What is an underfloor ventilation fan?

An underfloor ventilation fan is a part of the ventilation system installed under the floor of a building. In general, air tends to stagnate under the floors of houses and buildings, which can lead to high humidity. This is because there are no ventilation holes under the floor or poor ventilation. Underfloor ventilation fans are installed to solve these problems and improve conditions under the floor.

Advantages of underfloor ventilation fans

01.

Humidity control/ventilation improvement

Underfloor ventilation fans help keep the humidity below the floor within a suitable range. In high humidity environments, there is a risk of mold, rot, and termite damage to the wood beneath the floors and the building's foundation, but using ventilation fans can help regulate humidity and reduce these problems.

03.

Preservative effect

High humidity and improper ventilation conditions can cause structural materials (such as wood and foundations) beneath the floor to deteriorate and rot. Underfloor ventilation fans can help prevent these damages and extend the lifespan of your building.

02.

Maintaining building health

The installation of ventilation fans improves ventilation under the floor and maintains the health of the building.

04.

Mold prevention

Mold growth is more common in high humidity environments. Proper humidity control provided by underfloor ventilation fans prevents mold growth and improves indoor air quality.
