Features

Fan unit ultraSilence with electronic dynamic humidity sensor, with 2 speeds 60/35 m³/h air flow volume for general and trickle ventilation Spiral housing with aerodynamic and acoustically optimized radial impeller, high pressure reserve and low noise level. Noise control according to DIN 4109 T.2. Fan unit insertion without using tools with simultaneous electrical connection of quick plug connector. Energy saving motor in enclosed aluminium cast casing. Maintenance-free ball bearings for 40.000 operation hours. Flat, elegant, room-sided facia several times design awarded made from high quality polymer, white. Air filter (class G2) as permanent filter (dishwasher resistant) behind the hinged, compact facia. The built-in filter change display indicates when filter needs cleaning. Control: General and trickle ventilation. The low speed can be wired for continuous operation directly. If the set humidity level is reached the fan runs automatically on high speed until the room humidity is back to normal. Additionally to the automatic humidity control manual On/off switching with high speed, overrun timer approx. 6 min. and delayed start approx. 45 sec. Manual controlling of both speeds with switch DSEL 2 (accessory no. 1306) possible. The automatic humidity control can be deactivated with an additional switch.
