Helios Fans KWL EC 2000 D Pro

The Helios Fans KWL EC 2000 D Pro is an ultra-flat ventilation unit designed for space-saving ceiling installation, suitable for residential, commercial, and industrial applications. It meets stringent hygiene and energy efficiency standards, certified according to VDI 6022 and the passive house standard. The unit is constructed from double-walled galvanized steel with 30 mm thermal and acoustic insulation on all sides.

Filter replacement is convenient through tool-free inspection openings located at the bottom of the unit. The ceiling-mounted system includes vibration-damping fastening elements to reduce noise transmission. A large aluminium cross-counterflow heat exchanger provides heat recovery efficiency of up to 90% and can be easily dismantled for maintenance.

Two low-noise, high-performance EC fans with backward-curved impellers ensure optimal energy efficiency. The advanced control technology supports both constant volume and constant pressure operation modes. Standard filtration features an ISO ePM1 55% (F7) filter for incoming air and an ISO ePM10 50% (M5) filter for extract air, both pressure-controlled and simple to replace. This ceiling ventilation unit supports airflow rates of up to approximately 2000 m³/​h.
