Regardless of in what house you live: multy-storey, low or private, at their design by architects the ventilation system providing free air circulation in all rooms was provided. Usually in those from them where there are no foreign smells and the increased humidity, rather natural aeration through window leaves and open windows, but for bathrooms, bathrooms and kitchens the compulsory ventilation system has to be used.
In multifamily houses as compulsory ventilation system adits of air ducts which provide intake of fresh air to apartments are used. But if they are killed, owners of apartments should think of installation of exhaust fans to bathrooms and kitchens.
In bathrooms they are necessary that condensate did not accumulate indoors and there was no fungus and mold. And in kitchens the forced-draft ventilation is necessary for removal of the fireproof remains which are allocated in the course of work of gas-fires and also the child and smoke from fats and oil which are formed when frying products in the mode of high temperatures. The cancerogenic substances emitted in air have unpleasant smell and, in addition, are very noxious to health. Therefore it is important that the polluted air quickly was substituted fresh, arriving from the street, and for this purpose it is possible to use extract or cheaper option – the exhaust fan.
If in bathroom or the bathroom the fans can be connected so that they began to work along with light inclusion, such scheme does not suit for premises of kitchen. Practice shows that the most convenient option in this case is installation of the fan working with the timer of time on which the necessary time of airing is determined. The simplest option – inclusion and switching off of the fan in the manual mode is more often used.
It is possible to automate operation of the kitchen fan, having installed additional devices: controller of humidity or sensor of presence.
As for installation site, it is for this purpose better to choose point under ceiling where warm air from plate rises. To delete it quickly, the fan has to be located over plate or in close proximity to it. Judging by responses of the users published at forums on the Internet many just install such fans directly in window frames.
When choosing the fan, pay attention to its power. For small kitchen which area does not exceed 6 sq.m. the fan with power up to 180 cubic meters an hour, will be suitable for 10 meter kitchens – up to 300 cubic meters an hour.
Do not forget that this device worked as much as possible effectively, it is regularly necessary to clean ventilatory blades and available parts of the mechanism from soot and fat.
