10-Outlet Ventilation Manifold and Air Distribution Box (Flat Inlet)
A 10-outlet HRV distribution box with a flat inlet is a high-capacity ventilation manifold designed for large-scale airflow distribution to ten separate ventilation points. The key design feature of this model is its rectangular main inlet, which allows the manifold to be connected directly to flat ventilation ducts without the need for additional round-to-flat transitions. Depending on project requirements, the unit is available with galvanized steel (OC), plastic (PK), or rubber (GM) branch connections.
Where is it used?
This air distribution box is specifically developed for high-performance heat recovery ventilation (HRV) systems where installation height is strictly limited. The direct flat duct connection makes this manifold an optimal choice for concealed installation in tight suspended ceiling voids, wall niches, or within concrete floor screeds.
Design Features and Benefits
- Direct flat connection: Eliminating the need for transition adapters from round to rectangular profiles significantly saves mounting space and reduces the overall aerodynamic resistance (pressure drop) of the system.
- Load-resistant steel casing: The rigid galvanized steel construction ensures reliable protection against deformation during concrete pouring and remains highly resistant to corrosion.
- Insulated versions: For installations in unheated zones or for systems handling cold outdoor air supply, insulated versions (index I) with a built-in mineral wool layer are available to prevent internal condensation.
Branch Connection Options
The material of the branch connections determines the thermal performance of the joints and the duct fixing method:
- OC (Galvanized steel): A traditional, high-strength solution featuring rigid metal branches for maximum junction durability.
- PK (Plastic): Equipped with polymer branches and integrated fixing rings for fast and secure attachment of flexible ducts. Plastic components have low thermal conductivity, providing additional protection against condensation at the joints.
- GM (Rubber): Elastic rubber seals ensure the tightest possible friction-based fit for the ducts, guaranteeing a high airtightness class for the entire distribution node.
