Structural Design for Long-Term Stability
-
Frame & Impeller: High-strength engineering plastic
-
Bearing System: Dual ball bearings for long operational life
-
Motor Type: Brushless DC motor
-
Compact thickness: Only 10.5 mm
This structure provides low vibration, low noise, and high mechanical stability, even under continuous 24/7 operation.
Intelligent Control & Signal Options
To meet different system integration needs, 7010A supports multiple intelligent control functions:
| Code | Function |
|---|---|
| 0 | No function |
| 1 | PWM speed control |
| 2 | High-level fault alarm |
| 3 | Tachometer (RPM feedback) |
| 4 | PWM + fault alarm |
| 5 | PWM + tachometer |
These features allow precise airflow control, real-time monitoring, and predictive maintenance, which are essential in industrial automation and mission-critical systems.
Military-Grade Environmental Adaptability (GJB Standards)
