6-Outlet Ventilation Manifold and Air Distribution Box
A 6-outlet HRV distribution box is a specialized ventilation manifold designed for high-performance HVAC distribution systems. This floor screed ventilation manifold (160mm or 200mm inlet) enables even airflow distribution from the main duct to six separate air outlets. The rigid galvanized steel casing withstands high structural loads, allowing safe, concealed installation in floor screeds, behind false ceilings, or inside wall niches without deformation. The model is available with three types of branch connections: galvanized steel (OC), plastic (PK), or rubber (GM).
Where is it used?
This HRV distribution box with 6 outlets is widely used in residential and commercial heat recovery ventilation networks. Thanks to its low-profile form factor (82 mm casing height), the air distribution box easily integrates into areas with strict space limitations. It is an ideal solution for radiant duct systems where optimal airflow distribution must be achieved without requiring a significant reduction in room height.
Design Features and Benefits
- Load-resistant steel casing: Galvanized steel ensures long-lasting durability and protects the internal air distribution channels against external pressure during concrete pouring or drywall mounting.
- Universal compatibility: All branches are precisely calibrated to securely connect with standard 75 mm semi-rigid flexible ducts.
- Condensation protection: For HVAC distribution systems operating with cold outdoor air or installed in unheated zones, insulated versions (index I) with a built-in mineral wool layer are available to prevent internal condensation and reduce noise.
Branch Connection Options
The selected material for the branch connections defines the duct fixing method and thermal performance of the connection:
- OC (Galvanized steel): A traditional heavy-duty solution. Rigid metal branches provide maximum mechanical strength. Ducts are typically secured using standard hose clamps or reinforced sealing tape.
- PK (Plastic): Equipped with special red fixing rings, these outlets firmly lock the flexible duct in place, significantly speeding up the assembly process. Plastic components have low thermal conductivity, reducing the risk of thermal bridging at the joints.
- GM (Rubber): Branches feature elastic seals for a friction-based, tight fit. This design ensures high airtightness of the ventilation system, preventing air leaks and pressure drops.
