The Swartwout Series damper models include round isolation/control dampers, multi-blade control dampers, multi-blade backdraft dampers, and more. The louver line includes the AFG40 Fiber-Aire adjustable fiberglass louver and the AMCA-certified model SFG40 stationary fiberglass louver. Both louvers feature flame-retardant vinyl ester-based materials of construction and PVC-coated bird screen.
