Meet the Therwen 6-inch backdraft damper, a sturdy manual regulator designed to help you guide airflow within duct branches for range hoods, exhausts, and other HVAC paths. Its galvanized iron sleeve provides structure and resilience, helping it hold its shape under heat and moisture while remaining accessible for everyday adjustments. The unit is well suited for residential, commercial, and light industrial settings, offering a practical option for balancing air in active spaces without fully sealing off a duct.
Installation is straightforward: slide the damper into the pipe, secure it in an adjustable position, and hide the seam with tape. For best results, seal all connections with pipe sealant to minimize air leakage and improve overall HVAC efficiency.
Ideal for a range of applications including air conditioning lines, dryer vents, exhausts, range hoods, and heating systems. This 6-inch damper fits common ductwork and can be used across residential, commercial, and light industrial settings to help balance air flow across multiple locations in a building.
With the Therwen damper, you gain a practical tool to fine-tune how air travels through a duct system. Use it to shift air toward areas that need it, reduce unwanted drafts, and maintain steadier performance across your HVAC setup. Consider it a flexible component for hands-on balancing rather than a one-size-fits-all solution.
