Know Your Commercial Kitchen Ventilation Hoods

Commercial kitchen ventilation hoods, often referred to as exhaust hoods or range hoods, are essential components of any professional kitchen. They play a crucial role in maintaining a safe and comfortable kitchen environment by removing smoke, grease, odours, and heat generated during cooking. Here are some key aspects of commercial kitchen ventilation hoods.


Types of Hoods

Wall-Mounted Hoods

These are mounted on the wall above the cooking equipment.

Island Hoods

These are suspended from the ceiling and are typically used for kitchen islands.

Under Cabinet Hoods

These are installed under cabinets above cooking appliances.

Downdraft Hoods

These are designed to retract into the countertop when not in use, and rise to capture cooking fumes when needed.


Ventilation hoods have several parts. Not all are included in every system. These include:

Hood Canopy

The part of the hood that captures and contains cooking fumes.

Grease Filters

These capture grease particles to prevent them from entering the ventilation system.

Exhaust Fan

This draws in air and cooking odours and directs them through the ductwork, away from the kitchen and dining areas.

Exhaust Ductwork

This transports the grease and odour laden air outside the building.

Make-up Air System

This provides fresh air to replace the exhausted air, maintaining proper air balance.

Exhaust System Design

Properly designed ventilation systems must match the cooking equipment’s heat and pollutant output. The hood’s size, airflow capacity, and exhaust fan power should be suitable for the kitchen’s cooking load. It also obviously has to comply with local legislation. The exhaust ductwork should be sealed and insulated to prevent heat loss and condensation.

Codes and Regulations

Compliance with local building codes, health department regulations, and fire safety standards is essential. Regular maintenance and cleaning are required to prevent grease buildup and fire hazards.

Fire Suppression

Some commercial kitchen hoods may be equipped with fire suppression systems designed to automatically extinguish grease fires in the hood.

Ventilation systems can be noisy, so noise control measures are often needed to maintain a comfortable kitchen environment for staff and customers.

Energy Efficiency

Energy-efficient ventilation hoods and fans can help reduce operating costs and environmental impact.

Ventilation Planning

Proper kitchen ventilation design involves consulting with HVAC professionals to ensure efficient airflow and safety. The hood should be located to capture pollutants effectively and provide comfortable working conditions for kitchen staff.


Regular cleaning of grease filters and ductwork is crucial to prevent fire hazards and maintain optimal ventilation performance.


Correctly sizing the ventilation system for the kitchen’s needs is crucial. Oversized hoods can lead to unnecessary energy consumption, while undersized hoods may not effectively capture cooking fumes.

Commercial kitchen ventilation hoods are critical for ensuring a safe and comfortable working environment, complying with regulations, and maintaining the quality of food and customer experience in restaurants, hotels, and other food service establishments. Consulting with professionals who specialize in kitchen ventilation is often necessary to design, install, and maintain an effective system.


Commercial Ventilation Hood

Commercial Ventilation Hood

This is often referred to as a commercial kitchen hood or exhaust hood and is an essential piece of equipment used in commercial kitchens and food service establishments. Its primary purpose is to remove heat, smoke, steam, grease, and odours generated during cooking processes. These hoods are designed to maintain a safe and comfortable environment in the kitchen and ensure compliance with health and safety regulations.

Key features and functions of a commercial ventilation hood include extraction, filtration and exhaust, that is, drawing in the used air, filtering to remove grease and finally exhausting it to the outside, away from the kitchen and dining areas.


Commercial hoods are equipped with powerful fans that draw in air from the cooking area, capturing smoke, heat, and grease particles.


Air is typically filtered to remove grease and particulate matter using metal baffle filters or mesh filters.


The captured air is then channeled through a network of ducts that lead to the exterior of the building. This ductwork allows for the safe expulsion of contaminants outdoors.


The exhaust system helps maintain a comfortable and safe working environment by removing hot and polluted air from the kitchen, which prevents overheating and the accumulation of harmful substances.

Fire Suppression

Many commercial hoods incorporate fire suppression systems, such as automatic fire extinguishers or fire suppression nozzles, to protect against kitchen fires.


Commercial kitchens are often required to meet specific ventilation standards and regulations, ensuring a safe and healthy workspace. Commercial ventilation hoods are designed to help establishments meet these requirements. Ventilation hoods come in various sizes and configurations, with choices ranging from simple canopy hoods to more complex, custom-designed systems for specific kitchen setups. The choice of a hood depends on the size of the kitchen, the types of cooking equipment used, and local building codes.

Proper maintenance and cleaning of commercial hoods are crucial to ensure their efficiency and prevent fire hazards. Regular inspections and professional cleaning services are often necessary to keep the system functioning optimally.


Commercial ventilation hoods are important for several reasons in a commercial kitchen or food service establishment.

Primary Tips For Choosing The Best Commercial Range Hood

When you are starting up or upgrading your commercial kitchen, you want to focus on finding the right commercial extraction system. Finding the right exhaust hoods can make a significant difference in your kitchen. Below, we will be going over some of the top tips for choosing the right commercial extraction canopy to purchase for your commercial kitchen.

Finding The Best Commercial Range Hood:

1. The Rate of Exhaust.

One of the most important things to look at and consider when you are shopping for industrial kitchen extraction systems for your commercial kitchen would have to be the exhaust rate that the commercial cooker hood is capable of achieving. This rate is defined by the amount of exhaust air that can be removed from your space. It is usually displayed or referred to in the number of cubic feet per minute or “CFM.” The overall rate that you will require if you have a commercial kitchen is going to depend on several factors. For one, it is going to depend on the amount of smoke, heat, and grease that is produced by the appliances that you are using and the food that you are generally cooking. For instance, if you are going to be frying a lot of foods, you are generally going to need a much more effective industrial cooker hood than a restaurant that serves a lot of vegetarian food. At the same time, restaurants that offer open-flame cooking are going to have much more smoke to exhaust. Thus, you need to factor in all of the above in order to figure out what kind of requirements you have in terms of exhaust rate.

2. Design.

Another major factor that you are going to want to consider when you are looking to purchase a new commercial extractor hood for your commercial kitchen would have to be the overall design and look of the hood. There are different designs and styles that you could opt for. The design that is likely going to interest you will depend on the other appliances that you have in the kitchen and their respective designs and materials. There are proximity hoods which are much smaller hoods that are typically mounted much closer to the appliance that you are looking to exhaust. There are different styles that you can choose from in this category. There are also wall mounted hoods that act as a canopy. These hoods are mounted directly to a wall and they are usually going to extend beyond the appliances that you are using overhead. Thus, they are going to be much bigger than the proximity hoods. The last option that you have available are island hoods which are meant to hang directly from the ceiling and they are usually used over a bunch of appliances that require exhaust that is in a straight line.

3. Different Types.

Another major thing that you are going to have to consider when you are shopping for commercial range hoods would be whether you need a type 1 or type 2 exhaust system.

Type 1 systems are designed to offer liquid-tight operation and these hoods even feature their own built-in fire prevention systems. Because of this, if your kitchen presents a fire risk, you will require one of these hoods. This means if you are cooking a lot of foods that generate grease and smoke.

Type 2 systems are primarily meant for appliances that either steam or bake. This is because these appliances are not going to present a fire hazard as they only generate moisture and heat. Thus, you can purchase a type 2 if you are only working with these appliances in your kitchen.

Overall, there are a lot of things that you will need to look at and consider when you are trying to figure out what commercial range hood to invest in for your kitchen. A lot is going to depend on what is in your kitchen already as far as appliances go, what your design is currently like, and whether or not you have specific exhaust requirements and safety concerns to address with the range hood. There are also ongoing costs to factor in, such as whether you will need commercial mesh grease filters. By figuring all of this out, you should be in a great position to find the right canopy extractor hoods for your commercial kitchen.

Commercial Ventilation Hoods

If you’re running a commercial kitchen, then it’s vital to install quality commercial kitchen ventilation hoods that can help you to keep your kitchen free of fumes, greasy air, and other contaminants.

A commercial enterprise needs a much larger cooker hood than any domestic situation in order to keep the air clean.

With this in mind, you’ll want to pay careful attention to the dimensions, power, and general configuration of the cooker hood and how it will fit in with your existing kitchen design.

Also, consider how the cooker hood is powered, as well as how this will affect the running costs of your commercial kitchen. It’s worth noting that you can purchase either gas or electric commercial range hoods, and the overall output of the cooker hood will be determined largely by the number of ovens you’re running and how long your kitchen is going to be in action for each day.

There may also be some ongoing running costs associated with your new hood, such as buying replacement filters and making sure it is regularly inspected to ensure it is functioning correctly. In some cases, mold can form within the duct, so this will be another key area that will need to be maintained regularly to ensure it is kept safe and clean. It’s also a good idea to learn more about how the range can be kept clean, and whether an external service is going to be needed every year to keep it in top running shape.

Furthermore, it’s wise to pay attention to any legal guidelines that dictate where your exhaust fumes are allowed to go. For example, you do not want to get into legal trouble due to smoke or odors contaminating the surrounding area, particularly if you are close to any residential premises. Fortunately, many of the best commercial ranges take this into account, and they will be able to filter out a large amount of waste, smoke, grease, or odor.

It’s also important to make sure that your chosen commercial range hood meets all of the legal guidelines for your environment.

At the end of the day, investing in a quality commercial range hood is an essential business investment for any serious kitchen. While these items can represent a significant upfront cost, they will go a long way towards making the kitchen more comfortable for your chefs and staff to work in, as well as ensuring that your kitchen is kept far cleaner than it otherwise would be if all of the smoke and grease was allowed to build up over time.
