SPECIFICATION: Version: DTS Diameter [mm]: 125 Air flow [m3/h]: 140 Sound pressure: 1 m- 36 dB 3 m- 34 dB Power supply voltage: 230V, 50 Hz Motor power [W]: 14 Revolutions [1/min] (+-200): 2400 Protection rating: IP X2 The panel replacement system is simple and allows for washing or replacement whenever necessary. The click panel mounting system and ball bearings allow for safe mounting of our dRim also on the ceiling. The unique shape of the fan blades results in virtually silent operation. The motor has thermal protection on the winding to protect the device from overheating. A check valve can be added to the dRim fan, which prevents backdraft, and thus cooling and soiling of the room. TS Turns on 3 minutes after power is applied (e.g. turning on the light on a common switch) If the power is cut off during this time, the fan will not turn on. If power is still supplied after this time, the fan will turn on and run until the power is turned off plus for the time after set on the controller. Useful when the user enters the room for a moment, e.g., to wash their hands or pick up an item. The fan requires a three-wire cable because the control cable must be connected. **
