About the "Automatic Stop Function after 10 Years" for the Underfloor and Attic Ventilation Fan Series.

Exhaust type + diffusion type unit! A subfloor ventilation series that detects humidity conditions and draws in dry air from beneath the floor.

The system detects the amount of water vapor (absolute humidity) and independently controls the exhaust ventilation system and the diffusion fan. When there is a high amount of water vapor, only the diffusion fan operates, and when it is low, the exhaust ventilation system also operates to bring in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and air supply with absolute humidity sensor POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor humidity, condensation, and mold ○ Powerful exhaust and diffusion For more details, please contact us or download the catalog.

24-hour ventilation (strong/weak, switchable) type

This product addresses the importance of ventilation highlighted by the Sick House Law. By specializing in underfloor ventilation, it responds to the negative pressure that occurs indoors due to ventilation fans (Type 3 ventilation system), which causes the indoor air to be depressurized, allowing air from under the floor to flow into the room. This characteristic prevents the inflow of dust, moisture, and other contaminants into the indoor environment that accompany the inflow of underfloor air during negative pressure conditions. Additionally, it simultaneously prevents the indoor inflow of harmful substances such as "formaldehyde." The dedicated controller detects the amount of water vapor in the outside air with sensors and automatically adjusts the ventilation system's operation strength, enhancing ventilation efficiency. 【Features】 - Effective against underfloor moisture, condensation, and mold - Powerful exhaust and mixing For more details, please contact us or download the catalog.

A comfortable indoor environment! Prevents condensation and extends the lifespan of the building.

The underfloor ventilation "Kazetaro" maintains a comfortable condition for wood by forcibly introducing air into the underfloor space. It is particularly effective in eliminating condensation. Underfloor ventilation also affects the indoor environment, reducing the conditions for the growth of dust mites and mold, which benefits the health of the family. The Kazetaro unit uses a hybrid sensor to detect the amount of water vapor (humidity) in the outside air, and the hybrid controller independently controls the Kazetaro blower type and Kazetaro mixer type, creating optimal ventilation operation for the wood under the floor. 【Features】 ○ Improves ventilation effectiveness to prevent pest breeding ○ Forcibly introduces air into the underfloor space to prevent condensation ○ Maintains a comfortable condition for wood, extending the lifespan of the building ○ Reduces the conditions for the growth of dust mites and mold, making the indoor environment comfortable For more details, please contact us or download the catalog.

Contributes to the prevention of condensation and mold under the floor. A new model compatible with the foundation packing method has been introduced.

The "DRY PRO" Ver3 is an electronic dehumidifying and blowing 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 construction, a new model "TYPE-C" compatible with foundation packing construction 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 parts under the floor. Furthermore, with the version upgrade in June 2024, a powerful dehumidification operation mode will be added. The surrounding temperature range for dehumidification operation (low-temperature dehumidification operation range) has been expanded, allowing operation at 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 fluorine-free 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 "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

It is possible to finish R-shaped parts that cannot be done with a centerless process seamlessly. This is ideal for streamlining and reducing labor in the finishing process. It is also possible to remove scale and perform finishing polishing using sanding belts or non-woven fabric buffs. By having robots handle the products, automation of mass-produced items is also possible.
