System Overview<\/span><\/h2>\n
\n

EC Energy Recovery Ventilator delivers balanced whole-house ventilation for residential and light commercial projects: it supplies fresh outdoor air while exhausting stale indoor air, and the heat recovery core transfers energy between the two streams to reduce heating and cooling loss.<\/p>\n

The EC motor provides variable-speed control, which keeps operation efficient and quieter across partial-load conditions. With models ranging from 90~180 m\u00b3\/h up to 480~800 m\u00b3\/h airflow, the series covers compact homes through larger whole-house and project installations.<\/p>\n<\/div>\n<\/section>\n
