16-Outlet Double-Row Ventilation Manifold and Air Distribution Box

A 16-outlet double-row HRV distribution box is a high-capacity ventilation manifold designed for large-scale HVAC distribution systems, providing balanced airflow from a central main duct to sixteen separate ventilation points. The defining feature of this model is the double-row arrangement of the branch connections. This structural design makes the multi-channel node significantly more compact (casing width of 301 mm). Depending on project requirements, the manifold can be equipped with galvanized steel (OC), plastic (PK), or rubber (GM) branch connections.

Where is it used?

This double-row manifold is utilized in high-performance heat recovery ventilation (HRV) systems within spacious residential properties or commercial premises. The double-row layout is optimally suited for routing ductwork inside technical cabinets, wide wall niches, and suspended ceiling voids where it is necessary to save lateral space while maintaining high system capacity.

Design Features and Benefits

• Load-resistant steel casing: The durable galvanized steel resists corrosion and withstands mechanical loads during concealed installation within structural materials.
• Space-saving footprint: Arranging the 16 outlets in two stacked rows significantly reduces the overall lateral dimensions of the distribution node compared to single-row alternatives.
• Condensation protection: To prevent internal condensation in unheated zones or systems supplying cold outdoor air, insulated versions (index I) featuring a built-in mineral wool layer are available.

Branch Connection Options

The selected material for the branch connections defines the duct fixing method and the overall characteristics of the junction:

• OC (Galvanized steel): A classic, high-strength solution. Rigid metal branches provide maximum mechanical integrity and reliability 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 secure retention of flexible ducts. Plastic components have low thermal conductivity, reducing the probability of thermal bridging at the joints.
• GM (Rubber): Branches feature elastic seals for a friction-based, airtight fit. This design ensures the tightest possible connection, guaranteeing a high airtightness class across the entire ventilation network.
