Product details
The Lamb Ametek 122100 is a 5.7-inch diameter, 2-stage Acustek peripheral-discharge bypass motor for 240-volt central vacuum power units. The Acustek bypass design separates cooling air from the work-air stream for cooler, quieter running, while peripheral discharge directs exhaust around the motor housing for efficient air movement.
- Part #122100 — 5.7" diameter, 240V, Acustek series
- Peripheral-discharge, bypass cooling design
- 2-stage fan stack for strong suction and lift
This Ametek-built motor is engineered to fit the HP Products Dual Motor Model DB9000 as the lower motor position. When one motor in a dual-motor power unit fails, replacing it with the correct Acustek unit restores balanced airflow across both stages. Confirm the lower-motor location before installing to ensure proper fitment.
