Ducted or Recirculating
Domestic cooker hoods are an essential kitchen appliance as they ensure that odours and steam are extracted from the cooking area. Cooker hoods can be split into two basic extraction categories: ducted mode or recirculating mode. Ducted cooked hoods are generally the most popular method of kitchen extraction in the UK, however recirculating hoods are more versatile as they can be installed in any kitchen scenario with little effort required.
Ducted Cooker Hoods
Ducted cooker hoods are the most effective at extracting cooking fumes, odours and steam as the air is drawn directly outside. Grease and fat is captured on the stainless steel filters and cooking air is expelled through ducting to the outside of the property.
- Effectively removes cooking odours, smoke and other airborne contaminants from the building
- Using 150mm wide solid ducting for your hood ensures the quietest noise output during use
- There is no need to regularly replace charcoal filters which can help to keep running costs to a minimum
Recirculating Cooker Hoods
Recirculating cooker hoods filter the fumes and steam from the air and then recycle the cleaned air back into the kitchen. Recirculating cooker hoods need additional charcoal filters in order to cleanse the air effectively – charcoal filters work to absorb the grease and condensation that would be expelled through external ducting.
Many of Faber’s cooker hoods have the option of being used in either ducted or recirculation mode, with optional chimney kits supplied with most hoods.
- Recirculating cooker hoods can be installed in any location as there is no ducting outlets to be planned in advance
- Recycling cleaned air back into the home means that warm air and smoke is not pumped back out into the environment thus making recirculating hoods an eco-friendly option.
- You may be able to install your recirculating hood without the use of a chimney.
What extraction rate do you need?
Often overlooked, there is a simple formula that helps you to work out the minimum extraction rate needed to effectively clean the air in your kitchen. This is determined by the volume of your kitchen and the concept that a cooker hood working correctly changes the air approximately 10 times an hour.
EFFECTIVENESS = Kitchen m² x Kitchen height x 10 changes of air
E.g. If your kitchen is 5 metres long by 3 metres wide, you have a 15m² space. Multiply the 15m² by the height of the room, in this instance 3m tall and then multiply by 10 to reflect the expected changes in air. 15m²2 x 3m x 10 = 450m³h.
Once you have the minimum extraction rate needed for your kitchen space, you can check the performance tables for Faber hoods to find a cooker hood that will meet the demands of your space. It is important to find a hood that will work effectively on the lowest settings as this reflects normal everyday use.
The noise level that a hood produces when a hood is in use is an important factor to consider when choosing a cooker hood. A powerful motor makes a quieter hood, as the hood is effective on the lowest levels.
Many Faber hoods operate at decibels of 60 or less, which is around the sound levels of a normal conversation. Faber have a number of technological benefits that work towards reducing the sound output from cooker hoods:
The perimeter extraction panel reduces the perceived sound by 25% (which is equal to a reduction of 3dB).
The optional remote blower kit allows the hood motor to be removed from the hood and installed elsewhere within the home to reduce the sound output in the cooking area. Consider installing a remote blower kit in a utility room or garage.
Specially developed by Faber, Sil-K Act reduces the hood sound output by 13dBs using noise cancelling technology.
Faber’s ENERGY motor reduces noise output by up to 3dB (A) and increases hood efficiency by 30% even in the presence of long ducting.
