Uneven airflow and noise between rooms
Without proper air distribution, your HRV unit operates chaotically. Air, much like water, always looks for the path of least resistance. If a system lacks a central distribution node, the rooms closest to the unit feel a constant draft, while the furthest bedrooms still lack fresh air and accumulate carbon dioxide.
Traditional branch systems have another massive flaw – sound. If your bedroom and living room are connected by the same common metal pipe, the system acts like a telephone. You will hear perfectly what family members are saying in the next room, and the drone of the unit's fans will become a constant nighttime background noise.
Quiet and precise air division
The manifold acts as the heart of the ventilation system, dividing air equally. The large and fast airflow coming from the heat recovery unit enters a spacious box. Here, the air velocity drops drastically, the pressure equalizes, and the flow is evenly distributed into the smaller flexible ducts traveling to each room.
The radial routing system guarantees total acoustic privacy. Because a completely separate duct runs straight from the central manifold to each plenum box, sound has no direct path between rooms. The distribution box itself absorbs residual aerodynamic noise.
100% acoustic separation – a radial ventilation layout with a central manifold prevents sound transmission between rooms, ensuring peace and quiet in your home.
