Ductless Type 1 Ventilation System passiv 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.
