Tjernlund Ducting Editorial Review

The Tjernlund BD-4 Spring Return Backdraft Damper has garnered a mix of enthusiastic and critical feedback from customers, primarily revolving around its Construction quality and functionality versus expected air flow capabilities. Users commend the build quality, highlighting its solid Construction with a durable double-flanged rubber gasket, which enhances its effectiveness when correctly placed in systems with sufficient air flow. Many customers have noted that the damper fits securely onto standard 4-inch ducting, a feature that contributes to its appeal for various applications, including dust collection systems. However, the overarching concern among users pertains to the strength of the springs. Multiple reviewers have reported that the springs are excessively robust, making the damper challenging to activate in specific installations, particularly where air flow is weak. Customers installing it in horizontal positions, or with low-capacity fans, found the spring's resistance problematic, requiring modifications such as removing springs, which could compromise effectiveness. This, coupled with some reports of missing interior gaskets and manufacturing inConsistencies, raises questions about the overall reliability in preventing backdrafts under less-than-ideal conditions. In summary, while the Tjernlund BD-4 is seen as a high-quality, heavy-duty product suited for robust air flow scenarios, its performance may falter with lower-capacity systems unless modifications are made. **
