Top 5 Best heavy duty exhaust fan for kitchen

1) iLiving – 24″ Wall Mounted Exhaust Fan

  • Good Airflow and quiet operation

The most important feature to consider in an exhaust fan is how much air it is able to move. With 1050 rotations per minute, the motor of this fan packs more than enough power to get the job done. The fan is also available in 8 different sizes, and of course, the larger the size, the longer the size of its blades, and the more air it would move. This motor is, however, able to cause an airflow of 4,244CFM, making it more than sufficient enough to serve 6,200sqft in space.

What is equally just as impressive is that its whole system is motion balanced for completely quiet operation. It is quiet even on the highest speed. This device would bring a good mix of performance and peace to your kitchen.

  • Excellent motor design

Asides the already mentioned high capacity and balanced motion design of the motor, which gives the fan a high airflow rate while being quiet, the motor also has other designs that give it impressive overall performance.

Firstly, it is fully enclosed; therefore, no foreign bodies like dust, sand or paint, will be able to get in, which prolongs the overall lifespan of the motor, and it is also thermally protected. This thermal protection prevents it from overheating that could ware out bearings faster. The motor is also permanently lubricated, making maintenance as easy as it gets.

  • Shutters and variable controller

For users who fancy more precise control, a variable speed controller can be purchased with this fan. This allows users to run the fan at lower speeds, instead of simply always running on the highest level. Note that the variable speed controller doesn’t come with the fan, and has to be purchased separately.

The shutters of a fan perform the major task of protecting it from foreign bodies. This fan’s shutters, however, takes it to the next level in being both corrosion and water-resistant.

As a result of this, it does not only prevent objects from getting into the fan but also moisture, while its corrosion and heat resistant nature ensures it doesn’t wear out over time. It is also very light in weight and automatically opens at the slightest movement of the blades of the fan.

  • very high Airflow of 4,244CFM makes it perform in areas up to 6,200sqft,
  • operates quietly,


  • doesn’t come with installation accessories,
  • speed controller does not contain the purchase package, therefore, has to be bought separately,

2) TPI Corporation Direct Drive Exhaust Fan

  • Airflow

Although the relatively small size of this fan might not give it away, or make it look like much, its airflow rate is actually impressive. Available in different sizes up to 30 inches, this TPI product impact can be enhanced by purchasing a larger model, which would have a larger fan.

This size, however, has an airflow rate of 3,950CFM, making it almost as good as the iLife product. With this large air volume moving every minute, it is able to exhaust a large area of up to 6000sqft, and we are pretty sure your kitchen isn’t half that size, but even if it is, then the fan is still more than able to get the job done.

  • Motor design

The motor of this product doesn’t exactly have any special design, but its overall setup makes us take a second look. Permanently sealed in a case for protection, this motor is able to function for a long time, without dust and other contaminations getting in, which effectively increases its life span.

The motor is also permanently lubricated; therefore, it wouldn’t require much maintenance and would run smoothly for years to come. This lubrication also increases its overall life span, allowing it to seamlessly operate without much wear to its bearing.

  • Speed controller

Unlike the iLife product, purchasing this fan comes with a variable speed controller that does exactly what its name implies; it controls the fan’s speed. The speed controller comes with three different control options to choose from; low, medium, and high. It allows more precise control over speed and is a major advantage since you don’t have to purchase the controller separately.

  • Shutters

In this fan, the shutters exist for two purposes; protecting the fan itself, as well as serving as a mounting frame for the fan. These self-closing shutters protect the fan from liquid splash and other external materials like dust and debris when it is not in operation.

The shutter also comes with something like a housing frame, which the fan is attached to, and this frame allows the user to easily mount, although the wall would have to be quite thin. The fan blades cages, on the other hand, meets safety standards and mounting mechanisms.

3) Broan-Nutone L300 High Capacity Ventilator Fan, Commercial Exhaust Fan

  • Fancy Design

This fan takes a different turn compared to others on our review list so far. It is for those on the fancy edge, and would rather give up a lump sum of performance for something that blends into a decoration, which is exactly what this fan is. Made with a good looking paintable exterior, this fan is housed by a steel casing on the interior side, which has an outlet that is to be connected to a duct.

As a result of this, it is not even close to remotely being as powerful as other heavy-duty fans in Airflow, as it only manages a 309CFM. It makes this list, however, for the purpose of diversification.

  • Permanently lubricated motor with steel casing

The fan’s motor is well protected and secluded in a steel casing, which would be on the other side of the house. This motor is connected to a duct, which his channeled to the outside environment, and as a result, protecting it from direct exposure to foreign bodies. The motor is also permanently lubricated, reducing required maintenance bare minimum, as well as ensuring a long life span.

  • Mounting options/ quiet operation

Mounting options accompanied with this product include either in a ceiling or on the wall. Either way, the impact of the motor shouldn’t be reduced, although its design makes ceiling mounting the more preferred option. Its permanently lubricated motor helps it operate very quietly, with a noise level of 2.9sones.


  • operates quietly at 2.9sones,
  • permanently lubricated low RPM motors,
  • fancy ceiling or wall-mounted design,


  • relatively low airflow rate of 309CFM,

 4) Powerful Industrial Exhaust Fan

  • Excellent motor

The standout features of this fan’s motor are in its fully enclosed and thermally protected design. Totally enclosed, the motor is protected from coming in contact with alien bodies, which are commonly found in the duct-like air path of the fan.

The debris getting in or not, could go a long way in deterring the motors life span. Asides this covering, overheating is another problem faced by fan motors, especially when it’s a fan that runs consecutively for so many hours. This fan’s motor is thermally protected to prevent overheating that could spoil the motor quicker.

  • Airflow

The most important quality of a fan, which is its airflow rate, is very good for this product. At 1,400CFM, this fan moves a large volume of air per minute and is suitable for fairly large-sized areas. It would surely do a kitchen lot of good, circulating the air regularly, depending on the kitchen’s size.

  • Durable housing

Made of galvanized steel, the housing (fan blades as well as the shutter) of the fan is very durable and would last for many years to come. This material is also rust-resistant, preventing it from wearing off over time when it has circulated moisture-filled air. Both the fan’s blades and shutters are made of this anti-rust galvanized steel.

Downsides of this fan include a noisy operation, which is accompanied by excessive vibrations while it operates. This vibration could cause the fan to become wonky in a short while, and not much desirable although still functional. It also doesn’t come with a speed controller.

Features to consider in choosing a heavy duty exhaust fan for kitchen

  • Shutters:

It is important that an exhaust fan possesses shutters that close and open on its own accord, depending on air movement. Shutters help protect the fan from the external environment, as well as prevent air from flowing the other direction in the fan.

They are a very useful feature, and purchasing a fan without would mean you have to purchase the shutters separately. We recommend the shutters also be made out of durable rust-resistant material.

  • Airflow rate:

There is a direct proportion between the air flow rate and the direct performance of the fan/ impact on the atmosphere of the kitchen. The higher the air circulation in CFM, the more fresh and clean your air would be. In the case of air flow rate, higher is always better, and you should go for the highest product that you can afford.

  • Noise level:

A kitchen is a place where you are going to spend considerable time in; therefore, it is important that the place is conducive, especially quiet enough for you to be fine in.

Let’s face it, exhaust fans would always come with some level of noise because of the amount of air moving, but that should be all. Stay away from products with excessive vibration or clanking sounds, or any other one order than moving air.

  • Speed controller:

Depending on the severity of need, the speed of an exhaust fan can be varied with a controller. Some products come with this device, while in others, it would have to be purchased separately. Buying a fan that already has a speed controller is the most favorable option.

  • Durability:

This cuts across the fan blades, as well as shutter materials. Top-quality products are made of rust-resistant materials like galvanized steel since air with high moisture content would be going through very often. A fan-made of cheap material would degrade faster.
