Ventilation in the garage with your own hands
Garage is a great way to protect your car from bad weather and hijackers. But the constant finding in the garage sometimes becomes disastrous for the "iron horse", and for health it is harmful to breathe gasoline vapors. Dirty musty air, increased humidity - all these "charms" of the enclosed area will soon lead to corrosion if the garage is not equipped with a ventilation system. For this reason, many car owners are wondering whether it is possible to make ventilation by their own hands. In this article, we will try to solve this problem.
Getting Started
First note that the garage can be with cellar or without .Air exchange technology is similar in all cases, but there are differences. For a garage with a cellar there can be three options for installing ventilation.
- The natural ventilation of the provides fresh air through a temperature difference between the outside and inside the room.
Mechanical ventilation is a system of expensive equipment that provides air inflow / exhaust.
Mechanical ventilation scheme
The combined ventilation system is essentially the same as natural, only the exhaust air is removed from the garage with special equipment.
The requirements of the
SNiP In the SNIP, the reference book of any self-respecting architect or builder, it is stated that fresh air in the garage should be delivered at a volume of 180 liters per hour. It is understood that the air will circulate constantly. Such are the realities in Russia, in Western countries the standards are more demanding - at least 360 liters per hour.
Materials, tools
For work we may need the following:
- perforator;
- sealant;
- Bulgarian;
- pipes, metal or plastic, Ø 10-20 cm;
- metal grilles;
- fans.
Ventilation in the garage with a basement
Let's start with a cheaper option - natural ventilation. It is easy enough to equip, in addition, it is ideal for a garage with a cellar.
Natural ventilation technology
Stage 1. First we calculate the ventilation based on the area of the garage. According to the requirements, 15 cm of air duct diameter is required for 10 m².Here is a small example. Let's say the size of our garage is 6 by 4 meters. It turns out that its area is 24 m².Then we proceed according to the formula:
2,4 x 15 = 36 cm
The result is that the diameter of ventilation ducts should be 36 cm, but only if there is only one extractor and one supply channel in the garage. If the hoods are two, then the resulting figure must be divided in two.
Stage 2 .We make holes in the walls, where pipes for air supply will be inserted later. They need to be done at a height of 10-15 cm from the floor. If the garage is brick or concrete, then we use a puncher.
4. In the holes we insert the pipes for the air intake
Stage 3 .When the air inlets are ready, we draw the hood. It will be on the opposite wall under the ceiling. Tools use the same. A pipe inserted into this hole will be removed above the roof. The larger its length, the more intensive will be the air exchange in the room. In general, the pipe should protrude at least 50 cm above the roof.
Installed pipes
Stage 4. Fill the emptiness of the void between the wall and the pipes. Particular attention is paid to the choice of sealant - it must provide a high-quality fastening of "miscellaneous" materials.
Also it is necessary to take care of the air duct equipment with protective grilles. This will ensure the security of your garage from the penetration of insects and rodents. In addition, above the exhaust pipe can be built a small dome, so that it does not fall atmospheric precipitation.
Protective dome for the
pipe This completes the work. As promised, installation of natural ventilation is a procedure, the cost of which will be about $ 50.

Technology of installation of combined ventilation
The combined type of ventilation, as already mentioned, largely resembles the natural one. Its design includes similar hoods and supply air ducts, the same pipes and openings( only the latter can be placed anywhere, not necessarily on opposite walls).Air will be removed by fans installed in the exhaust openings. Concerning the inflow, then, as before, it will occur naturally.
Buy only those fans that emit minimal noise during operation.
If you choose which of the two ventilation systems to install in the garage, then it is best, of course, to stay on the combined system. The cost of creating them is almost equal, the only difference is the cost of the fans.

Ventilation of observation pit
Inspection pit is a reliable assistant for every car owner. It should contain everything you need - keys, tools, storage tanks for oil and fuel, lighting and ventilation. All this is necessary for convenient and effective repair work.
There is enough natural ventilation for the inspection pit. If it works autonomously from the main system, then we do not need large pipes - it's enough for 10 cm in diameter. One of them is installed in the lower corner of the pit at an altitude of 10 cm from the floor, the second - in the opposite corner, but already 10 cm from the ceiling( this will be the hood and the second end of this pipe should take the air out).Protect the hood from getting debris, as described in the previous chapter.
And the last tip in conclusion: in winter, the pit and the cellar should be better closed, so that moisture and outside objects do not get into the room.
