Frequently Asked Questions
Q: What are the performance specifications of the AMT119891-06 vacuum motor?
A: The AMT119891-06 is a 24VDC, 2-stage tangential bypass motor delivering 80 air watts maximum power, 66.3 cfm airflow, 40.9 inches of sealed vacuum, and 15,208 RPM at nominal speed. Maximum running current is 15.6 amps. The 5.7 inch frame diameter fits standard commercial floor cleaning equipment.
Q: What equipment is the AMT119891-06 designed for, and what brands use it?
A: The AMT119891-06 is used in commercial and industrial floor scrubbers, sweepers, and extraction cleaners that operate on 24VDC battery power. It is compatible with equipment from major brands including Nilfisk, Windsor, Karcher, and other commercial cleaning equipment manufacturers. Verify the original part number and frame size on your equipment before ordering.
Q: What is the bearing construction and how does it affect lifespan?
A: The AMT119891-06 features double ball bearing construction that supports continuous duty in heavy-use commercial applications. Double ball bearings distribute radial loads evenly, reduce side-load stress, and extend motor life in vibration-heavy floor cleaning equipment compared to single-bearing designs.
Q: What are the cross-reference and equivalent part numbers?
A: The AMT119891-06 is equivalent to OEM part number 119891-06 and cross-references AK119891-06 and AK 119891-06. These are interchangeable part numbers and direct replacements for ordering and compatibility verification.
Q: How does a 2-stage motor differ from a 3-stage motor for floor cleaning duty?
A: The AMT119891-06 is a 2-stage motor, meaning it has lower airflow and vacuum than comparable 3-stage motors but draws less current and runs cooler. Use a 2-stage motor for light- to medium-duty floor cleaning. Choose 3-stage if your equipment requires higher suction for heavy debris or extended daily runtime.
