  • Whether ductwork, fans or lighting is required
  • Details of access into the building so that the number of sections in which the canopy is fabricated can be determined
  • The available headroom and ceiling height where appropriate is essential
  • The position of discharge to ensure that noise or odour does not create a nuisance
  • The amount of air to be handled by the canopy. This will also determine the type, size & number of filters and spigots required
  • Whether approval from the local authorities has been obtained – this is something that Dolphin Catering can assist with, especially with regards to the sound attenuation & odour control- we offer various methods of dealing with this, for example anti vibration mounts, silencers, carbon bag filters, ESP systems etc

Extraction hoods dimensions

The dimensions of commercial extraction hoods are invariably determined by the size of the catering equipment/appliances that it is serving.

Unless restricted by walls, the plan dimensions of the extraction hood always exceeds the plan dimensions of the catering equipment/appliances by a minimum of 300mm on each free side, and by 300mm at the front and rear.  The overhang dimensions are to the inside of the condensation or the supply plenum the appropriate dimensions shall be added when specifying the overall canopy size.

For combination steamers and certain types of baking ovens the overhang at the front will be increased to a minimum of 600mm to cope with the steam or fumes released when the doors of the appliances are opened.

The height of the extraction hood is usually determined primarily by the ceiling height.  The underside of the canopy should be located between 2000 & 2100mm above the finished floor level, the top should project into the ceiling by a minimum of 25mm to allow the false ceiling trim to be fitted.

With kitchens that have high ceilings, consideration should be given to providing infill sections to fill the gap between the top of the canopy and the underside of the ceiling.

Extraction hoods lighting

Lighting in a kitchen canopy should provide an average illumination level of approximately 500 lux at the working surface and standard fluorescent type fittings installed at a height of 1200mm above the cooking surface should fulfil this requirement.  We offer low profile lights to 500 lux

The lighting housing is recessed into the canopy to provide easily cleanable surface.  Where surface mounted lights are unavoidable then smooth surfaces are ensured for good clean down accessibility.

The lighting housing is easily removable for easy access to clean and the replacement of tubes when necessary.

Commercial Kitchen Extraction Hoods FAQs

Are commercial kitchen extractor fans a legal requirement?

According to the Workplace (Health, Safety and Welfare) Regulations 1992, it is the duty of employers to ensure that all enclosed workplaces, including kitchens, are equipped with effective and appropriate ventilation systems.

What is the difference between a cooker hood and an extractor?

When it comes to cooker hoods, there are two distinct categories with a significant difference in their functionality. Extraction hoods function by drawing the air from your cooking area and venting it outside, while recirculation hoods filter the air and circulate it back into your kitchen.

Is it ok to have a fan in a commercial kitchen?

In commercial kitchens, extractor fans play a crucial role in ensuring a safe and comfortable environment for both staff and customers. These fans effectively reduce the build-up of grease, smoke, and heat, which can otherwise pose significant health and safety risks.
