How Do You Size a Kitchen Extractor Fan Correctly?
Correct fan sizing determines whether a commercial kitchen extraction system meets Building Regulations Part F and CIBSE ventilation guidance. The standard approach calculates required airflow based on kitchen type, cooking appliance load, and hood capture area, with commercial kitchens typically requiring between 15 and 30 air changes per hour depending on cooking intensity.
Key sizing inputs include the kitchen volume (m³), the type and BTU output of cooking appliances, duct run length, number of bends, and any grease filter static pressure losses. Under-sizing leads to poor capture, condensation, grease accumulation in ductwork, and potential non-compliance with fire safety requirements; over-sizing wastes energy and can create negative pressurisation problems that reduce extraction effectiveness.
For specifiers, manufacturers' fan selection tools and BESA DW/172 guidance are the appropriate starting points and for complex projects, involving a specialist HVAC engineer at the design stage prevents costly remediation later.
What Fan Types Are Used in Commercial Kitchen Extraction?
Commercial kitchen extraction systems draw on several fan architectures, each with distinct performance characteristics suited to different project requirements.
-
Inline centrifugal duct fans — sit within the duct run, generate good static pressure, and keep noise away from the kitchen; suitable for most commercial kitchen configurations
-
Axial plate fans — high-volume, lower-pressure units often used for short, straight extract routes where duct resistance is minimal
-
Mixed flow fans — combine axial and centrifugal design principles; good pressure-to-airflow ratio in a compact body, well-suited to smaller commercial kitchens
-
Roof-mounted extract fans — used where duct routing exits vertically through the building; discharge directly at roof level
-
Twin fan units — provide built-in redundancy for critical extraction applications such as large restaurants or healthcare catering facilities
-
High-temperature fans — specified where extract air temperatures exceed standard fan motor ratings, typically in proximity to commercial cooking equipment

Frequently Asked Questions
What is the minimum extraction rate for a commercial kitchen?
Commercial kitchens typically require between 15 and 30 air changes per hour, depending on appliance load and kitchen type. CIBSE Guide B and BESA DW/172 set out the detailed calculation methodology, these figures should be confirmed by a ventilation engineer against the specific project parameters.
Can a domestic extractor fan be used in a commercial kitchen?
Domestic extractor fans are not rated for the continuous duty cycles, grease-laden air, and elevated static pressures found in commercial kitchen environments. Commercial-grade fans such as those listed in this article are built for continuous extraction, higher airflow capacities, and the demands of professional kitchen operation.
How often should commercial kitchen extractor fans be serviced?
Commercial kitchen extractor fans should be inspected and serviced regularly as part of a planned maintenance programme, typically every three to six months depending on kitchen operating hours and cooking intensity. Regular servicing maintains airflow performance, reduces fire risk from grease accumulation, and extends equipment lifespan.
Do commercial kitchen extractor fans need to be speed-controllable?
Speed control is increasingly standard on commercial kitchen installations, both for energy efficiency compliance under Building Regulations Part L and for demand-controlled ventilation strategies that reduce running costs during lower-intensity service periods. All seven fans reviewed in this article include speed-control capability.
