B 250 Humidifier

The B250 help regulate the humidity levels in interior spaces. The electronic sensor allows you to see just how much moisture there is in the air. Simply set the humidistat to the humidity level that you feel is right for you or your particular application and let the fully electronically-controlled B250 do the rest.

The B 250 operates according to the cold evaporation principle: the air is drawn, cleaned and finally directed through a rotating moistened filter disc. The air absorbs the moisture and discharges back in the room.

When the water tank is empty, the B 250 shuts off automatically and a blinking lamp goes on to indicate that the tank needs refilling.
