12-Outlet Ventilation Manifold and Air Distribution Box (Flat Inlet)
A 12-outlet HRV distribution box with a flat inlet is a high-capacity ventilation manifold designed to organize large-scale airflow distribution from a single main duct to twelve separate air outlets. The standout technical feature of this model is its rectangular (flat) inlet. This design allows for a direct connection to flat 200x50 mm or 200x90 mm ducts, eliminating the need for additional transition adapters. The manifold is available in three branch connection types: galvanized steel (OC), plastic (PK), or rubber (GM).
Where is it used?
This air distribution box is specifically engineered for high-performance heat recovery ventilation (HRV) systems in residential and commercial buildings. The direct connection to flat main ducts makes this unit the optimal choice for installations with severe height restrictions, such as narrow suspended ceiling voids, wall niches, or concealed placement within concrete floor screeds.
Design Features and Benefits
- Direct flat duct connection: Removing round-to-rectangular transitions saves critical mounting space and significantly reduces the system's aerodynamic resistance (pressure drop).
- Load-resistant steel casing: The rigid galvanized steel construction provides mechanical strength and reliable protection against corrosion, which is essential for concealed long-term installation.
- Condensation protection: For systems handling cold outdoor air or those installed in unheated zones, insulated versions (index I) featuring an internal mineral wool layer are available to prevent moisture buildup and thermal loss.
Branch Connection Options
The material of the branch connections defines the junction's thermal performance and the preferred duct fixing method:
- OC (Galvanized steel): A traditional, high-strength solution featuring rigid metal branches for maximum mechanical integrity and durability.
- PK (Plastic): Equipped with polymer branches and integrated fixing rings for the fast and secure attachment of flexible ventilation pipes. Plastic components reduce thermal conductivity, protecting the joints from condensation.
- GM (Rubber): Elastic seals ensure a friction-based, tight fit for the ducts, guaranteeing a high level of airtightness across the entire distribution node.
