The Electrical Control Box (EFK) is used for Lindinvent's fume hood control via the fume hood regulator FCLb. The EFK is connected to be able to cut power to, for example, power strips in the event of an alarm, after an adjustable time. Time settings and other configurations are made in the connected regulator.  

EFK can also be ordered as an accessory for bench fume hood control via the 2-position flow regulator FLLb.
