Ductless Type 1 Ventilation System passiv Fan
Ductless Type 1 Ventilation System Passive Fan
Type 1 ventilation is not high.
**Eliminating the Challenges of Type 1 Ventilation All at Once** High-performance building materials such as insulation, resin sashes, and Type 1 ventilation are essential for energy-efficient homes, but the adoption of Type 1 ventilation has been slow. Reasons include "high electricity costs," "difficult duct installation," "limitations on space design," and "troublesome maintenance." However, with the introduction of the ductless passiv Fan, which boasts a heat exchange rate of 90%, all these challenges have been resolved. **Electricity Costs are About Half of Conventional Type 1 Ventilation** When comparing a 40-tsubo wooden house, the annual electricity cost of conventional Type 1 ventilation is about 8,000 yen. The passiv Fan has miniaturized the fan, significantly reducing power consumption to about 4,100 yen, which is half the cost. This is comparable to the electricity cost of Type 3 ventilation. With a maximum heat exchange rate of 90%, the power consumption for air conditioning and other climate control systems is also greatly reduced. After deducting the savings from power consumption, maintenance costs, and utility expenses, you can save a net of 10,480 yen annually (according to manufacturer data). **Significantly Improved Workability and Design Flexibility** Since the Achilles' heel of Type 1 ventilation, "duct installation," is not required, workability and design flexibility have greatly improved. Being made in Japan, it is compatible with conventional and 2x4 construction methods. Additionally, compared to German products, it offers higher quiet performance and is more compact.

basic information
■Free space design not constrained by ducts Since it is compact and does not use ducts, it does not interfere with space design. Designs such as atriums, skip floors, lofts, and sloped ceilings can be created freely. Moreover, the ventilation volume calculation can be done at 25㎥/h per ventilation unit, so even if there are minor changes to the plan, there is no need to recalculate the execution budget. It does not trouble the designer. ■Homeowners can perform maintenance themselves Due to its simple structure, homeowners can clean and maintain it themselves while remaining indoors. Conventional first-type ventilation systems with ducts run them through attics and other spaces. Therefore, maintenance performed once or twice a year requires opening up the ceiling or underfloor for cleaning. If you hire a contractor, it naturally incurs additional costs. The passiv Fan's heat storage element is removable and can be cleaned with water once a year. There is no need to regularly replace paper filters like conventional products, which helps reduce unnecessary expenses aside from electricity costs. Additionally, since it is made in Japan, it provides peace of mind for after-sales support, such as inquiries and parts ordering, compared to products from overseas manufacturers that are common in ductless systems.
