8-Outlet Ventilation Manifold and Air Distribution Box
An 8-outlet HRV distribution box is a specialized ventilation manifold designed to distribute airflow from the main duct to eight separate air outlets. The rigid galvanized steel casing provides essential structural stiffness and corrosion resistance. This model is universal and can be supplied with three types of branch connections: galvanized steel (OC), plastic (PK), or rubber (GM).
Where is it used?
This HRV distribution box is widely used in residential and commercial heat recovery ventilation networks. Its flat, low-profile design allows for installation in areas with strict space limitations, such as suspended ceilings, wall niches, or floor screeds. The outlet configuration is designed to provide balanced airflow distribution across all channels.
Design Features and Benefits
- Load-resistant steel casing: Galvanized steel ensures long-lasting durability and protects the internal air distribution channels against deformation during concealed installation under structural pressure.
- Universal compatibility: All branches are precisely calibrated to securely connect with standard 75 mm semi-rigid flexible ducts used in modern HVAC distribution systems.
- Condensation protection: For systems operating with cold outdoor air, 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 polymer branches featuring special fixing rings that firmly lock the flexible duct in place. The plastic material has low thermal conductivity, reducing the risk of localized casing cooling and improving the thermal performance of the connection.
- GM (Rubber): Branches feature elastic seals for a friction-based, tight fit. This design ensures high airtightness of the ventilation system and contributes to partial vibration dampening.
