As the distance between a fan and an obstruction decreases, the airflow tends to decrease and the noise level tends to increase.
Therefore, provide as much clearance as possible between the fan's air inlet/outlet and any obstruction, using the following guidelines as a reference.
Therefore, provide as much clearance as possible between the fan's air inlet/outlet and any obstruction, using the following guidelines as a reference.
Guidelines:
-
When an obstruction is located on the discharge side: About half the fan dimension
-
When an obstruction is located on the intake side: About two-thirds to the full fan dimension
* Notes:
- These values are provided for reference only.
The appropriate clearance depends on the equipment design and the fan model.
- Obstructions on the intake side have a greater effect on airflow performance.
Therefore, maintaining as much clearance as possible is recommended.
