COOKER HOODS
These are special types of fans that are fitted in the kitchen and get rid of grease,steam and smells from the kitchen
These come as two basic types or designs
a.recirculating-which is filtered through carbon filters that capture the grease and odours inside the charcoal peices
b.ductet,which take the air out directly through a hole in the wall.
THE WORKINGS
Air is drawn through a grille at the bottom of the extractor fan through grilles with a grease filter mesh on the underside
The air is then drawn into the carbon filters ,recirculated then re-juvenated back as clean air.
Ducted vents take the air out directly so therefore speeding up the process of re circulating the air.
Most extractors come with a speed switch to regulate the speed of circulation.
Another useful constant is a light which is used to illuminate the cooking area
MAINTENANCE
To refrain excessive build up of grease,the extractable hood needs to be washed in warm soapy water,and if it is doable to
wash the mesh then do the same.
The carbon filters will also need to be changed from time to time depending on the amount of use and the colour change of
the filters.
TROUBLESHOOTING
