8-Outlet Ventilation Manifold and Air Distribution Box (Flat Inlet)
An 8-outlet HRV distribution box with a flat inlet is a specialized ventilation manifold designed for balanced airflow distribution to eight separate ventilation points. The key feature of this model is its rectangular inlet, which allows for direct connection to flat ventilation ducts. This eliminates the need for additional round-to-flat transitions. Depending on installation requirements, the unit can be equipped with galvanized steel (OC), plastic (PK), or rubber (GM) branch connections.
Where is it used?
This air distribution box is specifically developed for heat recovery ventilation (HRV) systems where saving installation height is critical. The flat rectangular connection makes this manifold an ideal solution for installation within concrete floor screeds, tight suspended ceiling voids, or shallow wall niches where standard round ducts would be too bulky.
Design Features and Benefits
- Direct flat duct connection: Eliminating extra adapters saves mounting space and reduces the overall aerodynamic resistance (pressure drop) of the ventilation network.
- Load-resistant steel casing: The rigid galvanized steel construction protects the device from corrosion and withstands high mechanical loads during installation in floor screeds.
- Condensation protection: For installations in unheated zones or for systems handling outdoor air, insulated versions (index I) featuring an internal layer of mineral wool are available to prevent moisture buildup.
Branch Connection Options
The material of the branch connections determines the characteristics of the junction and the duct fixing method:
- OC (Galvanized steel): Classic rigid metal branches providing maximum mechanical strength for the connection. Ducts are typically secured using standard hose clamps or reinforced sealing tape.
- PK (Plastic): Equipped with polymer branches featuring special fixing rings to securely hold the flexible ducts. Plastic components have low thermal conductivity, minimizing the risk of condensation at the joints.
- GM (Rubber): Elastic seals ensure a friction-based, tight fit, guaranteeing a high airtightness class for the entire distribution node.
