Upgrade-grade power: the Lamb Ametek 117478 Premier central vacuum motor (SKU 201P) is a brand-new, two-stage, 110-120 volt Ametek original that fits every motor in the 117478 family, including the 117478-12. It can also replace the 117549 — and outmuscles it at 549 air watts versus 483, while standing just 0.18" taller. Motors marked 7478 or 11-7478 are the identical part.

Specification sheet:

  • Voltage: 110-120 V, 50-60 Hz | Amps: 13.5
  • Fan stages: 2
  • Bolt height: 1-3/4" | Overall height: 7-3/4"
  • Air watts: 549 | CFM: 115.8 | Waterlift: 120"
  • Bottom diameter: 7.2"

Rated life is 900-1,200 hours. Replace when the mini breaker pops, an electrical smell surfaces, blue sparks flare from the motor top, or the motor shuts itself down and later revives — absent any click, test the relay first. Installation comes down to three bolts plus two wire connections. Carbon brushes are replaceable on the 117478 (two required per motor) for owners who prefer preventive service.
