Commercial Air Tight Damper


Positive Seal dampers are capable to open/close mechanism as well providing air tight sealing at pressure range up to 4 inches w.g. Ideal for O/A intake, isolation as well offering modulating and shut off operation. Economically priced for high efficiency operation.

Available in both Square and Round configuration with size starting from, 8”, 10”, 12”,14”, 16”, 18”, 20”, 24”, 26”, 28”, 30”, 36”, 48” and 60”

We make custom size dampers matching to any duct sizes.


A major source of energy wastage in commercial and industrial buildings is leakage of outside air through fresh and exhaust air dampers. Conventional low leak dampers although an improvement over standard dampers are still responsible for considerable air leakage. Actual measurements through banks of conventional dampers have shown leakage in excess of 10-15% to be common occurrence. EBA’s approach to stop air leakage through fresh and exhaust air dampers is a revolutionary disc damper that results in air leakage of less than 0.001% at 4 inches of differential static pressure. Features of these include extremely low leakage, positive flow control, easy installation, long gasket life and sub zero to higher temperature applications.
