Circuit board mains filter - universal
A mains filter circuit board, like this one, can be found in our vacuum units. It is needed to filter out any electrical noise and interference that comes in through the power network. Sometimes noise and interference is emitted from the unit itself. A mains filter circuit board helps reduce electromagnetic interference, allowing our appliances to function more efficiently and reliably.
In the past, we had different mains filter circuit boards, one for dual-motor units and one for single-motor units. Nowadays, we have only one mains filter circuit board, which is universally applicable to our current models, as well as to our earlier models.
