Energy saving and environmental protection

low noise

Unique noise and vibration control technology ensures that AIRMAN generators can provide you with a quiet working and living environment. It is the designated model of "Ultra-low noise construction machinery" (below 220KVA) and "Low noise construction machinery" (300-500KVA) by the Ministry of Land, Infrastructure, Transport and Tourism of Japan.

Low tailpipe emissions

SDG13S/25S is a designated model of "Construction machinery for tertiary emission countermeasures" by the Ministry of Land, Infrastructure, Transport and Tourism of Japan. SDG25AS~500S is a designated model of "Construction machinery for secondary emission countermeasures".

Low fuel consumption

It adopts a high-quality energy-saving engine to minimize the burden on users and reduce their usage costs.

High security, high performance

Equipped with safety protection device

The engine is equipped with an emergency stop circuit as standard, which completely eliminates the risk of electric shock when restarting. It is also equipped with a leakage protector as standard. In the event of leakage, both the three-phase circuit breaker and the single-phase circuit breaker will be cut off.

Excellent power generation performance

The high-performance generator has a voltage fluctuation rate within ±0.5% and a speed fluctuation rate within 5%. Equipped with sufficient damping coils, the voltage fluctuation deformation is very small, and it can be directly used as a power source for variable frequency loads, thyristor rectifiers, computers, precision machinery, and precision testing instruments.

Fully equipped

Dual Voltage Standard Specification

By switching the connection board in the control panel, you can easily change the output voltage from 200/220V to 400(380)/440V. When you start the engine, the three-phase output voltage indicator on the operation panel lights up, and you can see the voltage being used at a glance.

External oil supply

It can be easily connected to an external fuel tank for long-term continuous operation. A new single-handle three-way conversion valve is adopted, which can achieve one-time switching without worrying about misoperation.

Automatic vacuum device

By pressing the fuel pump-out switch on the operating panel, the pump-out electromagnetic pump automatically exhausts the air in the fuel circuit, eliminating the tedious work of operating a manual pump.

Operational

Operation control panel

The components of the generator control system and the engine electrical control system are centrally installed in the control panel to give full play to the operability and overall performance.

1. Three-phase circuit breaker 9. Ammeter switch

2. Panel lighting 10. Leakage relay

3. Voltage indicator light 11. Start switch

4.Voltmeter 12.Fuel meter

5. Amperemeter 13. Water temperature meter

6.Frequency meter 14.Oil pressure meter

7. Light switch 15. Alarm indicator light

8. Voltage regulator 16. Speed control regulator

Inspection and maintenance

One-side inspection

Just by opening one side door of the machine, you can easily perform daily inspection items such as checking engine lubricating oil and cooling water.

Fuel tank is easy to disassemble and install

The flat plate design at the bottom of the fuel tank allows for easy disassembly and installation of the fuel tank, making it easy to remove the fuel tank for cleaning.

All-weather outdoor box structure

Strong environmental adaptability

It is suitable for long-term use in harsh outdoor working environments. In principle, it does not require foundation work and has a simplified, functional and sturdy box-type structure.

Windproof, rainproof and sunproof

The cabinet is made of unique powder coating, which will not fade even if exposed to the sun for many years.
