Product details
Part 209-1R, the Lamb Ametek 119953, is a single-stage central vacuum motor with a 5.7 inch bottom diameter. MD publishes it at 110 inches of water lift, 102.7 CFM, 384 air watts and 12 amps on 110-120 volt power, standing 5-7/8 inches tall with a bolt height of 2 inches. Ametek's own model data agrees on the single fan stage, rates the motor at 1,325 watts and names 833392-67 as the replacement brush kit.
One fan wheel instead of two or three keeps the motor short, which matters when a power unit has limited headroom above its motor mount, and it trades away some water lift for that. MD gives the expected service life of this motor as 800 to 900 hours, shorter than the 900 to 1,200 hours it quotes across most of the multi-stage Lamb range.

A sealed vacuum motor is not repairable, so every sign of a failing one points the same way. Suction falling off while the rest of the system is intact, an electrical smell, heavy blue sparking visible at the top vents, or a unit that cuts out and runs again later all mean replacement. Match the stamped number, the bottom diameter and the bolt height on your existing motor before ordering.
