★Automatically adjusts ventilation airflow according to indoor CO2 concentration★Ultra-quiet 13–29dB★Approximately 4 units installed for a 30-tsubo area★Test report based on German DIN standards included.
The first type of decentralized heat exchange ventilation system "VentSun 'ZERO'" has a heat exchange rate of 87% (at an airflow of 70%). Decentralized means ductless. There is no need to run ducts in attics or similar spaces, allowing for greater design flexibility. Additionally, unlike typical wall-mounted heat exchange ventilators, it manages the entire living space, making it less likely to create temperature differences between rooms. ★ The first 10 customers will receive a heat exchange element of the same size as the product (with a sensory dryer included). ★ ZERO achieves the highest quietness in the VentSun series with a maximum noise level of 29 dB (existing models have a maximum of 36 dB). It also reduces external noise by up to 56 dB. ★ The fan is equipped with a standard wind pressure response sensor. When the wind becomes stronger, the fan's rotation automatically increases. ★ All models come standard with a freeze prevention sensor. When the heat exchange element drops below 5°C, it automatically switches to exhaust mode until it rises above 5°C, preventing freezing and condensation accidents within the system. ★ A CO₂ demand control sensor can be installed.

Company information
Edifice's main products are ventilation systems from Germany's inVENTer and Sweden's Volution Sweden AB. These two companies are part of the Volution Group, which supplies ventilation products to the UK, Europe, and Australasia (Australia, New Zealand, and other parts of Asia). This message was sent to Japan from Germany's inVENTer when the company was founded. Our company has been developing decentralized (ductless) heat exchange ventilation in Germany for over 20 years. We envision a future where our customers can breathe fresh air healthily in ultra-high airtight homes without worrying about ventilation, save energy, and live comfortably. "Simply there, that is air. We are proud to share the simple and innovative indoor environment of 'VentSaan' with many customers." Annett Witting, Chief Operating Officer of inVENTer The reason a small Japanese company came to sell products from leading European companies is due to the representative's track record in engaging in businesses that contribute to the environment. We will leverage that experience to provide helpful services.
