12-Outlet Double-Row Ventilation Manifold and Air Distribution Box
A 12-outlet double-row HRV distribution box is a high-capacity ventilation manifold designed to distribute airflow from the main duct to twelve separate air outlets. The defining feature of this model is the double-row arrangement of the branch connections. This structural solution significantly reduces the overall width of the unit (down to 251 mm), saving valuable installation space. Depending on project requirements, the unit can be equipped with three types of branch connections: galvanized steel (OC), plastic (PK), or rubber (GM).
Where is it used?
This double-row manifold is widely used in extensive residential and commercial heat recovery ventilation (HRV) systems. Thanks to its space-saving footprint, the double-row form factor is exceptionally well-suited for installation in narrow wall niches, restricted technical cabinets, vertical ventilation shafts, and other areas where lateral mounting space is strictly limited.
Design Features and Benefits
- Load-resistant steel casing: The rigid galvanized steel construction ensures long-term durability, protects against corrosion, and withstands the pressure of structural materials during concealed installation.
- Space-saving footprint: The double-row layout makes the manifold significantly more compact in width compared to classic single-row alternatives with 12 outlets, providing a critical mounting advantage.
- Condensation protection: For systems operating with cold outdoor air or installed in unheated zones, insulated versions (index I) featuring a built-in mineral wool layer are available to prevent internal condensation and improve acoustic performance.
Branch Connection Options
The selected material for the branch connections defines the duct fixing method and the overall thermal performance of the junction:
- OC (Galvanized steel): A classic, high-strength solution. Rigid metal branches provide maximum mechanical integrity and longevity 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 for the convenient and fast attachment of flexible ducts. Plastic components have low thermal conductivity, reducing the risk of thermal bridging and condensation at the joints.
- GM (Rubber): Branches feature elastic seals for a friction-based, airtight fit. This design ensures high levels of airtightness across the entire ventilation network and prevents pressure drops.
