1. Efficient airend
There is no intermediate transmission, so there is no energy loss; direct drive increases reliability and reduces maintenance costs; large rotors run at low speeds, with higher efficiency, lower noise, lower vibration, and lower energy consumption.

2. High-quality independent oil pump forced lubrication design
(1) Forced lubrication with independent oil pump;
(2) Ensure that there is sufficient fuel injection and a better air-fuel mixture ratio under extremely low exhaust pressure (2kg).

3. Increase customized oil and gas separation system
Increase the customized oil and gas separation system to ensure the ultimate oil and gas separation effect and ensure that the oil content of the air is less than 3ppm.     Technical Parameters
