Non-return damper

BARAMINTEC non-return dampers are used in offshore and marine applications to prevent backflow through ventilation ductwork system.

The non-return dampers do not need an actuator or motor. Non-return dampers can be installed in rectangular or circular ducts, horizontally or vertically. If required, they can easily be set by adjusting the weight of each damper/installation. When the blades are in the open position, the device does not cause significant pressure loss, noise or flow disturbance.
