Industrial exhaust fans, also known as commercial exhaust fans, are used in a multitude of locations. Whether you have a barn, hall, factory, workshop, shop, greenhouse, shed or any other type of space, they definitely come in handy. Below are a range of products that show the best exhaust fans you can buy. Reviews are also a great indicator about the true operation of the fan and are highlighed with each fan. This page shows a whole range of different exhaust and shutter fans: some have have automatic shutters, some run quieter, and some push around huge air so you can choose one that's right for you.
These exhaust fans are used to control the interior environment by taking out particulates, odours, moisture, smoke and other pieces of matter which may be in the air. These fans act to primarily take matter, such as dust or gas and remove it to an external space. These fans can also be implemented into systems for heating and cooling. While regular fans can be used in more domestic applications, the industrial variety are used for larger spaces. They typically need more power, are larger and can apply larger exhaust capacity.
For example, exhaust fans are used in some woodwork shops to ensure the sawdust and other fine particles are removed from the environment so people don't inhale the particles. These may also be installed in residential type places, to be used as a fan, or exhaust system in a building's attic, used to circulate air in the building or home. They can sometime sometimes be confused with attic ventilators, which just exhausts hot air from the attic to the outside though an opening (unpowered). Restaurants rely on exhaust fans to keep their kitchens clear of smoke or fumes from cooking.
