Most extractors are now vented through the wall but we at NT AIR realise that not all kitchens are the same and extracting to an outside wall is not always possible.
All our chimney hoods, therefore, have the option to use a charcoal filter that attaches to the motor to help remove unwanted kitchen smells, this is an optional extra and the chimney section with the pre-cut vent must be used when outside ventilation is not possible.
Please note that maximum extraction ducting length when vented is 3.5mtrs. Also: Two Round filters will only fit the models ending in STD and RND. Square filters will only fit ALL OTHER models with the product code ending OC, CVD, ISL, ST, GL, BLK, OVL
