 Extruded Operable
Louvers
Applications
In extruded operable blade louvers, Airline offers the designer a
wide selection. Many combinations of blade type and angle, depth and material thickness
are available to fit almost any application. We also have a number of available methods of
operation including manual wingnut, chain, hand crank, electric and pneumatic actuators.
All of these models are available with linkage concealed in the jamb as an option.
Also available as an option are blade and jamb, seals to reduce air
leakage through the louver in the closed position.
