Application and Design
ESU-130 is a 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
curtainwalls, windows, doors, or as air conditioning grilles.

Free Air Velocity
Model ESU-130 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.
