A lot can fit into small space
Automated pressure difference control enables the TRDn trickle vent to automatically implement the controlled ventilation concept. It ensures appropriate, healthy climate inside while having a minimum consumption of energy.
Aerodynamic aluminium panel carries out the control function – inflowing air makes it drop or raise, controlling the flow rate. This solution ensures constant flow regardless of the weather conditions.
Despite its small size, Ventair TRDn is characterized by very good acoustic attenuation – up to 40 dB when closed!
Control is yours
Throttle enables also manual control. At any time you can increase or decrease the air flow and adapt it to your current needs.
Nominal flow ∆p = 10 Pa
- trickle vent open: 23,8 m3/h
trickle vent closed: 5,7 m3/h
Nominal flow ∆p = 20 Pa
- trickle vent open: 26,1 m3/h
