Effects of using a moisture-absorbing agent (bamboo charcoal) in combination with an underfloor ventilation fan.

セイホープロダクツ業務本部

We highly recommend that customers who have already installed moisture control materials (such as bamboo charcoal) consider adding a subfloor ventilation fan. We will compare and verify the moisture control effects/performance of using only subfloor moisture control agents (bamboo charcoal) versus using both subfloor moisture control agents and mechanical ventilation through moisture absorption and desorption tests. *The operation time of the ventilation fan is under desorption conditions. By adding a ventilation fan to the subfloor where bamboo charcoal mats are installed, we confirmed improvements in ventilation and airflow effects, leading to enhanced moisture absorption and release efficiency of the bamboo charcoal mats and reduced drying time. Additionally, it is expected that the combined use of the ventilation fan will further improve moisture control performance, leading to a decrease in subfloor humidity and enhanced drying effects on wood moisture content.
