Bubble Tight Industrial Damper


This product is generally applied to industrial shut off applications involving rugged construction capable of handling high pressure and temperature. Ideal for Labs , mining ventilation, waste water treatment plants, process applications etc. Available is various sizes to suiting site requirement.

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 zero leakage dampers, industrial dampers, butterfly dampers matching to any duct sizes.


EBA’s unique Bubble Tight Isolation Dampers (BTD) utilize the rotating disc principle that has proven very successful in many applications. The rugged industrial damper has also been developed for areas where leaks could result in hazardous conditions as well for high pressure and high temperature applications. The primary advantage of Bubble tight damper when compared to conventional butterfly valve is no metal to metal contact between dish gasket and frame also unique smother design minimizes accumulation of particulates on seals, increase reliability and lower maintenance. The dampers are built to the highest industry standards and is individually tested for zero bubble leakage against a differential pressure of 10 inches as specified in ASME N509 standard.
