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”

Tight Seal damper for Fumigation application is application where special chambers being isolated where fruits/ vegetables and other items are being stored for a prolonged time essentially maintaining product freshness. More and more seal tight/ shut off dampers like EB Air Zero leakage type are being used thereby eliminating any risk of undue leakage.

Along with Fumigation, the EB Air Zero leakage shut off damper are being extensively used for decontamination, laboratory, hospital with any air flow path that requires full shut off/seal at medium to high pressure. Many classified projects involving sensitive environment are following high quality EB Air damper given the result is proven and the product functions flawlessly for many years. Dampers are Quality certified under ISO-9001 and meeting leak standard of ASME AG-1, 2015, section DA 5141:

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.
