Commercial Kitchen Extraction Installation Kenya
The Cold Room Kahuna provides commercial kitchen extraction installation in Kenya, including kitchen extraction design, extraction fans, ductwork, kitchen hood connection, external air discharge and system installation.
We design and install extraction systems for restaurants, hotels, hospitals, schools, catering facilities, institutions and other commercial kitchens.
Unlike a kitchen hood supply page, this service focuses on the complete extraction and ventilation system.
Commercial Kitchen Extraction Systems
A commercial kitchen extraction system removes unwanted:
- Cooking smoke
- Heat
- Steam
- Grease-laden air
- Cooking vapours
- Odours
- Contaminated kitchen air
A typical system can include:
Kitchen hood → grease filters → extraction ductwork → centrifugal fan → external discharge
Depending on the building and system requirements, make-up or replacement air may also need to be considered.

Kitchen Extraction System Design
The extraction fan, hood and ductwork should be considered as one complete system.
We assess factors such as:
Cooking Equipment
Different cooking equipment produces different levels of heat, smoke, grease and vapour.
The system may serve:
- Fryers
- Grills
- Charbroilers
- Gas ranges
- Commercial cookers
- Ovens
- Woks
- Other high-temperature cooking equipment
Kitchen Hood
The hood dimensions and configuration affect the amount of air that needs to be captured.
For commercial kitchen hood fabrication and supply, see our commercial kitchen hood system page.
Required Airflow
The extraction system should provide sufficient airflow for the application and cooking equipment.
Static Pressure
The extraction fan must overcome resistance from components such as:
- Grease filters
- Ductwork
- Bends
- Transitions
- Dampers
- Discharge outlets
This is why fan selection should consider both airflow and static pressure.
Centrifugal Fans for Commercial Kitchen Extraction
Centrifugal fans are commonly considered for ducted extraction applications because the system may need to move air through filters and ductwork while overcoming system resistance.
We supply centrifugal fans and industrial blowers in Kenya for suitable ventilation and extraction applications.
View our centrifugal fan and industrial blower range for available specifications and applications.
For applications requiring higher system pressure, we can also provide high-pressure centrifugal fans subject to the required airflow and system design.
Fan selection is based on:
- Required airflow
- Static pressure
- Duct dimensions
- Duct length
- Number of bends
- Filter resistance
- Hood configuration
- External discharge arrangement
Commercial Kitchen Extraction Ductwork
Kitchen extraction ductwork connects the hood to the extraction fan and external discharge point.
The duct system can include:
- Straight duct sections
- Bends
- Transitions
- Vertical risers
- Access sections
- Fan connections
- Roof discharge
- Wall discharge
Duct dimensions and routing should be considered when selecting the extraction fan because the duct system contributes to the overall resistance.
External Kitchen Air Discharge
The extracted kitchen air needs to be discharged outside the building through a suitable termination point.
Depending on the building, this may involve:
- Wall discharge
- Roof discharge
- Vertical discharge
- External fan installation
- Weather protection
The discharge arrangement should be considered during the initial system design.
Fresh Air and Make-Up Air
A commercial extraction system can remove a significant volume of air from a kitchen.
For larger systems, make-up or replacement air may need to be considered to help maintain suitable pressure conditions within the building.
The appropriate approach depends on the building, extraction airflow and kitchen configuration.
Commercial Kitchen Extraction Installation Process
1. Site Assessment
We assess the kitchen layout, cooking equipment, hood location, available duct route and proposed discharge point.
2. System Design
The hood, extraction fan, ductwork and discharge arrangement are considered together.
3. Fan Selection
We select a suitable extraction fan according to the required airflow and system pressure.
4. Ductwork Installation
The extraction ductwork is installed between the hood, fan and external discharge point.
5. Fan Installation
The extraction fan is positioned according to the system design and available installation space.
6. External Discharge
The extracted air is discharged outside the building through the selected discharge arrangement.
7. Testing and Commissioning
The completed extraction system is checked to confirm that the equipment is operating correctly.
Commercial Kitchen Extraction for Restaurants
Restaurant kitchens may have several cooking appliances operating simultaneously.
A properly designed extraction system can help remove:
- Cooking smoke
- Heat
- Steam
- Grease-laden air
- Cooking odours
The fan should be selected according to the actual system requirements rather than simply choosing a fan based on free-air airflow.
Kitchen Extraction for Hotels
Hotel kitchens can have large cooking lines and extended operating periods.
Extraction systems may include:
- Large kitchen hoods
- Multiple extraction points
- Centrifugal extraction fans
- Long duct runs
- Roof-mounted or external fans
- Fresh-air provisions
Kitchen Extraction for Institutions
We also provide extraction solutions for:
- Hospitals
- Schools
- Universities
- Staff kitchens
- Industrial canteens
- Catering facilities
- Large institutional kitchens
Commercial Kitchen Extraction Installation Cost in Kenya
The cost of a commercial kitchen extraction system depends on the complete project specification.
Important factors include:
- Kitchen size
- Hood dimensions
- Cooking equipment
- Required airflow
- Static pressure
- Fan capacity
- Duct dimensions
- Duct length
- Number of bends
- Installation height
- Roof or wall discharge
- Fresh-air requirements
- Electrical requirements
For this reason, complete kitchen extraction projects are normally quoted according to the specific site requirements.
Kitchen Hood vs Complete Kitchen Extraction System
A kitchen hood is one component of a complete extraction system.
Kitchen hood:
Captures contaminated air above the cooking equipment.
Grease filters:
Help remove grease particles from the extracted air.
Extraction ductwork:
Carries the extracted air away from the hood.
Extraction fan:
Provides the airflow required to move air through the system.
External discharge:
Discharges the extracted air outside the building.
This is why the hood, fan and ductwork should be considered together when designing a commercial kitchen extraction system.
Kitchen Extraction Repairs and Maintenance
Existing kitchen extraction systems can require maintenance or equipment replacement.
Our services can include:
- Extraction fan repairs
- Centrifugal fan replacement
- Motor replacement
- Bearing replacement
- Electrical checks
- Ductwork repairs
- Grease filter replacement
- Airflow assessment
- Preventive maintenance
- Extraction system upgrades
We can assess existing systems where extraction performance has reduced or equipment requires replacement.
