This type of ventilation is suitable for many due to its ease of installation and low cost. It is also commonly us for cellars.
Installation of ventilation in a garage Installation of natural air begins with calculations.
According to SNiP, for every 10 square car owner data area there should be 15 centimeters of air duct diameter.
For example, the size of the garage is 5 by 4 meters. The area of the garage will be equal to twenty square meters. We calculate according to the formula: 20 * 1.5 = 30 centimeters.
As a result, we get a channel diameter of 30 centimeters. If you plan to install two exhaust hoods and two supply channels, you should ruce this value by half.
The picture shows the ventilation in the garage david robinson attorney at law your own hands, the diagram shows the location of the ventilation openings.

The next stage is preparing an opening for air intake. It is made using a hammer drill at a height of about ten centimeters from the floor. Proper Installation of natural air of the garage will occur when installing an exhaust hood in the opposite italy numbers wall, and it is desirable that the opening be made diagonally.
Using a hammer drill, we do the same thing, only under the ceiling. This is necessary because the ventilation pipe will be brought out above the roof of the room to a height of about fifty centimeters.
Height of the pipe above the roof
Next, treat the voids between the wall and the pipe with a sealant. For better bonding, you ne to choose a sealant that allows you to connect different materials.
At the very end of the installation, you ne to take care of the equipment of protective devices. To prevent rodents and insects from getting into your garage, protective grilles are install. A small cover or dome will help against precipitation.
Thus, the installation of ventilation will cost about 300 rubles. It is worth considering that natural air exchange is most effective at an outside temperature of less than 10-12 degrees Celsius.
Accordingly, in summer, air exchange will be ineffective. In addition, pipes often freeze in winter, which leads to overcooling of the room.
Installation of a combin circuit
This scheme is practically no different from the previous one. In the same way, a hole will be made on one side of the garage at a height of ten centimeters Installation of natural air floor. The only difference is that there is no ne to make an exhaust hole in the opposite wall. Installing a fan allows you to do it anywhere.In the combin scheme we add an exhaust fan
Thus, the combin method of air exchange is more suitable, as it will work effectively at any time of the year.
As for fans, many of them have minimal power consumption, so when buying, you should choose the one that will produce the least amount of noise.
Mechanical air exchange
Forc ventilation in the garage is achiev by installing fans in the air inlet and outlet openings. However, there are other devices that can cope with this task.
Let us list just a few of them:
- Heating bulb. It is install in the pipe itself. It Installation of natural air the air, and as a result, the pressure increases;
- Weather vane-diffuser. Attach to a pipe that performs the supply function. Works due to wind pressure;
- Deflector. Unlike the weather vane-diffuser, it is install on the hood. Better exchange is ensur by diluting the air;
- Monoblock. Among exhaust specialists, it is consider the best option for providing ventilation in a garage. Thanks to this system, the owner has the ability to control the entire air exchange process. Air exchange done in this way will be the most effective compar to natural and combin. The only downside is the cost of installation, which can reach 240 thousand rubles or more.
However, in some cases, forc ventilation in the garage with your own hands can be quite inexpensive. To do this, you ne to do the same as for installing natural ventilation: use a hammer drill to make holes in opposite walls diagonally and install pipes in them. Then install a fan on the inlet openings of the air ducts.
This scheme will allow you to regulate air Installation of natural air at any time of the year. In order to prevent the air duct and the garage box itself from freezing in winter, you can install valves or fan spe controllers. And to protect the room from moisture in winter, experts advise closing the inspection pit or cellar.
Air purification in the cellar
As a rule, a garage is us not only for parking a car, but also for storing food. Accordingly, this also provides additional moisture. But even if storage is not carri out, ventilation of the pit should be organiz for comfortable work in it.
Combining cellar and garage ventilation
As experts note, natural ventilation is the best option in a cellar.
Provid there is good air exchange in the room, it is possible to use pipes with a diameter of 10 centimeters.
One of them is install about ten centimeters from the floor, and the second one is on the opposite side, ten centimeters from the ceiling. The end of the upper pipe is brought out.
