Type SV Automatic Fire Vent

Picture
  • Automativ fire vents aid Firefighters in bringing a fire under control by removing smoke, heat and gasses from a burning building.
  • Type SV is ideal for applications requiring smaller vent areas.
  • Available in galvanized steel or aluminum construction and can be provided with polycarbonate domes for added daylight.

Standard Features and Benefits

  • Thermolatch® positive hold/release mechanism ensures reliable vent operation when a fire occurs. Automatically releases vent covers upon the melting of a UL-listed 165°F (74°C) fusible link. The curb-mounted fusible link housing allows the latch to be quickly and easily reset from the roof level.
  • Engineered with powerful lifting mechanisms to open the covers in snow and wind conditions
  • Heavy duty shock absorbers assure smooth opening and eliminate the possibility of operational, roofing or structural damage
  • Fully insulated and gasketed for weather-tightness
  • Constructed with corrosion resistant materials to provide many years of trouble free, dependable service
