• Highlight: Ametek 116474 is a 2-stage 5.7" 120V bypass motor with tangential discharge — same platform family as the 116472, specified without the ball-bearing upgrade for OEMs targeting a lower-cost build.
• Best For: Replacement service in commercial uprights, canister vacuums, and central-vac power units that originally shipped with a 5.7" tangential-discharge bypass motor.
• Expert Note: Tangential discharge routes the exhaust radially out the motor side, which keeps the through-flow path open for wet-recovery and high-CFM dust collection setups.
