• Highlight: Ametek 116472 is a 2-stage, 5.7" diameter bypass motor with tangential discharge and ball bearings — a long-running OEM workhorse for commercial vacuum and central-vac OEM builds.
• Best For: Replacement and OEM use in commercial upright vacuums, central-vacuum power units, and wet/dry recovery vacuums calling for a 5.7" two-stage 120V bypass platform.
• Expert Note: The bypass design keeps the cooling air separate from the working air, which is what lets the 116472 tolerate dust-laden or wet-recovery service without shortening brush life.
