AHU 300 Himling is a ventilation unit in Ensy’s AHU series. AHU 300 Himling right and left variants have a capacity of approx. 300 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-300 Himling is built for ceiling mounting, alternatively wall mounting. The AHU units are of course developed to meet the requirements in today’s regulations. In addition, the units meet the requirements in the Passive House standard. Control panel with 10 meter cable is supplied loose together with the AHU unit.
