B 250 – All-electronically controlled disc humidifier

Air humidifier with air filter - so much fresh air!

The B 250 – an all-electronically controlled humidifier with air filter and adjustable air discharge direction – works according to the cold evaporation principle: Air is sucked in via a filter, then cleaned and led through a wet, rotating filter disc. Here it absorbs the required humidity which is then again emitted to the room air equally and without precipitation.

Humidity control

The current relative humidity is displayed via an electronic sensor: Simply save the desired humidity value in the device; the B 250 independently assumes control.

Keyboard lock

In order to protect the humidifier against unauthorized access, input can be disabled via a keystroke combination.

Water level indicator

The control panel provides information concerning the water level. The B 250 switches off automatically when there is no water left in the tank, a flashing light indicates that water ought to be refilled.

Optional equipment of the B 250: automatic water supply, water monitor, safety pressure hose
