Extraction Fans
Extraction fans drive the airflow through a commercial kitchen’s canopy and ducting system, pulling grease-laden air out of the building and, in balanced systems, pushing fresh make-up air back in. They suit pubs, restaurants and dark kitchens as the powered heart of any extraction setup, and fan power (kW) and airflow capacity are matched to the canopy’s extraction rate rather than buying on price alone. The category also takes in fan-in-box units, fume filtration units and single- and three-phase fan speed controllers.
Key specifications
Commercial extract fans typically range from around 0.25kW for small units up to 3kW+ for high-volume cookline extraction, built in weatherproof housings for external or rooftop mounting, with extraction rates matched to ducting from 150mm to 500mm diameter.
Extraction Fans — FAQs
What size extraction fan do I need for my kitchen canopy?
Fan capacity (m³/h) should match or slightly exceed the canopy’s rated extraction rate, accounting for ducting length and number of bends, which each add resistance and reduce effective airflow.
Centrifugal or axial fans for commercial kitchen extraction?
Centrifugal fans are the standard choice for grease-extract systems because they handle higher static pressure from long ducting runs; axial fans suit shorter, more direct extract runs with less resistance.
How much power (kW) does a commercial extraction fan use?
Typical commercial kitchen extract fans run from around 0.25kW for compact café setups to 2-3kW for full cookline systems, with running costs depending on hours of use and local electricity rates.
