Does the Elica EAR134S2 have a recirculating vent?

Yes , the Elica EAR134S2 range hood supports a recirculating (ductless) vent , which pulls cooking air through grease and charcoal filters before returning it into your kitchen. This allows installation where external ducting isn’t available, though it may be slightly less effective at removing heat and moisture compared to fully ducted hoods.
