Energy from nature, measures against summer heat and winter condensation! Energy-saving natural ventilation openings compatible with high airtight houses.
The eco-friendly housing ventilation outlet "Goodman" mixes indoor and outdoor air at the top of the damper on the indoor side, neutralizing the temperature and alleviating cold drafts. It provides natural ventilation effects year-round, contributing to the longevity of the house and reducing environmental impact as a passive ventilation outlet. When installed in opposing rooms facing north-south or east-west, it achieves wind-driven ventilation (airflow effect), making it effective in apartments. Even in high airtight houses, the presence of two ventilation outlets ensures constant natural ventilation effects. 【Features】 ○ Prevents air from stagnating in the upper part of the room due to temperature differential ventilation ○ Provides constant natural ventilation effects even in high airtight houses ○ Extends the lifespan of the house ○ Reduces environmental impact For more details, please contact us or download the catalog.
