Stack Isolation Dampers are designed to provide accurate air flow and isolation at high temperature levels, and reduce the stack effect of a system when offline, protecting ductwork from the elements. Our Effox-Flextor brand Stack Isolation Dampers are engineered for optimal performance and efficiency, and heavy duty operations.
Flows to the stack can be voluminous and present large mechanical challenges. Our heavy-duty design ensures that blades do not flutter, shafts are steady, and they also include a unique pressure relief system that allows for opening of the non-driven blades when pressure build-up occurs. Applying decades of experience, we are able to deliver custom-designed solutions configured for your specific application requirements, providing efficient operations for a long service life.
