What is a fan in a ventilation system?<\/strong><\/b><\/h2>\n

We are living in a rapidly developing era with cities and apartments springing up like mushrooms, especially industrial factories and restaurants always operating at full capacity... Although this is convenient, it also makes our living space narrow and stuffy, as well as adding to the air pollution in the very room we live in every day.<\/p>\n

Ventilation fan<\/a><\/strong><\/b> is the most commonly used ventilation device in Vietnamese households. When operating, the fan will circulate air inside and outside the house, helping to remove stagnant air, mold, steam, heat from the house to the outside and bring fresh air from outside into the house. Normally, ventilation fans are used in places where air cannot circulate by itself.<\/p>\n
