SKD-ZA

The SKD‑ZA combination diffuser provide space‑saving and effective ventilation by integrating supply and extract air in a single compact product. The diffuser is available in a circular or square design.

Supply air is distributed through the radially arranged air deflectors, while extract air is removed via the centrally positioned control valve.

The diffuser face connects to an internally separated plenum box, which is configured according to the required size and air flow. Thermal insulation is integrated between the supply and extract air sections within the plenum box.

This compact combination diffuser is particularly suitable for installations where only a single wall or ceiling opening is available due to construction or installation constraints, with wall‑mounted use being especially common.

The adjustable air deflectors are designed to reliably prevent short‑circuiting between the supply and extract air.

Under appropriate conditions, the extract air control valve can also function as an overflow grille, even without a direct duct connection.
