The ProTeam 105164 carbon brush set keeps Domel-powered backpack vacuums running by replacing the worn carbon contacts that transfer power to the motor's commutator. Carbon brushes are a normal wear item, and when they get short the motor loses power or stops, so swapping in this set of two is the standard fix to restore full suction and extend motor life.
