Ventilation in the kitchen: DIY hidden ventilation ducts

The importance of air exchange at home is especially felt in the food preparation area. If the air saturated with fats, moisture and odors is not removed in a timely manner, all these components will penetrate into living rooms and settle on the walls. For a kitchen hood, it is necessary to arrange a separate ventilation duct with forced injection.

The first thing to do is to identify the location of the channels, the point of connection to the common channel and the point of air intake. Then mark the wall for a vertical channel with an intake socket. In our case, plastic ventilation ducts with a cross section of 75×150 mm will be used.

Please note that the pipe joints are additionally covered with tape for better tightness..

Be sure to check the draft – it should be present even without a fan. If there is no draft or an inflow is detected, it is necessary to eliminate these problems in the ventilation system (revise it).
