18-Outlet Ventilation Manifold and Air Distribution Box
An 18-outlet HRV distribution box is a high-capacity ventilation manifold designed for complex HVAC distribution systems, allowing up to eighteen directional splits to be consolidated into a single compact node. The rigid galvanized steel casing ensures long-term durability and resistance to heavy structural loads. 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 widely used in high-performance heat recovery ventilation (HRV) systems across large residential properties, expansive offices, and commercial buildings. Its flat, low-profile design (82 mm casing height) allows for seamless integration into suspended ceilings, wall niches, or floor screeds, preserving the effective ceiling height of the premises.
Design Features and Benefits
- Load-resistant steel casing: Galvanized steel resists corrosion and maintains its geometric integrity during concealed installation under the pressure of structural materials and concrete pouring.
- Maximum distribution capacity: The 18-outlet configuration enables the organization of a complex airflow distribution network from a single point, significantly simplifying the main ductwork layout and reducing installation time.
- Condensation protection: For systems operating with cold outdoor air, insulated versions (index I) featuring 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 classic, high-strength solution. Rigid metal branches ensure the maximum mechanical stiffness 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 for the convenient and secure attachment of 75 mm flexible ducts. Plastic components reduce the risk of thermal bridging 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 provides partial vibration dampening within the air distribution box.
