New! Counterbalanced non-return damper

Another novelty that we have included in our latest ROS Ducting catalog is a non-return damper, adjustable with a lever with a mobile counterweight.

How to use:

It must be installed in horizontal sections where there is overpressure.

Thanks to the lever with a mobile counterweight, the amount of air force necessary to open it can be regulated, thus allowing the product to circulate inside.

When the airflow stops, the damper closes instantly due to the action of the counterweight, protecting the installation from material blowback.
