Opposed action blades are due to their characteristics preferably used for variable operation
Any intermediate sizes within the standard size range are available
Low installation effort on site since external weather louvre and multileaf damper are factory combined and assembled
Aerofoil parallel or opposed hollow blades
Operating temperature –20 – 100 °C
For very large sizes, several combinations can be arranged side by side or on top of each other
Low-maintenance, robust construction
Low differential pressure and low noise due to aerofoil blades
