Anti-odour metal sleeve for Ona Block 125 mm

The anti-odour metal sleeve with internal structure is a metal connector sleeve for Ona Block to be placed in the air duct just before the outlet to the street. Also compatible with Zerum Block.

By placing the metallic anti-odour sleeve with the ONA block at the air outlet we will achieve a cleaner extraction, with much more discreet and softer odours.

*For use with Ona Block 170g
