Kitchens are often one of the most valued rooms in modern homes, and they are usually equipped with some sort of kitchen extractor fan that is installed above the stove or cooking surfaces to remove fumes. They not only serve a function, but they can also be decorative, and a lot of innovative design is being used in the manufacture, so that they can now be included as part of the decor in the kitchen. There is very little maintenance required with these fans, but understanding the operating principles, can help you make a suitable choice, as they are not all the same.
The kitchen extractor fan performs a very important function. Extracting vapours, and gases, made while cooking and safely expelling, so that they do not become obstacles or health risks is vital. The vapors may not only be hot, but they may also contain minute particles that can be harmful if large quantities are allowed to accumulate. Some kitchen extractors are designed, not only to remove particulates and vapours, but also to replace them with fresh air.
The kitchen extractor fan, or exhaust fan is usually mounted above the stove, and enclosed with an inverted funnel or bell-shaped canopy or hood that is connected to the duct work, so the fumes can be combusted or either expelled to the external environment. The range of shapes of available hoods have been now expanded to included classic circles and rectangles as they can be designed to add character and color and enhance the kitchen decor. The hood surface should be made of material that is easy to clean while being resistant to chemicals and heat.
There are different types of kitchen extractor fans, that are classified by the operating principles. Because vapors are lighter than air and move upward, updraft fans are the most popular, and very effective. They are also very easy to install. Downdraft fans are designed to force the vapors down, and some pressure must be applied to force the air downwards to vents that may be under the flooring, instead of in the ceiling. Non-vented fans do not remove the vapors, but circulate and diffuse them through the environment.
When choosing an extractor fan, the first consideration, may be your budget, in addition to the layout of the kitchen. Kitchen extractor fans, are installed with speed adjusters, and may be suitable for most homes. When space is limited, or there is no access to overhead ductwork, a downdraft fan may be a suitable option. You can also get professional advice from home improvement experts.
For proper functioning the hood must be at least as wide as the cooking surface. The manufacturer may also include some special tips and strategies in the installation instructions that should be read before any work is begun. The ductwork to the external wall, should be constructed in smooth metal, and should be in a straight a line as possible as less work is required to move the air through turns and corners.
