FDS-402

Model FDS-402 is a fabricated steel stationary drainable louver that protects air intake and exhaust openings in exterior walls. The stationary horizontal drainable blades collect and further channel water to the vertical downspouts located in the louver jambs where gravity takes effect, allowing water to escape at the louver sill.

  • 4-inch depth
  • 44% free area (4 ft. x 4 ft.)
  • 1,056 fpm free area velocity at the beginning point of water penetration
