Hexamotion units are available in 5 different regulation programs, available with right or left access depending on airflow direction:
Hexamotion units offer 6 flow rate modulation options for optimized energy consumption:
For best performance, we recommend using Metal Spiral Ducting and Fittings. To ensure airtightness and durability:
Ducting in cold areas (e.g. loft spaces) must be insulated with at least 25mm thick material with thermal conductivity ≤ 0.04W/(m·K) to prevent condensation. Intake and exhaust ducts should be insulated even if there is no loft space. Bubble wrap insulation is not compliant with building regulations.
Complete your ventilation system with a range of compatible controls, sensors, silencers, and valves/diffusers.
