Effective Ventilation: Introduces outdoor air into indoors, whilst expelling the indoor stale air to outdoor.

High efficient energy recovery: The built-in high efficient heat exchanger can recover the energy from outgoing indoor air to coming fresh air while ventilating. It can recover over 70% energy.

Silent design: It is designed with the worldwide fashionable structure and manufactured with use of accurate moldings. According to the principle of hydrokinetics, it achieves the perfect silent effect by using the micro-punch anechoic technology.

Air filtration and purification: The inner air filters are professionally designed to remove the pollutants from the incoming air, providing fresh and clean air.

By-pass function: By-pass function enables the unit to switch to natural ventilation in suitable climates, prolonging the service life of the heat exchanger.

High airproof feature and easy maintenance: The heat exchanger is connected with the equipment by the in-mold rail, and embedded with special soft and dense sealing materials. It can be removed by hand and is easy to maintain. Additionally it will ensure the outdoor air and exhaust air are completely separated, avoiding any cross contamination.
