Ideal and reasonably priced choice for replacing worn out common dampers.
Caution: In applications where the humidity level is unusually elevated, or where there are extremely high levels of dust and dirt particles, we recommend that the damper linkage and bearing system should be cleaned once a year. This can be done easily with the use of a domestic strength steam cleaner. The loosened dirt and water droplets can then be blown out with compressed air.
Leakage does not exceed 3 cfm/ft.² against 1” w.g. differential static pressure.
