Product Information
- Low energy demand from 7.5 W due to new high-efficient motor. Maintenance-free ball-bearings contain enough grease for 40 000 hrs non-stop operation.
- Motor on special anti-vibration dampers for vibration absorbing and silent operation. Only 25dB!
- with humidity sensor (if the humidity level in the room exceeds the sensor threshold within 60-90% the fan switches automatically on and operates until the humidity level drops to the standard level, after that the fan continues operating within the set time period and shuts down), timer (the built-in run-out timer enables the fan operation within 2 to 30 minutes after the fan switching off) and a specially designed back valve (to prevent back flow and heat losses during the fan standby)
- 4 inch / 100mm nominal diameter
