Lamb Ametek 117123 Central ...

Product details

The 117123 replaces the 116859 motor in central vacuum power units built for 220-240 volt power, and Lamb Ametek sells it here as part 199X.

Ametek publishes both numbers in the same 5.7 inch bypass tangential range at 240 volts with three fan stages, so the two match on frame, supply and stage count. The 117123 carries a 1,550 watt power level against 1,200 watts for the 116859, which is what makes it the later, stronger part rather than a straight duplicate. Ametek lists seven suffixed builds of the 117123 that differ only in lead terminals, bearing air seal, inlet tube diameter, lead length and packing, and it gives 833423-62 as the brush kit for the common builds.

This is the correct swap whether your old motor is stamped 116859 or 117123. Confirm your system runs on 220-240 volts first, since Lamb also built 120 volt motors of similar physical size that are not interchangeable. Typical failure signs are a mini breaker that trips repeatedly, an electrical smell after a short run, sparking near the top of the housing, or a steady decline in suction at every inlet that a fresh bag or filter does not fix.
