Frequently Asked Questions
How do I select the right fan model based on the parameters?
You should primarily look at the "Traffic (m³/h)" for the volume of air you need to move and the "Total Pressure (Pa)" to overcome resistance in your duct system. Match these requirements with the corresponding motor power (kW) and speed (r/min) options in our specification table.
What is the difference between 220V and 380V options?
Models like 2.5A to 3.5A support dual-voltage configurations (220V/380V), making them suitable for both single-phase and standard three-phase industrial supplies. Larger models (from 4A to 6A) operate exclusively on 380V three-phase power to ensure stable performance and energy efficiency for higher power loads.
Can these fans run at 60Hz frequency?
The standard specifications listed are rated for 50Hz. If your local power grid operates at 60Hz, please contact us prior to ordering. We can customize the motor configuration to ensure safe and efficient operation under 60Hz power supply.
What does the dual speed listing (1450 r/min vs 960 r/min) mean?
Certain models, like the 4A and 4.5A, offer configurations with different motor poles. The 1450 r/min motor provides higher airflow (traffic) and pressure but consumes more power. The 960 r/min motor operates at a lower speed, reducing noise and power consumption while providing moderate airflow.
Are customized sizes or materials available?
Yes, we offer customization options. Depending on your operational environment (such as high temperature, corrosive gases, or explosive atmospheres), we can construct the fans using stainless steel, fiberglass, or explosive-proof motors to match your specific needs.
