Find Your Commercial Kitchen Exhaust System: A How-to Guide

The kitchen exhaust system is an integral part of any commercial kitchen. It helps remove smoke, grease, and other pollutants from cooking. A good exhaust system not only keeps the kitchen clean but also ensures the safety of the staff and customers. This comprehensive guide will help you understand how to get the right exhaust for your commercial kitchen.

Types of Kitchen Exhaust Systems

There are two primary types of kitchen exhaust systems: canopy hoods and proximity hoods. Canopy hoods are the most common type. They are installed above the cooking equipment and capture the air and pollutants through a series of filters. Proximity hoods, on the other hand, are installed directly above the cooking equipment and use a high-velocity air stream to remove pollutants.

Choosing the Right Size of Exhaust Fan

The size of the exhaust fan will depend on the size of your kitchen and the amount of cooking equipment you have. As a general rule, the fan should be able to move the entire volume of air in the kitchen through the hood at least once every minute. The fan size will also depend on the type of cooking equipment you have. For example, if you have a lot of deep fryers, you will need a larger exhaust fan to remove the excess heat and grease.

Consider the Noise Level

The exhaust fan can be noisy, especially if it is located in the kitchen. It is essential to consider the noise level of the fan for your commercial kitchen exhaust installation. Look for models that have low decibel ratings to minimise the noise level in your kitchen.

Choose the Right Filters

The filters in your kitchen exhaust system play a crucial role in removing pollutants from the air. There are three types of filters: baffle, mesh, and charcoal. Baffle filters are the most common type and can effectively remove grease and smoke. Mesh ones are less effective at removing grease but are easier to clean. Lastly, charcoal ones are used to remove odours but are not effective at removing grease.

Consider the Ductwork

The ductwork in your kitchen exhaust system is responsible for carrying the air and pollutants outside. The ductwork’s size will depend on the exhaust fan’s size and the amount of airflow needed. It is essential to ensure that the ductwork is properly sized and installed to avoid any blockages or restrictions.

Installation and Maintenance

The installation of your kitchen exhaust system is critical to its effectiveness. It is essential to hire a commercial kitchen exhaust installation to ensure that it meets all safety and building codes. Once installed, it is crucial to maintain it regularly to ensure its effectiveness. This includes cleaning the filters, ductwork, and fan blades regularly.


Choosing the right kitchen exhaust system is crucial for any commercial kitchen. It helps to maintain a clean and safe environment for the kitchen staff and customers. When choosing the right system, consider the type of hood, size of the exhaust fan, noise level, filters, ductwork, and installation and maintenance. By following these guidelines, you can trust that you’ll have a smooth commercial kitchen exhaust installation.
