In preparation time of various dishes the apartment is filled by strong smells which not always stimulate appetite, and opposite, can cause irritation. Besides, on kitchen furniture the greasy raid appears over time. For fight against these troubles in kitchen establish extract. Choosing this device, it is important to pay attention to technical characteristics and compliance to number of the parameters playing crucial role when mounting extract.
Design of extract
Extracts which consist of four main components: the fan unit, the air intake, filters and the body, externally differ from each other. The simplest – flat devices. They happen two types: built in and hinged. The last fasten on wall or the bottom of locker over plate. The built-in units are mounted in hinged kitchen cabinet therefore before purchase it is necessary to make sure that certain model will enter locker and that in it it will be possible to prepare the corresponding opening.
Also chimney extracts which name goes back to form of devices are most widespread today. They are mounted on wall over plate. These models are more productive, most of them are capable to work in the mode of branch and recirculation of air. Island extracts which fasten to ceiling over kitchen "island", and the angular devices intended for fastening in corner of kitchen have already entered the range of many firms.
For dressing of extracts use tempered glass, the tree covered with protective varnish, artificial stone and metal elements painted manually.
Materials
The extracts made of stainless steel and aluminum are most popular. Models from the polished stainless steel look quite effectively. Such surface easily washes, however it cannot be cleaned abrasives. Lack of this material is that on it there are traces of fingers, and producers recommend to look after such products by means of special structures. Aluminum units are good the fact that their surface "adapts" to color of kitchen objects, successfully fitting into interior. Besides, on aluminum extracts there is no trace of fingers left.
Principle of work
Choosing extract, it is necessary to decide for himself as it will delete unpleasant smells – by means of branch or recirculation of air. Both options have the advantages and shortcomings. The majority of modern devices is arranged in such a way that can work in both modes, however if the air duct is not laid, the device can be operated only in the recirculation mode. At recirculation the fan tightens air under umbrella and, passing it via filters, returns back in kitchen already clean. Hostesses praise such extracts for the low price and simplicity of mounting, but often remain are dissatisfied with the low performance and need to periodically change charcoal filter.
For the correct functioning of extract take care of that the air ducts acquired in shop have been correctly mounted.
In the branch mode air also gets the fan and is passed via the zhiroulavlivayushchy filter, however does not come back, and is thrown out the air shaft or on the street on the special channel. This method of fight against smells is more effective, but mounting of air duct is rather labor-consuming. It has to be well sealed and have the special valve interfering penetration of cold air from the street to the room at the exit.
