Failure to comply with these regulations can result in fines, closure of the establishment, or even legal consequences. An effective extraction system helps maintain compliance and ensures a safe and legal operation.

Lastly, a commercial kitchen extraction system enhances the efficiency of the kitchen. By removing heat and steam produced during cooking, the system helps maintain a comfortable working environment. This allows kitchen staff to work more efficiently and comfortably, ultimately leading to smoother operations and better productivity.

Components of a Commercial Kitchen Extraction System

A commercial kitchen extraction system is composed of several key components that work together to effectively extract and filter pollutants.


The canopy is a crucial component of the extraction system. It is installed over the cooking area and serves as the primary point of capture for smoke, steam, and grease particles. The canopy is designed to cover the entire cooking area and effectively channel the pollutants towards the extraction hood.

Extraction Hood

The extraction hood is responsible for capturing and directing the contaminants towards the extraction system. It is typically positioned directly below the canopy and is designed to have a larger capture area than the canopy. This ensures that smoke and grease particles generated during cooking are effectively captured and directed towards the filtration system.

Grease Filters

Grease filters play a vital role in trapping grease particles and preventing them from entering the extraction system. These filters are typically located inside the extraction hood and are made of materials like stainless steel or aluminum mesh. They require regular cleaning or replacement to maintain their effectiveness in trapping grease particles.


Ductwork refers to the system of pipes and conduits that transport the extracted air from the extraction hood to the outside of the building. It is essential for maintaining the airflow and ensuring that the pollutants are effectively expelled from the kitchen. Ductwork is typically made of galvanized steel or stainless steel to withstand high temperatures and grease buildup.

Extractor Fan

The extractor fan, also known as the exhaust fan or blower, creates the required airflow to extract and remove the pollutants from the kitchen. It is located at the end of the ductwork and is responsible for pulling air through the entire extraction system. Extractor fans can vary in size and power depending on the size of the kitchen and the volume of pollutants generated.

Fire Suppression System

A fire suppression system is an important component of a commercial kitchen extraction system. It is designed to detect and extinguish kitchen fires quickly and effectively. This system typically includes heat or flame detectors, fire suppression agents like wet or dry chemical systems, and an alarm system to alert staff and authorities in case of a fire emergency.


Purpose of the Canopy

The canopy serves multiple purposes in a commercial kitchen extraction system. Its primary function is to capture and contain smoke, steam, and grease particles produced during cooking. By covering the cooking area, it ensures that the pollutants generated during the cooking process are directed towards the extraction hood and filtration system, preventing them from spreading to other areas of the kitchen.

Materials Used in Canopy Construction

Canopies are typically constructed using stainless steel. This material is preferred due to its durability, resistance to heat and corrosion, ease of cleaning, and compliance with sanitation standards. Stainless steel canopies are also aesthetically pleasing and can be customized to fit the design and layout of the kitchen.

Design Considerations for a Canopy

When designing a canopy, various factors need to be considered to ensure its effectiveness. One crucial factor is the size of the canopy, which should adequately cover the cooking area to capture all the pollutants. The height of the canopy should also be appropriate to accommodate the cooking equipment and provide sufficient clearance. Additionally, the canopy design should include grease collection troughs and drains to facilitate easy cleaning and grease removal.

Extraction Hood

Function of the Extraction Hood

The extraction hood is a vital component of the commercial kitchen extraction system. Its function is to capture and channel contaminants from the cooking area towards the filtration system. By having a larger capture area than the canopy, the extraction hood ensures that smoke, steam, and grease particles are effectively captured and prevented from spreading throughout the kitchen.

Types of Extraction Hoods

There are various types of extraction hoods available, each designed to suit different kitchen layouts and cooking styles. Some common types include wall-mounted hoods, island hoods, and corner hoods. Wall-mounted hoods are attached to the wall behind the cooking equipment, island hoods are suspended from the ceiling above an island or a free-standing cooking range, and corner hoods are designed to fit in the corner of the kitchen. The choice of extraction hood depends on the kitchen layout, cooking equipment, and specific requirements of the establishment.

Selection Criteria for an Extraction Hood

When selecting an extraction hood, several factors need to be considered. The size of the hood should match the cooking equipment to ensure efficient capture of pollutants. It is important to consider the airflow requirements and select a hood with an appropriate capture velocity to effectively capture and extract contaminants. The material of the hood should be durable, easy to clean, and compliant with sanitation standards. Additionally, noise level considerations should be taken into account, especially if the kitchen is located in close proximity to dining areas.

Grease Filters

Role of Grease Filters in a Commercial Kitchen Extraction System

Grease filters play a crucial role in removing grease particles from the extracted air. As the air passes through the filters, the grease particles adhere to the filter media, preventing them from entering the ductwork and potentially causing blockages or fire hazards. Grease filters are indispensable in maintaining a clean and efficient extraction system.

Different Types of Grease Filters

There are primarily two types of grease filters used in commercial kitchen extraction systems: baffle filters and mesh filters. Baffle filters are constructed with multiple layers of metal baffles that change the direction of the airflow, causing the grease particles to impact and collect on the baffles. Mesh filters, on the other hand, are made of a fine mesh material that traps the grease particles as the air passes through. Both types of filters have their advantages and considerations. Baffle filters are more efficient in trapping grease and require less frequent cleaning, whereas mesh filters are easier to clean and maintain but may require more frequent replacement.

Maintenance and Cleaning of Grease Filters

Regular maintenance and cleaning of grease filters are essential to ensure their effectiveness. Grease filters should be cleaned or replaced regularly, depending on the level of grease accumulation. Cleaning can be done manually by soaking the filters in a degreasing solution or by using a dishwasher. It is important to follow the manufacturer’s instructions for cleaning and maintenance to prolong the life of the filters and maintain optimal efficiency.
