We will introduce the operation program of the "Fuutarou Unit." The hybrid sensor detects the water vapor (humidity) in the outside air, and the hybrid controller independently controls the Fuutarou blower type and the Fuutarou mixer type. It operates ventilation to create a suitable environment for the wood under the floor. 【Features】 ■ Prevents pest breeding - By improving ventilation, it reduces the conditions for pest breeding. ■ Prevents condensation and extends the lifespan of the building - By forcibly bringing in air, it maintains a comfortable state for the wood. - Particularly effective in eliminating condensation. ■ Creates a comfortable indoor environment - Reduces conditions for the growth of dust mites and mold, contributing to family health. *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.

The "Kaze no Suke Blower 24" is a system that continuously ventilates the attic for 24 hours, preventing the inflow of chemicals into the indoor space by lowering the air pressure compared to the forced-ventilated interior, thereby creating a safe living environment. It detects the temperature in the attic with a temperature sensor and allows for variable operation. It also features a condensation mode that is effective in removing condensation. Additionally, it has obtained patents and design registrations, and has won a Good Design Award! 【Features】 ■ Discharges hot air and improves cooling efficiency Helps reduce excessive use of air conditioning, benefiting family health and saving on electricity bills. ■ Shuts out condensation By actively moving the air in the attic and minimizing temperature differences, it eliminates the causes of condensation, prolonging the lifespan of the house. ■ Supports the health of families and homes With high ventilation capacity, it effectively expels formaldehyde and VOCs from the attic to the outdoors. *For more details, please refer to the PDF document or feel free to contact us.

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 "DRY PRO" Ver3 is an electronic dehumidifying and ventilation unit for underfloor use, combining a Peltier cooling device with a dedicated stirring and diffusion-type blower. In addition to the diffusion-type model "TYPE-D" for foundation insulation methods, a new model "TYPE-C" compatible with foundation packing methods has been added to the lineup. It can dehumidify even in areas where moisture tends to accumulate by stirring a wide range of air. It helps suppress moisture and condensation under the floor, contributing to the prevention of mold, pests, and decay fungi in wooden components. Furthermore, with the version upgrade in June 2024, a powerful dehumidification operation mode has been added. The surrounding temperature range for dehumidification operation (low-temperature dehumidification operation range) has been expanded, now accommodating surrounding temperatures down to 5°C. 【Features】 ■ Easy installation with a φ22 drainage hole (no drainage pump required) ■ Automatic operation possible with a dedicated indoor controller ■ The direction of the aluminum duct of the blower can be set freely ■ Dehumidification capacity of 1800mL per day (depending on conditions) ■ Uses non-fluorinated electronic cooling technology ■ Compatible with underfloor flooding sensors (optional) *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."
