Product overview
Description
Exhaust louvers protect discharge openings and can be supplied with fixed weather blades or gravity backdraft blades. Gravity models open under fan pressure and close when airflow stops, reducing reverse drafts. Blade weight, hinge alignment and discharge velocity are checked to ensure reliable opening without excessive pressure loss.
