Industrial Exhaust Fans with High CFM

Table of Contents

    Commercial exhaust fans

    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. Reviews are included below the product for your convenience. A table at the bottom of this page shows a large selection of fans ordered by CFM, so you can easily choose the right fan for your application. Refer to the table of contents for easier navigation.

    Uses of Industrial Exhaust Fans

    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.

    Warehouse Ceiling Fans and other big ceiling fans

    If you’re looking for something to place on the ceiling to circulate air or cool down your area, look at our page about large industrial ceiling fans. These may be suitable for your for factories, garages, warehouses, and retail stores. There is also more information about high CFM ceiling fans here.

    Wall mounted exhaust fans

    The best exhaust fans are the wall mounted kind. These fans sit in a hole in the wall, and, as described above, remove the particles in the air from one side to the other.

    High CFM exhaust fans

    Industrial fans have high CFM. CFM stands for Cubic feet per minute, and is a measure of air flow that can be extracted by the fan. The higher this flow rate is, the faster contaminated air can be extracted to the outside. It is recommended that a high CFM is used for industrial purposes as safety can be a large concern. Generally, high CFM exhaust fans are better. Electronic circuitry provides the initial torque needed to start up the large fan blades for this high CFM. A higher CFM in a smaller area will just mean that the space will be refreshed more often.

    Warehouse exhaust fans

    Many of the exhaust fans on this page are suited specifically for warehouse applications. Some have very big CFM capabilities which might be great for your shop application, barn or warehouse. Industrial wall exhaust fans should have the appropriate CFM rating (and dimensions) for your sized space. If you need a basic outline in order to select a basic warehouse ventilation system, continue reading into the next paragraph which helps you select a commercial exhaust fan.

    What CFM do I need?

    Generally, the bigger CFM the better. Some exhaust fans here also include different speed motors, so you can be flexible about choosing that particular model. There are different methods to calculate what different exhaust cfm you need. As a general rule of thumb, you’ll need about 0.1 to 1 CFM per square foot of space for your application. The lower end (0.1 CFM per sq.ft) is for cleaner, less moist environments. The higher end (1 CFM per sq.ft) would apply to stuffy, hot and moist or dirty areas like garages, offices and warehouses. If in doubt, pick a higher CFM. I’ve also made a handy CFM calculator that you can use to obtain an estimate for your application here.

    This CE 10-DS is a single phase 10-inch diameter direct drive exhaust fan. It has a built-in shutter mechanism and is a great fan for interfacing with the outside.

    The blade system (steel hub and spider) holds three aluminum paddles. These paddles are enclosed by front steel spiral wire guards for higher durability and strength. The built-in shutter mechanism allows the fan to be installed from inside, which is a huge plus. External framing isn’t needed, and the self-closing shutters protect the fan from the elements (such as rain and snow) when not in use. This fan can also run at variable speeds thanks to the permanent split capacitor. The motor of the CE10-DS exhaust fan is fully sealed, making it suitable for use in conditions that regular motors are not suited for, such as around dust.

    The best industrial exhaust fans

    The following are a selection of different industrial exhaust fans with different CFMs. If a fan has more than 1 speed, it is less powerful overall (in general, but more versatile). I recommend purchasing a fan with different speeds as it is more likely to suit your needs should they change. Use our industrial CFM exhaust fan calculator to get the best fan for you..
