The "Airful(R) SK TYPE" is a whole-house 24-hour ventilation heating and cooling system that creates an indoor environment without temperature differences, similar to spring or autumn, no matter where you are. This system ventilates the crawl space and attic with an external insulation design. Pollen brought indoors and house dust generated inside are filtered through a total heat exchanger to produce clean air. By adjusting the air temperature and distributing it through ducts to each room and common areas, it eliminates temperature differences between rooms, allowing for comfortable living at a consistent temperature throughout the house. The ducts use a patented (Patent No. 5108451) urethane-formed duct that has low pressure loss and excellent insulation performance. Even in cold winters, it maintains a constant indoor temperature, preventing accidents caused by heat shock. Additionally, it allows for ventilation, enabling a comfortable environment while preventing infections caused by viruses. 【Features】 - Refreshing - No temperature differences anywhere - External insulation design - Ventilation of crawl space and attic - Produces clean air *For more details, please request materials or view the PDF data available for download.

We recommend the introduction of the whole-house 24-hour ventilation heating and cooling system "Airful" to address condensation, house dust, and heat shock issues in high airtight homes. High airtight homes, which are designed to prevent drafts, maintain a good air environment by combining planned ventilation. Ventilation systems typically operate in a way that minimizes heat loss while exchanging necessary air. They are not suitable for exchanging large volumes of air at once, and if heating equipment is added later, it may lead to inadequate ventilation and worsen air circulation. Therefore, when building a high airtight home, it is essential to include the ventilation system in the initial planning. 【Features of Airful】 ■ Removes pollen, house dust, and cigarette odors ■ Eliminates discomfort caused by temperature differences *For more details, please refer to the PDF materials or feel free to contact us.

Did you know that "house dust" contains various substances? While it is difficult to eliminate all sources of it, it is possible to reduce house dust inside the home. At our company in Gunma Prefecture, we recommend the introduction of the whole-house 24-hour ventilation system "Airful" as a measure against house dust. By passing air through a heat exchanger, we can create clean air, which helps to suppress pollen brought in from outside and house dust generated indoors. 【Features of Airful】 - Removes pollen, house dust, and cigarette odors - Eliminates discomfort caused by temperature differences *For more details, please refer to the PDF materials or feel free to contact us.

Currently, homes have become highly airtight, but are you aware that this actually leads to insufficient ventilation? When the concentration of carbon dioxide indoors rises due to inadequate ventilation, it can result in decreased concentration and decision-making ability, as well as symptoms like headaches and shortness of breath. For those who find it difficult to ventilate regularly due to the location of their home or lifestyle, utilizing ventilation systems or whole-house air conditioning can help resolve the issue of insufficient ventilation. These systems not only facilitate natural air exchange but also help maintain temperature and humidity, making it less likely for condensation to occur. Therefore, if regular ventilation is challenging for you, please consider this option. [To resolve insufficient ventilation] - Open windows - Clean ventilation fans and ducts - Utilize ventilation systems and whole-house air conditioning *For more details, please refer to the PDF document or feel free to contact us.

Our entire building's 24-hour ventilation and heating/cooling system "Airful" is a recommended ventilation system for high-insulation, high airtightness homes. A high airtight home refers to a residence that has minimized gaps in ceilings, walls, and fixtures, thereby enhancing airtightness compared to traditional homes. Unlike older wooden houses, modern homes have high airtightness due to the widespread use of aluminum sashes, making them less susceptible to outside influences. Additionally, many of these homes are also highly insulated, which is why they are often referred to as "high airtight, high insulation homes." **Benefits of High Airtight Homes:** - Improved heating and cooling efficiency, leading to energy savings - Contributes to the health of the family - Reduces concern about outside noise and noise within the home - Increases the efficiency of the 24-hour ventilation system *For more details, please refer to the PDF materials or feel free to contact us.*

At our company in Gunma, we provide a 24-hour ventilation heating and cooling system called "Airfull" that creates a comfortable environment throughout the year. Ventilation involves bringing outside air indoors to replace the air, but what exactly is a "ventilation system"? Let me briefly introduce it. A ventilation system is a system that uses ventilation equipment to forcibly replace the air without opening windows. To prevent sick house syndrome, it is mandated by the Building Standards Act that homes built after 2003 must have a ventilation system installed. [Types of Ventilation Systems] ■ Type 1 Ventilation ■ Type 2 Ventilation ■ Type 3 Ventilation *For more details, please refer to the PDF materials or feel free to contact us.

In daily life, more than ten times the amount of air compared to food and water enters our bodies. The majority of the air we inhale comes from our homes. The quality of air is not determined solely by the amount of pollutants. In addition to the "purity" of the air, the balance of four elements—"temperature," "humidity," and "airflow"—is crucial in determining air quality. If any of these elements become unbalanced, various pollutants can accumulate in the air, negatively impacting the health of your family. To prevent such situations, we recommend the introduction of the whole-house air conditioning system "Airful." **Features of Airful:** - Removes pollen, house dust, and cigarette odors - Eliminates discomfort caused by temperature differences *For more details, please refer to the PDF materials or feel free to contact us.*

I would like to introduce the impact of ventilation on homes and the human body. Air becomes polluted simply by people breathing. Therefore, if there is no ventilation, dirty air accumulates in the room for long periods, causing not only unpleasant odors but also health issues such as the spread of allergens and viruses in the air. Additionally, the lack of dry, clean air entering the room leads to moisture buildup, which can cause condensation and mold. Ventilation is extremely important not only for maintaining a comfortable indoor environment but also for deodorization and preventing mold and allergies. When considering renovations or remodeling, why not think about implementing a whole-house 24-hour ventilation system called "Airful" as a measure against condensation, heat shock, and house dust? **Features of Airful:** - Removes pollen, house dust, and tobacco odors - Eliminates discomfort caused by temperature differences *For more details, please refer to the PDF materials or feel free to contact us.*
