Smoke Vents

Aluminum

SVA: Aluminum
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.

Acoustical

STC45: Acoustic
Nystrom STC45 Series Our innovative two-door construction offers many advantages over the conventional four-door design. Designed for ease of installation, our smoke vent requires fewer field adjustments than a traditional four-door model. The Nystrom acoustical smoke vent can be connected to the building's life safety system. After a fire drill, a person on the roof can safely close the two doors from the top of the vent, or by using a 3-button control from as far away as the basement. Once the alarm system has been tested, it is easy to reset the smoke vent over and over again. Our smoke vent walls are constructed of a high-technology composite of acoustical materials, which blocks sound more efficiently than the insulation that our competitors use in their smoke vent walls. This composite material in the walls, in combination with our specially designed gasketing system between the cover and the curb, provides maximum sound attenuation. STC-36 Also available.
