This experiment examines the "effect of indoor air conditioning electricity consumption." By ventilating the attic, the reduction rate of electricity consumption during air conditioning operation on sunny days was approximately 15% to 23% (*), confirming the energy-saving effect. Additionally, a comparison of temperatures between the attic, indoors, and the human body using a thermotracer showed that with a ventilation system, the temperature of wooden components such as beams in the attic and the ceiling surface was lower, and the temperature difference indoors was reduced with height. *Varies depending on conditions and the air conditioner's capacity and efficiency. Air conditioning operation time: 16:00 to 22:00 for 6 hours. 【Results of the indoor air conditioning electricity consumption effect experiment】 ■ The reduction rate of electricity consumption during air conditioning operation was approximately 15% to 23% (on sunny days). ■ The energy-saving effect was confirmed. *For more details, please refer to the PDF document or feel free to contact us.

For house manufacturers, the quality of housing is extremely important for gaining trust from customers. In particular, measures against moisture under the floor greatly affect the durability of the building and the living environment. If ventilation under the floor is insufficient, problems such as mold and condensation, corrosion of building materials, and pest infestations can occur, potentially shortening the lifespan of the building. These issues can lead to customer complaints and, in the worst case, the risk of legal liability. The underfloor ventilation system "Fuutaro" is a solution to prevent these problems in advance and improve the quality of housing. [Usage Scenarios] - Improving the quality of newly built houses - Improving the underfloor environment during renovations - Ventilation measures for high airtightness and high insulation houses [Effects of Implementation] - Improved durability of the building - Increased customer satisfaction - Reduced maintenance costs

The humidity indoors is visible as condensation, so by opening windows or using exhaust fans, the trapped moisture can be expelled outdoors. But did you know that there is also a lot of this moisture under the floor? Modern homes have achieved excellent comfort through high airtightness and high insulation. However, as the structural reinforcement of foundations has progressed, the crawl spaces have become lower and the compartments more complex, making ventilation under the floor more difficult. Just checking one of the items below does not mean you can relax. If any one of them applies, it is a danger signal for your home. 【Let’s check together】 ■ When you open the underfloor storage or tatami mats, there is a musty smell. ■ There are black stains on the walls near the closet or dresser. ■ There is always condensation dripping from the windows or the lower part of the window sills. ■ The tatami feels damp and spongy. ■ The floor creaks, or you occasionally see winged ants in places like the bathroom. ■ You often get bitten by mites. ■ The floorboards feel sticky. ■ The cloth foundation is always damp or has moss growing on it. ■ There are cracks in the cloth foundation. *For more details, please refer to the PDF document or feel free to contact us.

We conducted an experiment on how completely dried wood is affected by the ventilation conditions under the floor in a test house. Initially, the moisture content rises as it absorbs moisture from under the floor, but in the case of having a "subfloor ventilation fan" installed, the moisture content of the posts stabilizes at around 20%, as shown in the graph in the image. It can be seen that the moisture content is about 5% lower compared to when there is no "subfloor ventilation fan." 【Test Overview】 <Comparison of Moisture Content in Subfloor Posts in the Test House> ■ Duration: May 24, 2003 - July 27, 2003 ■ Post Size: 105×400mm, measuring 3 posts, the graph shows the average moisture content of the 3 posts ■ Measuring Equipment: Sanko Electronic Research Institute Co., Ltd.

Foundation insulation is a method of insulating the foundation that faces the outside air. The period when the risk of condensation and mold is highest with foundation insulation is from June to September of the first year after completion. The main cause is the large amount of water vapor coming from the concrete floor. Especially, wood that contains a lot of moisture significantly deteriorates in strength, so it is important to be cautious considering durability against earthquakes and typhoons. As a solution to these humidity problems, our company has developed a dedicated underfloor dehumidifier called "Dry Pro." It effectively eliminates humidity and condensation, and is useful for preventing mold, pests, and decay fungi in the underfloor wooden components. (Patent and design application pending) 【Features of Dry Pro】 ■ Dehumidification capacity of approximately 400-600cc per day on humid days during the rainy season and summer ■ Circulates dehumidified air widely using a blower ■ Quiet design: 45/44dB ■ Standard equipped with phytoncide that has deodorizing effects *For more details, please refer to the PDF materials or feel free to contact us.

"Dry Pro" is a floor underfloor dehumidifying fan that effectively eliminates moisture and condensation, and is effective against mold, pests, and decay fungi in the wooden parts under the floor. Assuming the early stages of new construction using foundation insulation methods, 36 liters of water were sprayed on the underfloor foundation of each building, and dried wood (cedar) was installed to measure the moisture content of the wood and the humidity under the floor. As a result, the buildings where this product was installed gradually dried out by repeatedly operating the dehumidification process every day, and after about two months, an average of approximately 70% RH dry condition was confirmed even outside of dehumidification operation hours. [Experiment] ■ Test House A - Floor area approximately 10 tsubo - Underfloor with foundation insulation method (Dry Pro installed) ■ Test House B - Floor area approximately 10 tsubo - Underfloor with foundation insulation method (without dehumidifying fan) *For more details, please refer to the PDF document or feel free to contact us.

- The following modes can be selected: A (exhaust) mode, A (exhaust) mode & B (mixing & diffusion) mode, timer mode, and stop mode. - When using the hybrid sensor, the operation is based on changes in water vapor content (measuring relative humidity and temperature to calculate absolute humidity) in timer mode. If the water vapor content is below the set value, it operates in A (exhaust) and B (mixing & diffusion) modes; if it is above the set value, it operates in B (mixing & diffusion) mode. * Moist air from outside is not allowed to enter under the floor. When "HB" is lit on the display, it indicates hybrid operation, and a special mode with phytoncide for efficient operation of the phytoncide effect can also be set. * A buzzer notification function has been added (during the 5/10 year inspection period or when the optional underfloor leak sensor or abnormal detection ventilation system is in operation). * If you desire a stronger effect (operation) from the exhaust fan during the summer or if there is a lot of moisture under the floor, please change the sensor sensitivity level setting to "H04," "H05," or "H00."
