Solar 24-hour ventilation fan

Are you struggling with high airtightness and high insulation homes, dealing with winter condensation, mold, and sick house syndrome? In winter, neglecting ventilation can lead to moisture accumulation, causing condensation and mold growth, as well as contributing to dust mite proliferation. Additionally, harmful substances emitted from building materials and furniture can contaminate the air, leading to sick house syndrome. We also address the issue of ventilating vacant or unoccupied homes, achieving 24-hour ventilation without the need for power or switch operation. It is the ultimate eco-friendly ventilation fan. Ventilation airflow: The normal operating airflow is approximately 55 cubic meters per hour, capable of 24-hour ventilation for a maximum of 30 tatami mats, with a ventilation frequency of 0.5 times/hour. Room volume: 6-tatami room - approximately 23 cubic meters, 8-tatami room - 31 cubic meters. CO2 reduction: When converted to electricity usage, it results in a reduction of 3.4 kg of CO2 annually. Compared to products with similar airflow using general power sources, it achieves double the reduction at 4.5 kg of CO2.
