About Listing Labels
Louvers that meet the stringent requirements of Miami-Dade County, the state of Florida or other hurricane-prone areas should be listed by AMCA International. This listing verifies that the louver can withstand the impact of an eight-foot, 2 in. by 4 in. plank of wood traveling at up to 80 ft/s or effectively keep a mechanical room dry during a storm with winds up to 110 mph. See AMCA Publication 512 for details or call staff at the AMCA headquarters at 847-394-0150.
It is important to keep up with Title 24 requirements when selling economizers and air handlers in California. Economizer dampers and outside air dampers must now be AMCA Leakage Class 1A, 1, or 2. By placing labels on the outside of this equipment, code inspectors can easily identify low leakage dampers.
