Nystrom
SVA Series
aluminum smoke vents are an automatic rooftop venting system,
which releases heat, smoke and noxious fumes during a fire.
Each smoke vent will open automatically when a fusible link
inside the vent reaches 165° F. Smoke vents are spring operated
with shock absorbers to slowly open against wind or snow load.
Smoke vents can be equipped to open electrically. The smoke
vents are listed by Underwriters Laboratories. |
