Fans are selected depending on the type of design:

Air is supplied to the room by taking two boards from the floor. The outflow occurs due to the lack of one board. The pit should be located strictly longitudinally and inside the garage. One edge is placed near the supply entrances to the boxes, and the other - near the exhaust duct. Open flooring boards allow the supply air to partially enter the pit. The opposite edge serves as an outlet for accumulated moisture.
The inflow will be provided by installing an air vent pipe. It is used to collect incoming air for ventilation. The air duct of the adjacent dump acts as an exhaust. The inflow channel should be located at the edge of the inspection pit.
The holes in the garage let incoming fresh air and pass it through the pipe in parts. Then the rest of the air ends up in the pit. Since it is located next to the cellar and is in contact with the air duct, it is easy for the flow to follow after entering the pit exhaust to the outside.

The supply pipe has a fan. The exhaust opening is mounted by a mechanism in a forced manner using fasteners. The ventilation of the space operates automatically.

Equipment and materials
The necessary tools for installing ventilation in the garage are a grinder and a hammer drill. After making calculations, buy plastic or metal pipes. They need a sealant and fans. To secure the ventilation inlets/outlets, it is worth buying covers and grates.

The hammer drill must be powerful, otherwise it will not be possible to make a recess in the wall or it will be uneven. It is advisable to have an angle grinder and heat-insulating material at hand.

Exhaust duct devices. Available, easy to use. Built-in regulators allow you to change the intensity and speed of the air flow. The optimal diameter is about 160 mm. To save money, it is easier to buy 120 mm.
Centrifugal. Difficult to install, but ideal for exhaust. It is better to use them in garages where chemicals and paints and varnishes are used.
Vortex. Suitable for rooms where welding work is regularly carried out.
If the garage is intended only for storing a vehicle and does not involve any work in it, then you can choose the most practical and popular option - an exhaust duct fan. This is the cheapest design, and less complicated to operate.

For the construction of air ducts, it is better to use asbestos or galvanized pipes. A through pipe can be installed using a through method, when the ventilation pipe is carried through the garage floor and brought out through the roof, and a wall method, when the exhaust pipe is sealed into the cellar wall and brought out beyond the boundaries of the building.
