Kitchen exhaust is a device designed to purify the air of odors, fumes, smoke and other impurities that are formed during the heat treatment of products.
There are two main types of devices.Circulating kitchen hood allows you to clean the air by means of filters and return it back to the room. In such devices, carbon filters are usually used to absorb odors, and grease, soot and fine droplets of fat. The latter variety is made from synthon or non-woven fabric and needs periodic replacement.
More convenient is metalreusable cassette type filter. This consuming device must be removed from the device periodically and washed with soapy water. In many models of devices, two or three grease filters are used.
The coal cleaner should be replaced depending on the intensity with which the cooker hood will be used.
Flowing cooking hood can removesoot and evaporation through the ventilation system of the building. It is more difficult to install, because it requires installation of chimneys, which are connected to the ventilation hole. However, the kitchen hood is highly efficient. It allows you to throw out polluted air, and, thanks to the creation of a differential pressure, ensure the supply of fresh air.
Flow devices in their design haveOnly the grease filter, which prevents accumulation of fat on the blades and walls of the duct. There are inexpensive models in which filters are generally absent. Such a kitchen hood requires more thorough care.
When choosing a device, you need to look at thedimensions and design of the device. However, the main indicator is the capacity of the device. This depends on the volume of air permeated per unit time. The efficiency of the device is affected by the power of the fan motor, which varies from 150 to 750 cubic meters per hour for different manufacturers. For an ordinary standard kitchen, stretching is sufficient with a capacity of 300-350 meters cubic.
When purchasing a device, it is necessary to take into account the parametersnoise. Although modern devices have this indicator is normal. The kitchen hood works practically without any extraneous sounds, thanks to the use of special bearings and acoustic bags.
Many air cleaners have a setadditional functions. Since the kitchen hood is mounted with its own hands above the stove, it can also be used for lighting. In modern appliances are installed lamps of different power, which make the process of cooking more convenient and more pleasant.
