Adaptable Use

The S-SA2 smoke dampers are designed for mechanical or natural smoke and heat extraction systems.

Design that helps

To facilitate the installation, the S-SA2 body is fitted with single or multiple bendable brackets. They are positioned depending on the casing size and weight which simplifies the installation process and reduces the time and number of people needed.

The S-SA2 provides effective protection against smoke, fire and toxic gases when used in both mechanical and natural heat extraction systems.

To enhance the safety, it’s also able to provide a supply of fresh air to fire compartments. The S-SA2 smoke dampers are fitted with an actuator without a spring. This means they have both an open and closed safety position and require power even in the event of a fire.

The S-SA2 casing is manufactured from galvanized sheet steel. The damper blade is manufactured from calcium silicate boards. The damper outer frame contains active intumescent seal to avoid the spread of hazardous smoke and heat. Damper casing flanges are constructed for the connection of the damper to the continuous duct.
