To create forced ventilation in the bathroom, a fan is built into the air exchange system. It draws out the used air from the room, opening the way for a new portion of air to enter from neighboring rooms.
Sometimes, as an option to solve the issue of how to make a vent chinese overseas europe data a combined bathroom of a private house, something like a drain pipe with a recommended diameter of 110 mm is installed along the wall of the building, protruding above the roof level.
Axial fans are used in the ventilation of sanitary premises, the installation of which is carried out in a standard sequence:

The basement needs simple and effective ventilation, otherwise it will not meet the requirements imposed on it. For installation, 2 pipes with a cross-section of 80 to 150 mm, thermal insulation, protective canopies, gratings are needed.
The supply pipe is mounted with one end in the wall, stepping back from the floor by about 0.3 m. The top of the pipe, approximately 5.5 m long, should run along the outer wall. The draft is provided by the temperature difference in the upper and lower parts of the pipe.
Only a supply and exhaust ventilation system can handle ventilation of a large basement. Vertical air ducts are placed in the corners, an exhaust duct is placed under the ceiling, and a supply duct is placed at a certain height above the floor surface.
The top of the pipes is protected by canopies, which, in addition to their protective function, play an important role in regulating the speed of air passage.
The intensity of the draft also depends on the difference in the lengths of the supply and exhaust pipes. The greater this difference, the more powerful the flow. Normal ventilation should provide a 2-fold air change within 60 minutes.
