High Ceiling Swirl Diffusers
High Ceiling Swirl Diffusers
Return air: Can also be used as a return air inlet.
Ceiling position: Air supply from above the space, integrated flush with a closed ceiling or freely suspended.
Adjustable direction: Horizontal to vertical, significantly constant pressure variable air pattern modulation via vanes linked to an adjustable guide ring. Horizontal discharge pattern provides draught-free cooling; vertical discharge pattern provides effective heating from high throw heights.
Manual adjustment: Air discharge direction adjustment is manual.
Circular face shape: Face diameter ≥ 1.4 x DN. Suitable for plasterboard ceilings or freely suspended applications.
Radial face pattern: 20 radial swirl vanes provide high induction swirl discharge. Helical twist airflow extends the operating range. Curved leading edges reduce pressure drop and noise.
Metal Face: Powder-coated metal finish.
Options
Electric adjustment: Air pattern direction adjustment via electric actuator with 24V AC/DC power supply and 2-10 V analog control input. Well suited for demanding heating applications or significant room air temperature variations for supply-room temperature differential control.
Thermal adjustment: Air pattern direction adjustment via self-acting, thermally operated, wax bulb actuator in the supply airflow (no control or wiring required). Manually adjustable bias with temperature scale and horizontal and vertical discharge end stops.
Anti-sweat: Thermal insulation behind the face hub to prevent condensation of room air in cooling mode.
Square face shape: Built-in tile suitable for standard ceiling grids up to 600 mm or 24 inches (DN250 to DN500 sizes only).
Neck reducers: Reduces airflow duty by approximately 30% for each neck size.
