Mixed flow discharge: High induction swirl discharge intensely mixes supply air with room air. Strong supply air dilution with rapid discharge velocity decay produces draught-free, high momentum supply air motion with uniform temperature distribution over short or long throws. Ideal for enhanced thermal comfort (ADPI ≥ 90%).
Return air: Also suitable for use as a return air inlet.
Ceiling location: Air supply from above the space, integrated flush with a closed ceiling or freely suspended.
Adjustable direction: Substantially constant pressure variable air pattern modulation from horizontal to vertical via blades attached to a helically adjustable guide-ring. Horizontal discharge pattern provides draught-free cooling; vertical discharge pattern provides effective heating from elevated discharge heights.
Manual adjustment: Air pattern direction adjustment is manual.
Circular face shape: Face diameter ≥ 1.4 x DN. Suitable for plaster board ceilings or freely suspended applications.
Radial face pattern: 20 substantially radial swirl vanes provide high induction swirl discharge. Helical twist extend airflow operating range. Cambered leading edges reduce pressure drop and noise.
Metal Face: Powder coated metal finish.
Electric adjustment: Air pattern direction adjustment by means of electric actuator with 24V AC/DC power supply and 2-10 V analogue control input. Well suited to supply-to-room temperature differential control for demanding heating applications or substantial room air temperature variations.
Thermal adjustment: Air pattern direction adjustment by means of a self-acting, thermally powered, wax-bulb actuator in the supply air stream (no controls or wiring required). Manually adjustable bias with temperature scale and horizontal and vertical discharge end-stops.
Sweat Inhibitor: Thermal insulation behind face hub to prevent condensation of room air in cooling mode.
Square face shape: Lay-in tile (sizes DN250 to DN500 only) suitable for standard ceiling grids of up to 600 mm or 24".
Neck reducers: Reduce airflow duty for each neck size by approximately 30%.
