Cooker hoods are becoming a standard fitting in many new and refurbished kitchens and are certainly a boon in alleviating cooking smells and the reduction of steam from boiling pans.
Extraction is achieved by means of a motor, usually a shaded-pole type, which drives a normal or barrel fan. Variable speeds are often included for coping with different conditions, and a light to illuminate the hob, independently switched, is another helpful addition. Read the rest of this entry »

When the hood is switched on, the fan sucks air through a filter system to remove grease particles and cooking smells. Read the rest of this entry »
