The unit is designed with ease of maintenance in mind, allowing quick removal of the heat exchanger and filters. An optional integrated warm water heating coil can be added for energy-efficient post-heating of the supply air.

Ideal for compact vertical installations, this model ensures clean, demand-controlled ventilation with high heat recovery performance and modern control flexibility
