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 performance.
Remark: The application height depends on the installation situation, see link.duco.eu/installation-height for more info.
- 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
