The Dual-Flow VMC - duo is a single-unit heat recovery system designed to efficiently ventilate the air while maintaining thermal comfort and energy efficiency. It features a logical bypass, which, when activated, shuts off the exhaust fan and keeps only the supply fan running, allowing for controlled cooling of the home.

Equipped with constant-flow EC motors, the DUO can be installed horizontally or vertically and offers the option of enthalpy exchange. It supports connection of up to 12 EKKOFLEX Ø75 mm semi-rigid ducts, ensuring flexibility and compatibility with various ventilation projects.
