"BL Investments" offer s"Ventsys" window ventilation system against mold and increased CO2 concentration

After replacing the windows in buildings with natural ventilation, mold appears and the CO2 concentration increases? Perhaps the best solution is a controlled fresh air intake system and equipped with an M5 filter through all types of hinged windows- VentSys.

Main benefits:
• Easy installation for all windows, without milling or drilling, new or already installed windows.
• Equipped with M5 filters which are easily accessible for change.
• Tested for sound isolation (possibly the best in our Class).
• Complies with all LLDRA recommendations.
• Manually possible to regulate airflow
