Shrink-Out Smoke Vent Types
-
Standard Shrink-Out Smoke Vents
These units are generally used when buildings have no sprinkler system or they employ a standard sprinkler system designed to operate at 165 degrees.
-
ESF-Rated Shrink-Out Smoke Vents
Equipped with a fusible link-activated release mechanism that will ensure the unit does not activate prior to reaching the fusible link temperature, these units are designed for use with an ESFR (Early Suppression, Fast Response) sprinkler system.
