意大利采购需求：低噪音、单向风、壁挂式新风系统

I'm looking for detailed information and pricing for the following ventilation products: a smart wall-mounted ductless energy recovery ventilator and a wall-mounted ductless energy recovery ventilation system equipped with a HEPA filter. We're particularly interested in understanding the specifications, features, and any certifications these units come with, as well as volume pricing and lead times for delivery to Italy. Additionally, can you provide insight into warranty options and any available accessories that complement these systems? We're keen to expand our offerings in the Italian market, so any suggestions on the best-selling models or those with unique benefits would be greatly appreciated. Looking forward to your prompt response!
