Built to meet rigorous industry standards, the **Century Electric 173719-20** stands as a dependable workhorse, offering a perfect balance of performance, efficiency, and durability for a wide range of air compression needs.

### **Pros and Cons of buying a Century Electric 173719-20 (Magnetek/5HP, 3450 RPM, 56 Frame) Air Compressor Motor**

1. **Reliable Brand Reputation** Century Electric is a well-established manufacturer known for durable industrial motors, particularly in air compressor applications. Their Magnetek-branded motors are often favored for their robust construction and efficiency.

2. **High Power Output** The 5HP (horsepower) rating provides sufficient power for most small to medium-duty air compressor systems, making it suitable for workshops, garages, or light industrial use.

3. **Standard 56 Frame Size** This frame size is widely compatible with many air compressor models, making it easier to find replacement parts, belts, and accessories if needed.

4. **3450 RPM Speed** The motor s speed is optimized for belt-driven air compressors, ensuring efficient power transfer and reducing wear on connected components.

5. **Energy Efficiency** Modern Magnetek motors often incorporate energy-saving features, such as improved windings and magnetic materials, which can lower operational costs over time.

6. **Easy Installation** The motor s design is straightforward, and many users report that it can be installed without extensive modifications to existing setups.

7. **Long Lifespan** With proper maintenance, these motors are known to last for years, especially in applications where they are not subjected to extreme stress.

8. **Widely Available** Due to its popularity, parts and replacements are relatively easy to source, reducing downtime if repairs are needed.

1. **Cost** While not excessively expensive for a 5HP industrial motor, it may still be a significant investment compared to smaller or less powerful alternatives. Pricing can vary based on brand, condition (new vs. used), and seller.

2. **Noise and Vibration** Like most electric motors, this one may produce some noise and vibration during operation. If installed in a space with noise sensitivity, additional soundproofing may be required.

3. **Maintenance Requirements** Motors, especially in demanding environments, require regular maintenance, such as lubrication of bearings, belt tension checks, and cooling system upkeep. Neglecting maintenance can lead to premature failure.

4. **Compatibility Issues** While the 56 frame size is common, not all air compressors will have an exact match for mounting or shaft dimensions. Custom adapters or modifications may be necessary.

5. **Energy Draw** A 5HP motor consumes a substantial amount of electricity, which could increase operational costs, particularly in facilities with high energy rates.

6. **Potential for Overloading** If the motor is paired with an air compressor that exceeds its recommended capacity, it may overheat or fail prematurely. Always ensure the motor s HP rating aligns with the compressor s requirements.

7. **Limited Warranty (if purchasing used)** If buying a used or refurbished motor, the warranty may be void or limited, leaving you responsible for repairs if issues arise.

8. **Weight and Bulk** The motor is relatively heavy (typically around 100 150 lbs), which can make installation or relocation more difficult without proper lifting equipment.

### **Conclusion and Recommendation**

The **Century Electric 173719-20 (Magnetek/5HP, 3450 RPM, 56 Frame) air compressor motor** is a solid choice for those needing a dependable, mid-sized motor for industrial or workshop applications. Its reputation for durability, compatibility with common air compressors, and efficient performance make it a practical investment for users who prioritize reliability over cost savings.

- **Buy it if:** You need a high-quality, long-lasting motor for a small to medium air compressor system, and you re willing to invest in a reputable brand. Ensure the motor s HP matches or slightly exceeds your compressor s requirements to avoid overloading.

- **Avoid it if:** You re operating in a noise-sensitive environment without soundproofing, or if you re on a tight budget and can find a similarly rated motor from a less expensive brand with comparable reliability.

- **Consider alternatives if:** You need a motor for a very high-demand application (e.g., continuous heavy-duty use) or require a quieter, more energy-efficient model, as there may be newer or specialized options available.

For most users, this motor strikes a good balance between performance, durability, and availability, making it a recommended purchase for those who value quality and longevity in their equipment. Always verify compatibility with your specific air compressor setup before purchasing.
