This rear-flange wall exhaust shutter is for commercial buyers installing vertical exhaust ventilation. Used with compatible exhaust fans, it opens during fan operation and closes to help protect the wall opening when the fan is not running.

The shutter has a galvanized steel frame and mill-finish aluminum blades. Each blade includes a galvanized reinforcement strip along its top edge for strength and counterbalancing efficiency, plus a felt leading-edge seal for quieter closing and weather protection. It is designed for vertical mounting with direct-drive or belt-driven exhaust fans. Overall dimensions are 25 in. wide x 2.5 in. deep x 25 in. high.

Key Features:

  • Rear-flange design: Provides a wall-shutter configuration for vertical exhaust installations.
  • Galvanized steel frame: Supports use in areas where corrosion may be a concern.
  • Mill-finish aluminum blades: Creates a lightweight blade assembly within the galvanized frame.
  • Reinforced blades: Galvanized strips add blade strength and support counterbalancing efficiency.
  • Felt blade seals: Helps the blades close more quietly and improves weather protection.
  • Exhaust fan compatibility: Works with direct-drive or belt-driven exhaust fans.

Choose this 22 in. rear-flange shutter for vertical wall exhaust applications requiring aluminum blades, a galvanized frame, and compatibility with direct-drive or belt-driven exhaust fans.
