Ametek 120V Vacuum Motor, 2 Stage
This 120V, 2-stage motor is noted for a compact 5.7-inch diameter and peripheral discharge with 84.3 CFM of airflow. It’s suitable for central vacuums and certain commercial applications where space is at a premium but power remains essential. The design supports systems requiring a straightforward, motor-only replacement rather than an entire unit rebuild.
Best for: installations needing a compact 2-stage motor with solid airflow for central vacuums or compact commercial cleaners.
Why selected: The combination of 5.7″ diameter and 84.3 CFM offers a balanced option when a larger motor isn’t feasible.
Caution: Check compatibility with peripheral discharge requirements and ensure electrical wiring matches 120V operation.
116472-13 116472-00 Vacuum Motor
Designed as a 2-stage, 5.7-inch motor delivering up to 112 CFM, this replacement suits central vacuums, boat lifts, industrial cleaning, and bathing systems. It emphasizes robust suction for demanding environments while prioritizing quiet operation and energy efficiency.
Best for: high-demand central vacuums and marine or industrial systems that require sustained, strong airflow with relative quiet operation.
Why selected: The 112 CFM figure and 5.7″ form factor provide a reliable upgrade path for larger central vacuum setups and lift-driven applications.
Caution: Confirm that your system expects a 5.7″ motor with compatible mounting and discharge configuration.
Ametek Lamb AV20 8.4″ 2 Stage Vacuum Motor
This 8.4-inch, 2-stage Lamb vacuum motor is designed for durable central vacuums and related equipment. The model is identified with Manufacturer Part# 122176-18 and operates at 115VAC with a bypass configuration. It’s a practical choice for facilities needing a robust, serviceable motor that can be mounted in standard central vacuum assemblies.
Best for: installations requiring a larger-diameter motor with a bypass design for steady, high-volume cleaning tasks.
Why selected: The larger diameter can support higher airflow in setups with space for a bigger motor, and the bypass configuration can assist in cooling and durability.
Caution: Verify compatibility with bypass wiring and ensure the physical dimensions align with the existing housing.
116392-00 116392-01 Vacuum Motor
Offering 2-stage, 120V operation with a 5.7-inch form factor, this motor emphasizes high power while aiming for quiet operation. It’s positioned as a compatible replacement for several central vacuum and industrial cleaning systems, including those used in boat lifts and heavy-duty environments.
Best for: central vacuums and industrial cleaning setups that require reliable 2-stage power with quiet performance.
Why selected: The 5.7-inch size aligns with many standard housings, helping minimize compatibility issues during replacement.
Caution: Ensure your unit’s mounting points and electrical connections match the replacement specifications.
Buying Guide: How To Choose A 2-Stage Vacuum Motor Replacement
- Compatibility: Check model numbers, dimensions (diameter and depth), discharge type (peripheral vs. inline), and mounting patterns to avoid fit issues.
- Airflow And Power: Look for CFM ratings to match your cleaning demand. Higher CFM suits large spaces and heavy debris; lower CFM can suffice for compact areas.
- Noise And Efficiency: If quiet operation matters (homes, offices, or hospitals), prefer motors advertised as low-noise and energy-efficient.
- Voltage And Wiring: Ensure voltage (120V in these examples) and wiring configurations align with your electrical setup to prevent safety problems.
- Durability: Consider motor housing size, cooling design, and whether the unit supports bypass or continuous-duty operation in industrial contexts.
- Installation Footprint: Measure the space where the motor sits, including clearance for fans and intake, to avoid obstruction after installation.
FAQ
- What defines a 2-stage vacuum motor?
It uses two rotor stages to compress air and generate higher suction with improved efficiency. - Are these motors suitable for boat lifts?
Yes, several options are marketed for boat lifts and industrial cleaning, offering robust airflow and quiet operation. - How do I know which motor fits my model?
Check the exact model numbers, dimension specifications, and discharge type listed by the manufacturer. - Is 120V common for central vacuum motors?
Yes, 120V is a standard voltage for many residential and commercial vacuum motors. - Can I mix different brands for replacement parts?
Compatibility depends on physical dimensions and mounting patterns rather than brand alone; confirm fit before purchasing. - What if my unit is very loud after replacement?
Investigate motor mounting, insulation, and any housing gaps that could amplify sound; a quieter model may be needed.
