DucoMax SR

DucoMax ZR

DucoMax SR is a self regulating, acoustic vent (sound attenuating ventilator), specifically engineered for situations exposed to high levels of noise disturbance. The various types are attractively designed and offer excellent acoustic and airflow performance.

  • Suited to high-rise applications
  • Four fitting depths: Corto, Medio, Alto, Largo
  • Suited to situations giving rise to high levels of noise disturbance
  • No whistling sounds with positive or negative pressure thanks to active closing aluminium valve
  • Excellent wind and waterproofing
