18-Inch Combination Louver Damper with Flange

This combination louver damper is designed for facilities and HVAC buyers who need to protect an opening from rain and weather while allowing it to be closed when needed. It combines fixed front blades and adjustable rear blades in a single frame.

The unit has a 4-inch-deep channel frame with a 1-1/2-inch flange. Its front section uses drainable fixed blades set at 45 degrees, while rear blades include seals for tight shutoff. A thumb screw operates the rear blades, and a birdscreen is included on the back.

Key Features:

• Combined louver and damper: Provides weather protection and the ability to close the opening in one unit.
• Drainable fixed front blades: Helps direct rain and weather exposure away from the opening.
• Adjustable sealed rear blades: Allows the opening to be shut off tightly when required.
• Thumb-screw operation: Makes rear-blade adjustment straightforward.
• Rear birdscreen: Adds a screen at the back of the unit.

Choose this flanged combination louver damper for applications that need fixed weather-protection blades, an adjustable shutoff section, and a rear birdscreen in one frame.
