14-Outlet Ventilation Manifold and Air Distribution Box
A 14-outlet HRV distribution box is a high-capacity ventilation manifold engineered for extensive HVAC distribution systems requiring a large number of directional splits from a single central unit. This floor screed ventilation manifold (available with 160mm or 200mm inlets) ensures balanced airflow distribution to fourteen separate air outlets. The rigid galvanized steel casing provides maximum structural stiffness, allowing safe, concealed installation without the risk of deformation. 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 air distribution box is specifically designed for high-performance heat recovery ventilation (HRV) systems in large residential properties, expansive offices, and commercial buildings. Its compact footprint and ultra-flat design allow for seamless integration into areas with limited mounting space, such as suspended ceilings, wall niches, or floor insulation layers, preserving the effective ceiling height of the room.
Design Features and Benefits
- Load-resistant steel casing: The heavy-duty galvanized steel construction ensures long-term durability and protects internal air distribution channels against corrosion and mechanical pressure during concrete pouring or structural mounting.
- Universal compatibility: All fourteen outlets are precisely calibrated to securely connect with standard 75 mm semi-rigid flexible ducts used in modern radiant ventilation networks.
- Condensation protection: For systems operating with temperature fluctuations or cold outdoor air, insulated versions (index I) with a built-in mineral wool layer are available to prevent internal condensation and improve acoustic comfort.
Branch Connection Options
The selected material for the branch connections defines the duct fixing method and the overall thermal performance of the connection:
- OC (Galvanized steel): A traditional, high-strength solution. Rigid metal branches ensure the mechanical integrity of the connection. 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, significantly reducing installation time. Plastic components minimize heat loss and eliminate the risk of corrosion at the joints.
- GM (Rubber): Branches feature elastic seals for a friction-based, airtight fit. This design ensures high airtightness of the ventilation system and contributes to vibration dampening within the air distribution box.
