant-Pressure Air Control    
The constant-pressure air control system helps maintain stable air supply pressure during aircraft starting, improving operating safety and engine-starting reliability.    
6. Low-Noise Enclosed Housing    
The fully enclosed structure uses sound-absorbing materials, optimized intake and exhaust air ducts, intake louvers, and rear noise-reduction chambers to reduce operating noise and improve heat dissipation.    
7. Automatic Energy-Saving Speed Regulation    
During aircraft starting or auxiliary air supply, the HFASU300 can automatically adjust engine speed according to air flow demand, helping reduce fuel consumption, operating noise, and unnecessary engine load.    
8. Comprehensive Safety Protection System    
The HFASU300 includes multiple protection functions for aircraft and equipment safety, including pressure protection, engine protection, compressor protection, charging protection, and emergency stop.
