ETL listed for all categories of heating appliances—Category I, II, III, and IV, Building Heating Appliances, and both gas and solid fuel fireplaces—the OBD sets a high standard for safety and compatibility. At the heart of the OBD is the fastest actuator in draft control technology, custom-designed by US Draft Co. This ensures an immediate and precise response to system changes, maintaining optimal draft conditions at all times.
With a continuous temperature rating of up to 1,000˚F (1,400˚F intermittent), the OBD opposed blade damper is ideally suited for high-temperature and high-efficiency appliances. When integrated with a V-Series controller, the US Draft Co. OverDraft Control System (ODCS) leverages the OBD to maintain consistent draft within the manifold, even during overdraft conditions. This system ensures efficient and safe operation across various industrial and commercial settings.
For those seeking advanced control options, US Draft Co. offers a range of V-Series Constant Pressure Controllers and AX42 Constant Speed Controller, each designed to optimize the performance of your OBD damper system.
