Acoustic Louvers Selection Criteria

Water Penetration

AMCA 500L defines the beginning point of water penetration as

the free area velocity at which 0.01 (0.0003 L) ounces of water

per square foot of free area is measured to pass through a 48"

48" (1219 mm x 1219 mm) louver during a 15 minute period.

The AMCA water penetration test provides a method for

comparing louver models and designs as to their efficiency in

resisting the penetration of rainfall under specific lab conditions.

The manufacturer recommends that intake louvers are selected

with a reasonable margin of safety below the beginning point of

water penetration in order to avoid unwanted water penetration

during severe storm or wind driven rain conditions.

Selection Criteria

Using the Pressure Drop chart, select a free area velocity that yields an acceptable

pressure drop with minimal water penetration.

1. Determine louver free area:

____________cfm _____________fpm = ____________ft2desired air flow free area velocity required louver

@ beginning point of free areawater penetration

2. Select louver size from free area chart based on louver free area from above.

3. Determine pressure drop from Pressure Drop Chart based on desired free

area velocity.
