Hydrogarden Ducting Backdraft Joiner 125mm
This Hydrogarden Ducting back draft damper joiner ensures your airflow will only move in the direction you want it to. The flaps inside have been designed to move in only one direction with the flow of air. Should the air start to flow back through your ducting these flaps will close ensuring you do not get a backdraft of air into your growing area.
