• Highlight: Ametek 117500-12 is a 3-stage 7.2" 120V ball-bearing tangential bypass motor configured W/HOR (with horn/exhaust outlet) — the top-tier Ametek commercial platform.
• Best For: Truck-mount and portable restoration extractors, full-size wet recovery vacuums, and central-vac power units where maximum static lift drives water removal performance.
• Expert Note: The 3-stage 7.2" Ametek is the practical ceiling for single-motor commercial vacuum design — beyond this, designers move to dual-motor parallel or tandem stacks for additional lift or flow.
