AOSIF silent generator is designed by professional

acoustic engineers based on 11 years experience, Now

we can make the noise of the generator less than 80-

85dB(A) at 1m, or 70~75dB(A) at 7m, 60~65dB(A) at

15m.★ multi-way air intake and exhaust guarantee the

power performance of the generator.

★large-scale impedance combined type silencer

effectively reduce noise of the generator.

★ internal high performance rubber damper and

flexible materials reduce vibration.

★ Base mounted fuel tank supports the generator

running for 8 hours.

★Transparent viewing window make the control panel

clear at a glance.

★Emergency stop button mounted on the canopy

exterior for urgency.

★Cooling fluid injection hole is kept on the ceiling crust.

★ Cold steel materials of the canopy.

★ Best powder paint.

★ Zinc plated and Corrosion resistance.

★ Elegant appearance and reliable quality.
