Product details
The Lamb Ametek 122404-00 is a 6.6-inch diameter, 2-stage bypass motor for 120-volt central vacuum power units. The large 6.6" fan diameter delivers high airflow, rated at approximately 139 CFM with 132 inches of sealed water lift, for strong whole-home suction. Bypass cooling keeps the motor running cooler by separating cooling air from the dirty work-air stream.
- Part #122404-00 — 6.6" diameter, 2-stage, 120V
- Bypass cooling design

This Ametek-built motor is a direct fit for VacuMaid SR46, VacuMaid SR66, and VacuMaid S1660 central vacuum systems. When suction fades or the original motor fails, replacing it with the correct 6.6" bypass unit restores full performance without altering your installed ducting or wall inlets.
