If you do not want to smell and steam from the kitchen spread throughout the apartment, then you should install the hood . But in order to really get rid of these effects of cooking, you need to choose it correctly.
There are two main types of kitchen hoods - circulating (filtering) and evacuation (retracting). For home use, the second type is better suited, since they provide the outlet of polluted air to the street, thanks to this principle of work they are considered more productive and not so expensive, as there is nothing to change, it is enough to wash it in a timely manner.
Choosing a retractable kitchen hood, you will definitely need to select an air duct for it, because it depends on it the throughput of the device. To make it easier to determine which one you need an air duct, we'll look at the main types of the airway in this article, and what parameters should be taken into account.
How to choose an air duct?
The most important thing that you need to pay attention to when buying an air duct for a kitchen hood is its diameter and the material from which it is made. There are models with different diameters (125 mm, 150 mm, 160 mm, 200 mm, 210 mm, etc.) of which it is very easy to choose the most suitable for you.
Since the duct must fully cover the hole on the hood, their diameters must match, or the pipe size should be slightly larger. If this is not the case, then the efficiency will drop dramatically, as dirty air will still flow back to the kitchen.
Ducts for kitchen hoods are:
- Plastic (PVC, polyethylene, fiberglass);
- aluminum;
- steel.
Made of metal structures are highly durable, but they are quite heavy and expensive. Plastic, however, is light enough, and easy to connect parts. Of PVC and aluminum, corrugated pipes are more often produced, which are very popular due to the ease of installation and the ability to give them any shape in different directions, but they are not very robust. Therefore, it is up to you to decide which material to choose the duct to the kitchen.
Not only round there are air ducts for kitchen hoods, but also rectangular or flat. They look more aesthetically and so they do not have to be hidden, but it's much more difficult to give them the right shape.
