The SGR-DA sliding angle damper is designed for installation
on the SGR air grilles intended for round ventilation ducts. The
damper is provided with separate clips for mounting on the
air grille.
The SGR-DA dampers provide a means to control the
air flow rate, air flow speed and air flow range. The damper
outlet grate is set at an angle to the air grille surface. The air
flow is adjusted by repositioning the damper closure behind
the damper grate.
