EAD and EADC Louvers are designed with drainable blades for maximum resistance to water penetration. Typically operated by electric or pneumatic actuators with manual actuators available. Concealed actuator in the sill member is available (EADC). Frame depths: EAD and EADC - 4 and 6 in.
EAH Louvers have a drainable head design for increased resistance to water penetration. Frame depths: EAH-401 - 4 in.; Typically operated by electric or pneumatic actuators with manual operators available. Concealed actuator in the sill member is available.
EAH-690 is an adjustable blade louver designed primarily for exhaust applications which require maximum free area with minimum pressure drop. Blades can be specified with 0° (full closed) to 90° (full open) or 45° to 90° (full open) rotation. EAH-690 (45° or 90°) - 6 in.
The AMCA Certified Ratings Seal applies only to air performance and water penetration ratings for models EAD, and EAH-401. The AMCA Certified Ratings Seal applied to air performance for model EAH-690 with blade angle at 90°.
