Description
↓↓
A ventilation fan is a device used to remove stale air, smoke, heat, or moisture from a room.
It improves air quality by circulating fresh air and reducing indoor pollutants.
Ventilation fans are commonly installed in kitchens, bathrooms, and industrial settings.
They can be wall-mounted, ceiling-mounted, or duct-connected, depending on the space.
These fans help prevent mold, odors, and heat buildup in enclosed areas.
History
↓↓
The concept of mechanical ventilation dates back to the 19th century during the Industrial Revolution.
Early ventilation systems were used in factories and mines to ensure worker safety.
The modern electric exhaust fan became common in homes in the early 20th century.
In Japan, ventilation fans became widespread during the postwar housing boom.
Technological advances led to quieter, energy-efficient, and automatic models.
Today, smart ventilation systems can adjust airflow based on humidity or air quality.
They play a crucial role in maintaining healthy indoor environments in modern buildings.
