Back Draught Shutter for 8" Duct Systems
The Ruck 8" Back Draught Damper is an essential component for maintaining efficient airflow in ventilation systems. Built with a durable galvanized sheet steel housing, it prevents reverse airflow by automatically sealing off when the fan is off. The spring-loaded aluminum flaps respond to active airflow and remain closed when idle, assisted by a secure rubber seal. This back draught shutter is suitable for both horizontal and vertical mounting, making it versatile for various ducting setups. Ideal for hydroponic grow rooms and HVAC systems where air control is critical.
