Main benefits
	No exhaust fan consumption Low, or no maintenance No proper noise at the terminals level Low cost ventilation solution No risk of failure (no electrical product)	Low consumption of the exhaust fan Controlled airflow throughout the year Low maintenance No proper noise at the terminals level Low criticality in case of exhaust fan failure	Airflows controlled and guaranteed all year long Possibility of having a boost airflow (kitchen) Good attenuation of noise transmitted into the air ducts Compact ventilation terminals	Airflows controlled and guaranteed all year long Additional energy savings through the heat exchanger Supply airflow very precisely managed Possibility of having boost airflow Good acoustic insulation between the dwellings through the ducts and from the outdoor Possibility of filtration Compact ventilation terminals	Airflows controlled and guaranteed all year long Additional energy savings through the heat pump Good acoustic insulation Easy maintenance thanks to filter monitoring Smart device
