Giant Fan

Frequently Asked Questions

How to choose the right size Giant Fan?

For industrial spaces, the size of the Gaint Fan is determined primarily by the volume of air that needs to be moved, which depends on the dimensions and ventilation requirements of the space. Other things like temperature, humidity, and the purpose of the space will also impact this decision. Speak to a member of Fanquip today, and we’ll help you choose the right size Giant Fan for your space and needs.

In what size space is each giant fan suitable for?

There is no proper guideline as to what size would fit the space, but, roughly:

• A 4.2m giant fan is suitable for medium spaces, often up to around 1000 m2, depending on ceiling height.
• A 5.5m giant fan would be used for large spaces 1500 – 2000 m2, like warehouses or production spaces.
• Our biggest size, the 7.3m giant fan is suitable for very large spaces or high-ceilinged areas over 2000 m2, usually for manufacturing plants.

Why does the speed of the fan decrease when the size increases?

The speed of a fan decreases as the size increases because larger fans move more air volume per rotation due to their greater blade surface area, allowing them to create powerful airflow without needing high speeds. Slower speeds also help to maintain structural stability, as high-speed rotations in large fans would generate excessive force, increasing wear and safety risks.
