When using industrial fans in a steel structure factory building, the coverage area depends on factors such as the fan diameter, building height, and layout design. Below is a reference for the coverage area of common diameter industrial fans:

1. Single Fan Coverage Area

• 7.3m diameter: covers approximately 1,000 square meters (ideal range: 800-1,000 square meters).
• 6.1m diameter: covers approximately 800 square meters (ideal range: 600-800 square meters).

• 5.5m diameter: covers approximately 600 square meters (ideal range: 500-600 square meters).

  
  

  

2. Coverage Area for Three Fans

If three fans are installed in a steel structure factory, the theoretical coverage area would be three times that of a single fan. However, due to overlapping airflows, the actual coverage area will be slightly less. The conservative estimates are as follows:

• 7.3m diameter: total coverage area approximately 2,400-2,700 square meters.
• 6.1m diameter: total coverage area approximately 1,800-2,100 square meters.
• 5.5m diameter: total coverage area approximately 1,500-1,800 square meters.

3. Evaluation for Suitable Factory Area

Based on the height of the factory and actual ventilation needs:

• For a factory area of 2,000-3,000 square meters, it is recommended to use 7.3m diameter fans.
• For a factory area of 1,500-2,000 square meters, it is recommended to use 6.1m diameter fans.

• For a factory area of 1,200-1,500 square meters, it is recommended to use 5.5m diameter fans.

  
  

  

Important Notes

• Fan Spacing: Fans should be spaced appropriately to avoid excessive overlap of airflow, which can reduce efficiency.
• Height and Obstructions: Ensure there are no obstructions that block airflow within the factory. The installation height of the fans should meet the minimum safety requirements.
• Professional Evaluation: It is recommended to contact the fan supplier (such as DHOO Technology) for an on-site evaluation to optimize the ventilation plan.
