AMETEK Bypass Central Vacuu...

Product details
This is an assembled AMETEK replacement motor, part FM24742702, cross-referencing Ametek's own part number 122747-27 for 120V central vacuum power units.
Ametek's published data for 122747-27 lists it on the 6.6 Premier platform, a 6.6 in. frame, a two-stage fan, and a tangential bypass output rated in their High Performance flow class at a 1650 W power level. Two fan stages means the motor uses two impeller stages in sequence rather than one, building more vacuum pressure than a single-stage fan on the same frame size. In a bypass design, the air that cools the motor windings is drawn in separately from the dirty vacuum airstream passing through the unit, rather than sharing the same path, which is why bypass motors are the common choice in bagged, filtered power units where the incoming air still carries dust.
- Part: FM24742702 (Ametek/Lamb 122747-27)
- Voltage: 120V
- Frame: 6.6 in., 6.6 Premier platform
- Fan stages: 2, tangential bypass
- Power level: 1650 W, High Performance flow class
It arrives fully assembled, so it drops in as a straightforward swap for a failed motor rather than a kit you have to build up first. Ametek's build note for this motor calls for a matching brush kit, cross-reference 833490-78, when the carbon brushes eventually wear down and need servicing, which is worth having on hand at service time rather than ordering separately after the fact.
