Thin-line Louver
Frameless
Application and Design
ESU-130S is a frameless ultra thin-line stationary louver commonly
used for interior or exterior applications where high free area and low
airflow resistance is required. The narrow depth makes this product
ideal for installation into thru-wall air conditioning units.

Free Air Velocity
Model ESU-130S 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.
