Juno JDA2420W is a versatile kitchen appliance that can be used for various purposes. It can be used as an external exhausting model (suction) or a recycling model (filtering). In the external exhausting model, the air is expelled outside by means of pipes to be connected to the coupling ring. On application with the unit, a non-return smoke valve is supplied to be mounted on the coupling flange. In the recycling version (filter), the air is filtered through a carbon filter and recycled into the room. The filtered air is discharged above the wall cabinet.
