What is a kitchen exhaust fan?

Your kitchen exhaust is a fan above the stovetop that removes the airborne cooking byproducts from the air in your kitchen. These byproducts can include grease, rogue spices, fumes, smoke, steam, and heat. While critical to your home kitchen, commercial kitchen exhaust fans are a necessary safety measure – as they often include fire suppression devices to vent and extinguish fires.

How Do kitchen Fans Work?

There are two types of kitchen exhaust fans systems, ductless and ducted. Ducted hoods are the most common. True to their name, they have a duct that the air gets sent through. These are popular in both homes and commercial kitchens. Ductless hood suck in the air, filter it and send it back into the room. Let's explore both of them below:


Ducted

There are a few essential components to a ducted kitchen exhaust fans system. These include:

Hood: The hood is the most recognizable part of the system. This floats above the stovetop and houses the kitchen exhaust fans and filter.

kitchen exhaust fans: Located inside the hood, the kitchen exhaust fans sucks the air through the filter and into the system

Honeycomb filter: Located inside the hood, filters grease particles and other byproducts

Ducts: Ducts are like a tunnel for the air to transfer outside the building. 

Ozone generator: Located inside of the ducts, the ozone generator cleans the air before it leaves the duct.

Lights: You can usually find these under or next to the hood to make seeing your culinary creations even easier


So, let’s say that you start cooking dinner and after a while, your kitchen is warm, steamy, and smells delicious. Little do you realize, there are also hot grease particles in the air, and like heat, rises a little bit.

You turn on the kitchen exhaust fans. The steam and grease particles get sucked up into the bottom part of the hood. Within that hood, there are honeycomb filters that trap the large grease particles.  The rest of the air flows into the kitchen exhaust fans duct. In some commercial kitchens, an ozone generator cleans the air and an aero vent kitchen exhaust fans pulls the freshly cleaned air the rest of the way through the duct and out onto the street or rooftop. 


Ductless

A ductless kitchen exhaust fans system works differently than a ducted system, but they do have some similarities. Ductless systems will recirculate the air back into the kitchen instead of the outside, which is why they're sometimes referred to as recirculating range hoods. In a ductless system, a powerful motorized kitchen exhaust fans sits above the stovetop. When the switch is flipped, the kitchen exhaust fans sucks the air up through a vent and filter.
