Show moreComplete installation of the AIRUNIT GEMINI decentralized residential ventilation system. The AIRUNIT GEMINI is a decentralized residential ventilation system. The fans of the AIRUNIT GEMINI operate simultaneously in opposite directions (counter-rotating operation). It therefore consists of two separate ventilation units in one housing, which are equipped with a control unit. The air ducts of both units are structurally separated and sealed. Thus, there is no mixing of supply and exhaust air streams. Through controlled air exchange, the AIRUNIT GEMINI ensures a comfortable indoor climate and is also the perfect single-room solution for larger rooms of 20 m² - 25 m².
