The AML6 airflow measuring louver combines the functions of an outside air intake louver and an air measuring station in one compact assembly.

Its 7" (178) nominal depth requires less installation space than separate louvers and air measurement devices. The patented AML6 features a wind-driven rain resistant vertical blade louver that allows high airflow with minimal water penetration and pressure drop. It is particularly well suited for applications in air handling units as well as air plenum wall installations. The AML6 has been tested to AMCA Standard 611-95.



  • Closely spaced vertical blades that prevent the penetration of wind-driven rain.
  • Aluminum construction for low maintenance and high resistance to corrosion.
  • Maximum free area velocity is 2,175 fpm.
