• Highlight: Ametek 114787 is a 7.5-inch three-stage bypass peripheral-discharge replacement motor, the OEM-grade workhorse used in central vacuum and commercial wet/dry units that need bypass cooling for long duty cycles.
• Best For: Vacuum repair technicians rebuilding commercial units, central-vac service shops, OEMs sourcing aftermarket replacements, and contractors keeping a spare motor on the truck for same-day swaps.
• Expert Note: Three-stage bypass design separates the suction airstream from the motor cooling air, which extends motor life on extended-run commercial work by roughly 2-3x versus single-stage flow-through designs.
