Product details
The 117500-12 belongs to Lamb Ametek's Premier line, sold here as part 203P as the replacement for central vacuum power units originally fitted with the 117500-12.
Ametek classifies it as a 7.2 inch Premier bypass motor in its high-performance flow class: 120 volts, three fan stages, a tangential discharge and a 1,600 watt power level, with 833450-57 listed as the replacement brush kit. That puts it above the two-stage motors Lamb builds in the same 7.2 inch housing, which is where the extra output comes from.
Confirm the number on your existing motor reads 117500-12 before ordering, since Lamb built both Premier and standard motors that can look similar from the outside but are not interchangeable. On a motor built for this much output the first hint of trouble is usually noise rather than a hard failure, a rising whine or a rattle that was not there a month ago, followed by an electrical odor and arcing at the brush end. Treat a gradual whole-system decline in suction as worth investigating rather than waiting for the motor to stop altogether.
