Beam / Smart PU371 Control Board for Central Vacuum Power Units Modern Day tired filter media is oftenThis is a genuine Beam Smart control board (Part #312300), the printed circuit board used in the Beam and Smart PU371 central vacuum power units. It is the electronic control module that manages the unit's switching and power circuitry.
