AHU 400 Himling is a ventilation unit in Ensy’s AHU series. The right and left variants of AHU 400 Himling have a capacity of approx. 400 m³/h and are well suited for apartments/small houses and single-family homes. The models are based on the best available technology, which here has resulted in: Energy efficiency and low noise level. Very user-friendly control as well as an appealing design. AHU-400 Himling is built for ceiling mounting, alternatively wall mounting. The AHU units are of course developed to meet the requirements of today’s regulations. In addition, the units meet the requirements of the Passive House standard. Control panel with 10 meter cable is supplied loose together with the AHU unit.
