Parallel blade dampers are composed of several blades that each turn on their own axis. Thanks to the mechanism that joins them, these blades rotate at the same time in parallel. Depending on the customers needs, the blades can be flat or hollow (airfoil profile). The flat profiles are reinforced to be sufficiently rigid, without significantly affecting load losses. The airfoil type profiles are reinforced on the inside, not being in contact with the fluid.
Parallel blade dampers, are formed by numerous blades that turns on its own axis. Thanks to the mechanism that joins them, the blades turns in parallel at the same time.
