1) The system is perfectly anchored to the condensate collection tray. The protection grill prevents the passage of impurities that could deposit and block the discharge of liquids. 

2) As the level of condensation increases, the floating sphere automatically rises, allowing the liquid to drain off; when the process is completed, the floating sphere automatically lowers, closing the drain and preventing the entry of bad odours or insects.

Complete with reversible basin for condensate drainage.
