Commercial Kitchen Extraction Systems
Extraction Systems
The engine behind every working canopy
Airflow calculated, not estimated
We calculate required airflow from your canopy’s capture area and cooking type, then select a fan and ductwork run to deliver it with an acceptable pressure drop. Get this wrong and you end up with a kitchen that’s too hot, a fan straining under load, or an extraction system that trips out mid-service.
Every system is also balanced against make-up air the replacement air coming back into the kitchen so extraction doesn’t pull doors shut, starve gas appliances of air, or drag cold draughts through the building.
- Airflow calculated from your canopy and cooking type
- Fan selected for noise, space and duty requirements
- Make-up air balanced to prevent negative pressure
- Controls and interlocks fitted as standard
System Components
What goes into a complete extraction system
Axial Fans
Compact, straightforward fans suited to shorter duct runs and lower-resistance systems, often used for smaller kitchens and takeaways.
Centrifugal Fans
Higher-pressure fans capable of handling longer ductwork runs and higher resistance, typical of larger commercial kitchens.
Roof-Mounted Fans
Positioned above roof level to keep noise and heat away from occupied spaces, and to simplify discharge point compliance.
Low-Noise Fan Sets
Selected where planning conditions, nearby residents or licensing restrictions limit the acceptable noise level from extraction plant.
Make-Up Air Systems
Supply air units that replace what's extracted, keeping the kitchen in balance and preventing doors, windows and gas appliances from being affected.
Controls & Interlocks
Standalone control panels or integration with an existing BMS, including fire suppression interlocks where a system is fitted.
Designed to satisfy planning and licensing conditions
Kitchen extraction fans are a common source of noise complaints and licensing conditions, particularly where a kitchen sits close to residential neighbours. We factor acoustic performance into the design from the outset fan selection, attenuator placement, and discharge point rather than treating noise as an afterthought once a complaint arrives.
- Acoustic attenuators sized to your noise limit
- Discharge point positioned to meet planning conditions
- Vibration isolation to reduce structure-borne noise
