8-Outlet Asymmetric Ventilation Manifold (Offset Inlet)
An asymmetric HRV distribution box is a specialized ventilation manifold designed to distribute airflow to eight separate ventilation points. The primary design feature of this model is the offset main inlet, positioned near the edge of the wide casing panel. This layout makes the device truly universal (L/R reversible): the manifold can be used for either left-side or right-side ducting by simply rotating it during installation. 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 engineered for heat recovery ventilation (HRV) systems with complex architectural layouts. The low-profile design (85 mm casing height) and offset connection allow for efficient mounting in narrow ceiling voids, room corners, or directly against structural walls, preserving the effective ceiling height of the premises.
Design Features and Benefits
- Universal installation (L/R): The offset inlet allows for easy left or right main duct positioning without modifying the overall ventilation scheme.
- Durable casing: The galvanized steel construction is resistant to corrosion and maintains its geometric integrity during concealed installation under structural loads.
- Acoustic and thermal protection: For systems handling cold outdoor air or requiring enhanced quietness, insulated versions (index I) are available. The internal mineral wool layer prevents condensation and provides significant noise reduction.
Branch Connection Options
The material of the branch connections determines the thermal performance of the junction and the preferred duct fixing method:
- OC (Galvanized steel): A traditional, high-strength solution featuring rigid metal branches for maximum mechanical reliability.
- PK (Plastic): Equipped with polymer branches and integrated fixing rings for fast and secure attachment of 75 mm flexible ducts. Plastic components reduce the risk of thermal bridging and condensation at the joints.
- GM (Rubber): Elastic seals ensure a friction-based, airtight fit for the ducts, guaranteeing a high airtightness class across the entire distribution network.
