Nilfisk Grey-Line IVB5 M and the Nilfisk IVB7 M wet and dry industrial vacuum cleaner PC board with hose diameter selector and beeper. The board senses the loss in air-flow, due to blocked bag or filter. It is for both the TYPE M and TYPE H versions such as the Nilfisk IVB7 H
The beeper is designed to direct the users attention, that the filter needs to be put through a cleaning cycle.
Please note, this is NOT the correct board for the Nilfisk-ALTO XTREME 560-21 XC and 760-21 XC XtremeClean wet and dry vacuum cleaner, they use a different board WHICH DOES NOT HAVE A BEEPER
SAFETY WARNING! All electrical parts should ONLY be fitted by an electrically COMPETENT person.
