The Awenta PRO through-duct distribution box is designed to distribute air flow between two floors. The Ø 160 / Ø 200 mm through duct is used for air flow to the next floor of the building, while the Ø75 - Ø90 mm ducts allow connection to up to 8 ventilation ducts on the lower floor. The box is available in left and right versions to facilitate adaptation to the installation layout.

The air flow between floors is regulated by anemostats. Additionally, a damper can be installed in front of the inlet to the distribution box on the upper floor. Unused connections can be closed with the plugs included in the set.

VCBR series boxes are designed for installation in a heated area of the building, otherwise they must be insulated with a layer of mineral wool (min. 15 cm). They can be permanently embedded in screed
or ceiling or built in under plasterboard.
