MIA Multi-port Distribution Box

米亚多孔自平衡负压式新风机 — Self-balancing multi-port fresh air distribution unit. One central unit serves 4–8 rooms simultaneously via independent Ø75 mm outlet ports — no separate fan per room, no complex balancing, automatic equal distribution.

Key Features

One Unit. Multiple Rooms.

The MIA multi-port box eliminates the need for individual fans in each room — a single ceiling-mounted unit with multiple small-diameter outlets covers the whole floor or apartment.

4–8 Independent Outlet Ports

Transparent polycarbonate casing with 4, 6, or 8 Ø75 mm outlet ports on the top face. Each port connects to a small flexible duct running to individual room grilles. Internal baffle design ensures equal pressure at every port without manual balancing.

Self-balancing Negative Pressure Design

Patented internal geometry creates uniform negative pressure at all outlet ports — automatically distributing equal airflow to each room regardless of duct length differences. No manual balancing valves required. Total flow 200–500 m³/h with 220V motor.

Residential to Light Commercial Scale

Suitable for apartments (4-port, 2–3 bedroom), villas (6-port, 4–5 bedroom), and small offices (8-port). Ceiling void installation — compact 303 × 303 mm footprint with low-profile housing. AC 220V standard, DC brushless option for lower noise.
