If a house, building or office area is completely sealed then you can get fresh air only when you open a door or window. We need proper ventilation to exhaust unwanted smells, water vapor, and pollution, and also replace them with fresh air.
Ventilation is mainly of two types – natural ventilation with the help of windows and mechanical ventilation with the help of fans, blowers, etc. If you want to know more about ventilation equipment, you can consider http://www.sapa3online.com.
Fans are used to provide fresh air in the houses or factories but they are also helpful in some areas where there are unusually high temperatures. We can not use desk fans or stand fans everywhere in the building. That is why ceiling fans are used where needed.

These days, fans have some additional functions also. They don’t only ventilate the room but have other features like lighting the room. With modern design and technologies, you can perform both the tasks of lighting and room ventilation.
Ventilation plays an important role in industries. In the industries, there are various harmful vapors, toxic airborne particles, and much more. Ventilation provides better temperature, removes harmful particles, and reduces the risk of fire in the industries.
The health problems caused by polluted air can be avoided with the installation of a good ventilation system. So, we can say that ventilation is necessary for the industries and our residential areas so that we can breathe in the fresh air.
