Models 1604AD and 1606AD Adjustable Drainable Blade Louvers combine effective weather protection and pleasing aesthetics with airflow control, featuring operable drainable blades that provide positive airflow shutoff when closed and protection against water penetration when open. The drainable design utilizes rain gutters in the head member and each blade that divert collected water through concealed side downspouts and out the sill, effectively preventing water entrainment in the space when the blades are in the open position. Low torque, concealed linkage blade control can be operated manually or with a variety of factory mounted electric or pneumatic actuators to provide tight shut-off when desired. Suitable for use in exhaust and low to medium velocity intake applications where water penetration is a concern and airflow control is desired.
