Product details
Ametek built part 119678-00 as a 5.7 inch, 2-stage bypass motor for 240 volt use, running on sealed ball bearings. Ametek lists it with a tangential discharge and a 1650 watt power level.
A bypass motor keeps its cooling air completely separate from the two fan stages that create suction, the layout used in most central vacuum power units and many commercial machines that run for long stretches without a break. Running the two stages in series lets the motor reach higher vacuum than a single-stage unit of the same diameter, and sealed ball bearings are built to hold up under that longer duty cycle better than sleeve bearings would.
When a bypass motor like this starts pulling less air or getting louder, worn bearings or brushes are almost always why, not a wiring fault. A correctly matched replacement is what brings the system back to its original airflow and pressure.
