1. Driven by an AC motor with a voltage of 220V and a power of 115W, it provides powerful power to meet most industrial ventilation needs.
2. The impeller's insulation is rated F or B, ensuring the motor's insulation performance even in relatively harsh electrical environments, enhancing equipment safety.
3. The main body is available in sizes ranging from 133 to 190 mm, with a compact and practical design that easily fits within various industrial ventilation system spaces.
4. The dual-inlet forward-facing design allows for more efficient air intake, improving both volume and uniformity.
5. It can be used to remove exhaust gas and dust generated during the production process, introduce fresh air, improve workshop air quality, and create a healthy working environment for workers.

What Causes Blower Impeller Noise and Vibration? The abnormal noise or vibration in a blower impeller is most commonly caused by physical imbalance (over 70% of field service cases), followed by bearing failure, loose mounting, or foreign object debris. If the impeller is not perfectly balanced, even a slight weight d...
