Underfloor ventilation "Kazetaro"

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 will be under desorption conditions. By adding a ventilation fan to the subfloor where bamboo charcoal mats are installed, we have confirmed improvements in ventilation and airflow effects, leading to enhanced moisture absorption and release efficiency of the bamboo charcoal mats and reduced drying time. Furthermore, 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 the moisture content of the wood.

Regarding the "Automatic Stop Function after 10 Years" Automatic stop has been implemented in products manufactured from 2015 onwards. ■ Overview of Inspection Period Notification Function The dedicated controllers and timers for underfloor and attic ventilation fans sold since 2015 are equipped with the safety function mentioned on the left. Starting from November 2025, this automatic stop function will be activated sequentially for products manufactured in 2015. ■ Response Procedure at the Time of Automatic Stop It is anticipated that customers will contact the sales and installation stores. We ask that the sales and installation stores respond according to the following steps: 1. Conduct a safety inspection based on the "Underfloor and Attic Ventilation Fan Inspection Checklist." * Please be sure to check for looseness and retighten the connections of the controller and timer. If any liquids such as water, oil, or detergent have come into contact, the internal components may corrode, leading to ignition or fire, necessitating the replacement of the main unit. 2. If there are no issues, press and hold the set button to restart operation. ■ Start of Shipment for Controllers/Timers with Inspection Period Notification Function For details regarding the shipment history of timers, please contact our company: your sales representative or the Quality Control Department.

■Live Inspection Start Our company conducts inspections to provide our clients with a deeper understanding of the effectiveness, safety, and installation information of the products they sell. This includes visits to our simulation studio, experimental laboratory, test house, and production line. By observing the visualization of product effects, safety tests, and durability testing scenes, we have received feedback such as "I gained a deeper knowledge of the products" and "I can confidently propose to end users." We are pleased to announce the launch of our 'Remote Live Inspection Service,' focusing on smoke simulation and security systems, which are the main features of our inspections. Considering feedback such as "I am interested, but it's difficult to come all the way to Fukuoka" and "It's hard to coordinate schedules for multiple people," the content will be a condensed version, but we will ensure interactive communication similar to an in-person visit. 【Flow of Remote Inspection】 ■ For underfloor ventilation...

In homes where "flooding under the floor" has occurred due to heavy rain, various damages and risks of secondary damage are lurking in unseen areas. To protect the durability of the house and the health of the family, we have organized the points that should be prioritized for inspection and action. 【Table of Contents】 1. Why is inspecting under the floor essential? 2. 【Emergency Checkpoints】First, check here! A. Presence of flooding or moisture B. Condition of the wood C. Presence of unusual odors D. Signs of termites or pests E. Condition of ventilation openings 3. Immediate response methods upon discovering damage - Mild situations with little water pooling or moisture - - Situations with water pooling and concerns about structural impact - The damage from flooding under and above the floor due to heavy rain requires significant recovery efforts, including cleanup. We extend our heartfelt sympathies to all those affected. Please be sure to read the 【related materials】【related links】. ↓ ↓ ↓
