| Zusammenfassung: | A clean air apparatus includes a fan and a filter for producing a flow of clean air and for discharging the clean air from an outlet and towards a target clean area. The apparatus includes a Coanda effect device disposed at least adjacent the clean air means, which is arranged, in use, to induce a Coanda effect upon the flow of clean air. The apparatus includes guide means for guiding the clean air towards a target clean area in the form of an air curtain. A method for discharging clean air towards a target clean area in the form of an air curtain includes inducing a Coanda effect upon the flow of clean air using the Coanda effect device; and guiding the discharged clean air, downstream of the Coanda effect device, towards a target clean area in the form of an air curtain. |
