Product details
The Lamb Ametek 116213 is a 5.7 inch, two-stage tangential bypass motor built to run on a 240 volt supply inside central vacuum power units, the kind of motor found inside the wall-mounted or garage-mounted canister that powers a whole-house ducted system. Two stages of fan wheels stacked together give this motor meaningfully higher water lift than a single-stage motor of the same diameter, which matters most on central vacuum runs with long duct lengths or multiple floors between the power unit and the wall inlet.
Bypass cooling keeps the motor's own cooling air separate from the dirty airstream it pulls through the system, so the windings stay cleaner and the motor tends to run cooler over long duty cycles than a thru-flow design would. The manufacturer's published data for the 116213 gives 97.4 inches of water lift, 99.1 CFM of maximum airflow and 304 air watts, drawn at 4.7 amps on a 1125 watt power level. Motors at this diameter and rating are the ones fitted to central vacuum power units sold under the Beam, NuTone, AirVac, AstroVac, CanaVac, and DuoVac names.
Replace a central vacuum motor in this category once water lift and airflow have dropped noticeably even after the filter or bag has been checked and the hose and tubing have been inspected for blockages, or once the motor develops a grinding noise or a burning smell that points to worn bearings or brushes. This listing does not confirm which specific power unit model your system uses, so verify your existing motor's diameter, stage count, and voltage rating against this one before ordering.
