Greenheck FSD-312 - Manual

APPLICATION

Model FSD-312 is a high performance combination fire smoke

damper with class II leakage. High strength airfoil blades ensure the

lowest resistance to airflow in HVAC systems with velocities to 3000

fpm (15.2 m/s) and pressures to 4 in. wg (1 kPa) Model FSD-312 may

be installed vertically (with blades running horizontal) or horizontally

and is rated for airflow and leakage in either direction.
