The Helios Fans KWL EC 1800 S Pro is a compact, floor-standing central ventilation system designed for residential, commercial, and industrial use. It features two quiet, high-efficiency EC fans with backward-curved impellers to deliver maximum energy savings. The advanced control system supports both constant airflow and constant pressure regulation for flexible ventilation management.
The unit supplies filtered outdoor air through an F7 filter, while extract air is filtered via an M5 (F5) filter before passing through the aluminium cross-counterflow heat exchanger, which offers heat recovery efficiency of up to 90%. All filters are pressure-monitored and designed for easy removal and maintenance.
Maintenance is simplified with a removable heat exchanger, and an optional integrated water heater battery is available to enhance heating performance, making the unit suitable for various climate control requirements
