<p>The clean air zone creation system is for an operating theatre, or pharmaceutical or electronic work area etc. Inlets are distributed over it, typically at regular intervals, and connected to a unit supplying a clean air current and having purifying devices, such as filters etc. The air can be discharged from the underside, to form a downwards flowing air stream generated by fans in each corner of a rectangular housing, each fan discharging into a plenum chamber above a filter.</p> |
