The Ultimate Guide to Choosing the Right Commercial Kitchen Hood System

A commercial kitchen hood system plays a critical role in maintaining a safe, clean, and effective working environment, serving as the first line of defense against fire hazards, air quality issues, and compliance concerns. As a cornerstone of any successful commercial kitchen operation, it is essential to understand the various types of hood systems available, their features, and how to select the right hood system that best suits your establishment's needs and requirements.

In this comprehensive guide, we will delve into the world of commercial kitchen hood systems, providing you with the knowledge and insights necessary to make informed decisions when setting up or upgrading your exhaust and ventilation infrastructure. 

By considering these essential aspects when selecting your commercial kitchen hood system, you can ensure a safe, efficient, and code-compliant work environment for your staff and guests alike. So, let us embark on this journey of exploration and equip you with the necessary tools to make an informed decision when it comes to your commercial kitchen hood system.

Types of Commercial Kitchen Hoods

There are two primary types of commercial kitchen hood systems, each designed to accommodate specific cooking operations and requirements.

1. Type I Hoods: These hoods are designed for use with grease-producing cooking equipment, such as fryers, griddles, and charbroilers. Equipped with grease filters, Type I hoods efficiently capture airborne grease and other combustion products, ensuring a safe and compliant work environment. Type I hoods are required by the National Fire Protection Association (NFPA) and local regulations for venues with grease-generating appliances.

2. Type II Hoods: Utilized in commercial kitchens without significant grease-producing equipment, Type II hoods capture steam, heat, and light-duty smoke produced by ovens, dishwashers, and steam tables. These hoods help maintain a comfortable and safe kitchen environment, but are not suitable for handling heavy grease-laden air.

Before choosing a commercial hood system, it is crucial to assess your kitchen's specific needs, equipment, and cooking processes to determine the appropriate hood type required for your establishment.

Sizing and Installation Considerations

Selecting the proper size and installation configuration for your hood system is critical to ensure optimal performance, efficient ventilation, and code compliance. Here are some key factors to consider when determining the appropriate size and installation requirements:

1. Hood Size: Your hood should be large enough to effectively capture and contain the heat, smoke, and grease produced by your cooking equipment. In general, the hood should extend at least six inches beyond the edge of your cooking appliances on all sides. Consult with a professional to determine the precise dimensions for your specific kitchen setup to ensure optimal coverage and capture efficiency.

2. Hood Height: The height at which your hood is installed can significantly impact its performance, with higher installations requiring more powerful exhaust fans to maintain adequate air movement. NFPA guidelines typically recommend an installation height of 18 to 24 inches above the cooking surface, depending on the type of equipment in use.

3. Exhaust Fan Capacity: The capacity of your exhaust fan should be matched to your hood system and the specific ventilation demands of your kitchen. A professional can help you determine the appropriate fan capacity based on your kitchen's size, layout, equipment, and local regulations.

Features and Customizations

Many commercial hood systems offer additional features and customization options to improve the efficiency, safety, and aesthetics of your kitchen. Explore the various options available, such as:

1. Baffle Grease Filters: These filters, commonly used in Type I hoods, are designed to capture grease particles without restricting airflow. High-quality stainless steel baffle filters are easy to clean, long-lasting, and contribute to improved fire safety.

2. Make-Up Air System: This ventilation feature provides an inflow of fresh air to replace the contaminated air exhausted by the hood system, maintaining balanced air pressure, and preventing strain on exhaust fans or air infiltration problems.

3. Custom Hoods: Many manufacturers offer custom hoods tailored to your establishment's specific needs and design preferences. Customizations can include specialized materials, finishes, sizing, or aesthetic features to seamlessly integrate the hood with your kitchen's design.

Maintenance and Cleaning

Routine maintenance and cleaning are crucial components of a well-functioning and safe commercial hood system. Key aspects of maintenance and cleaning include:

1. Regular Hood Cleaning: Engage professional hood cleaning services like Rujo Hood Cleaning to remove grease, debris, and potentially flammable material from your hood system. Regular hood cleanings improve efficiency, maintain compliance with local fire regulations, and reduce the risk of fire hazards in your commercial kitchen.

2. Filter Maintenance: Clean or replace filters as needed to ensure proper airflow and grease capture. Regular filter maintenance prolongs the lifespan of your filters and allows for efficient exhaust system operation.

3. System Inspections: Conduct periodic inspections of your hood system to identify potential issues or maintenance needs, such as malfunctioning exhaust fans or damage to the hood components. Addressing these issues promptly helps maintain your system's performance and safety.

Local Regulations and Compliance

Understanding and adhering to local regulations and industry guidelines governing commercial kitchen hood systems is essential for maintaining a compliant and safe establishment. Ensure compliance by:

1. Familiarizing Yourself with NFPA and Local Guidelines: Familiarize yourself with the NFPA guidelines and local fire safety regulations pertaining to hood systems, installation, cleaning intervals, and maintenance requirements.

2. Working with Licensed Professionals: Collaborate with licensed professionals for hood system installation, maintenance, and cleaning to ensure all work is carried out per relevant codes and regulations.

3. Regular Inspections and Record Keeping: Keep accurate records of cleaning, maintenance, and inspections to demonstrate compliance with regulations during audits or inspections.


Selecting the right commercial kitchen hood system requires a thorough understanding of the various types, features, and options available, along with consideration of your establishment's specific needs and requirements. By focusing on these essential aspects, you can create a safe, efficient, and code-compliant work environment for your staff and guests.
