ELI5: Explain Like I'm 5

Industrial fan

An industrial fan is a very big and powerful machine that helps to move air in large buildings and factories. Just like when you blow air out of your mouth with a straw, the industrial fan has blades that spin around really fast and move the air around. The fan can be turned on and off with a switch or remote control and it's usually really noisy!

Sometimes, the air in a factory or big building can get really hot, stuffy or dusty, and that's where the industrial fan comes in to help. It helps to cool us down, move the air around and get rid of all the dust and bad smells. Industrial fans come in different shapes and sizes, and they're used in many different places all around the world!
