Product details
A weakening motor is the most common reason a central vacuum system loses suction, and the 115519 is Lamb Ametek's motor for power units built to run on it, sold here as part 200X, 220-240 volt.
Lamb's published specification for the 115519 gives two fan stages on 220-240 volts, 5.3 amps, 324 air watts, 107.3 CFM and 97.2 inches of sealed suction, on a 7.2 inch bottom diameter. It supersedes nothing else, and the units it went into include Modern Day, Central Vac Int. and Filtex.
Before ordering, pull your old motor and check the number stamped on its housing, which may read 115519, 5519, or 11-5519, and confirm your unit runs on 220-240 volt power, since Lamb built other motors in this family for 110-120 volt systems.

Watch for the usual signs a motor is failing: the unit's breaker tripping repeatedly, a hot or electrical smell after a short run, or the vacuum cutting out and starting again on its own. A drop in suction that a fresh bag or filter does not fix often points here too.
