What should we do if the air blowing distance of SDF series tunnel axial flow fan is too short?

If your SDF Series Tunnel Axial Flow Fan is struggling with short air blowing distances, it could be due to several common issues. Here are the most frequent causes and how to resolve them:

Incorrect Fan Model: Using the wrong fan model can significantly reduce the blowing distance. Always select the appropriate fan model based on the required air blowing distance for your specific project.

Wrong Duct Diameter: The diameter of the air duct plays a crucial role in airflow efficiency. Ensure that the duct diameter matches the fan’s air outlet size. The duct diameter should never be smaller than the fan’s outlet caliber.

Poor Duct Installation or Air Leaks: A poorly installed air duct or air leaks can cause airflow losses, reducing the blowing distance. Make sure the air duct is properly leveled, straightened, and tightened during installation. Remove any water accumulation inside the duct to minimize ventilation resistance. Regularly inspect the duct for any damage, and promptly repair any leaks or needle holes.

By addressing these common problems, you can optimize the performance of your SDF Series Tunnel Axial Flow Fan and ensure proper ventilation in your tunnel projects.
