GREENHECK AFL-601 Flush Mount - Free Area Chart

Model AFL-601 recessed/flush frame resistance to airflow (pressure drop) varies depending on louver application (air intake or air exhaust).
Free area velocities (shown) are higher than average velocity through the overall louver size. See louver selection information. (Test Figure 5.5-6.5)

Water Penetration
Standard Air – 0.075 lb/ft3 (1.2 kg/m³)
Test size 48 in. x 48 in. (1219 mm x 1219 mm)Test duration of 15 min.

The AMCA Water Penetration Test provides a method for comparing various louver models and designs as to their efficiency in resisting the penetration of rainfall under specific laboratory test conditions. The beginning point of water penetration is defined as that velocity where the water penetration curve projects through 0.01 oz. (3 g) of water (penetration) per sq. ft. (m²) of louver free area. The beginning point of water penetration for Model AFL-601 recessed/flush frame is above 1250 fpm (6.35 m/s) free area velocity. These perfor mance ratings do not guarantee a louver to be weather proof or stormproof and should be used in combination with other factors including good engineering judgement in selecting louvers.

Water penetration classification ratings are based on the amount of simulated rain that penetrates the louver during a specific rainfall rate, wind velocity, and intake velocity. Ratings are based on a 39.4 in. x 39.4 in. (1 m x 1 m) core size.
