Nine specifications of this series ventilator, multi-speed to control, with household and commercial use; nice exterior and affordable

It is a type of new energy-saving ventilation product which is the perfect combination of balanced heat recovery ventilation and efficient design technology.

Internal structure is composed of double-efficient unit with low noise centrifugal fan and a new two-way flow efficient heat exchange core body, therefore the superior fan performance and internal structure of the body to achieve a higher static pressure.

Ventilator unit is used a thin-shaped design and whole-house pressure balanced design with double centrifugal fan system.

It is used a new type of two-way flow of high core body heat exchange, 75% heat recovery and 25% enthalpyrecovery
