SSD-AF - Class I & II / Airfoil Blade Damper

(Not available in the US)

Ratings and installation types may vary with construction.  Please review submittals and installation instructions prior to application.

The SSD-AF has been designed and tested to exceed all UL, ULC and NFPA requirements for smoke dampers.  These UL leakage rated dampers are intended for use in engineered smoke control systems to provide low pressure drop (open position) and extremely tight shut-off (closed position).

UL 555S and ULC S112.1 listed and labelled as Leakage Class I / Class II rated smoke damper with airflow in both directions. Exceeds NFPA 90A & 92 smoke damper requirements by providing excellent control of smoke movement or containment as needed, and is recommended for applications that call for tight sealing requirements.

The SSD-AF’s streamlined airfoil blades provide low pressure drop and reduced air turbulence for quiet operation.

The SSD-AF may be equipped with factory-installed electric or pneumatic operators.
