SPECIFICATION: Version: HS Diameter [mm]: 125 Air flow [m3/h]: 140 Sound pressure: 1 m- 36 dB 3 m- 34 dB Static pressure up to [Pa]: 35 Power supply voltage: 230V, 50 Hz Motor power [W]: 10 Revolutions [1/min] (+-200): 2400 Protection rating: IP X2 planet eneRgy The planet eneRgy family of axial wall fans combines a clean minimalist design without visible mounting elements, making it adaptable to any room. High-quality material does not yellow over time and the variable blade geometry ensures quiet and economical operation. HSTS has a humidity sensor that the user can set within the 40 – 80% range. The fan turns on when the set threshold is exceeded (e.g., while taking a bath) and runs until the humidity level drops, plus approximately 3 minutes to maintain the effect. The fan requires a three-wire cable because the control cable must be connected. **
