Blade Type - Air Balance

Straight Blade (J-Blade)

A louver blade designed for airflow. Straight blades have minimal features for capturing water but make up for it with a flat profile. These blades minimize pressure drop during intake. If airflow efficiency is your top priority, then look no further than the straight blade.

Straight blades are available for stationary louvers and combination adjustable louvers, including drainable and non-drainable models. They are also available on our thin line louvers and grilles.
