The Ametek Lamb 117939 Motor for central vacuums, blowers, and similar applications replaces all versions of the 117939 motor used in all types of industries spanning many decades. Older model 117939 motors may not be marked properly with the motor number and some may have 11-7939 or just a 7939. We do not recommend rebuilding these types of motors due to cost and technical precision for proper performance and longevity.
