  • Low differential pressure and sound power level
  • Resists temperatures up to 1300 °C (according to HCM curve)
  • Installation with horizontal damper blade shaft
  • Casing air leakage to EN 1751, class C

Optional equipment and accessories

  • Duct smoke detector RM-O-VS-D or RM-O-3-D
  • Integration into the central BMS with TROXNETCOM
