Genuine Atlas Copco 1080421404/1080424704 Fan Motor Assembly for GA37+ / GA45+ Compressors

As a leading specialist dedicated to providing complete Atlas Copco air compressors and authentic spare parts, we focus on keeping your industrial production running smoothly and efficiently. In any screw air compressor system, maintaining optimal operating temperatures remains paramount to preventing unexpected downtime. Specifically, the genuine Atlas Copco cooling fan motor assembly ensures consistent, high-velocity airflow to protect your vital machinery from overheating under heavy workloads.

Technical Specifications and Core Data

To help site managers and procurement professionals verify the precise technical alignment with an existing cooling deck, we have detailed the official electrical and mechanical specifications of this authentic Atlas Copco component below:

Direct Interchangeability and System Evolution

Moving forward to part identification, many maintenance teams notice two distinct part numbers listed within their equipment manuals. Please note that Atlas Copco officially introduces part number 1080424704 as a direct, drop-in replacement for the older 1080421404.

This part number evolution stems from minor factory upgrades to optimize supply chain efficiency and enhance internal component resilience, such as advanced bearing seals and upgraded electrical junction boxes. Because both versions share identical mounting dimensions, physical bolt hole alignments, and electrical ratings, you can install either version into your Atlas Copco cooling system without any mechanical modifications.

Key Features of the Integrated Cooling Assembly

This authentic Atlas Copco fan motor delivers exceptional reliability under harsh factory environments due to its specialized industrial design:

• External Rotor Structure: The innovative space-saving design integrates the fan blades directly onto the rotating outer shell of the motor, which maximizes space efficiency inside the compressor cabinet.
• Aerodynamic Silence: The 400 mm blade profile minimizes turbulence, allowing the system to deliver maximum cubic feet per minute (CFM) of cooling air while maintaining low acoustic noise levels.
• Heavy-Duty Insulation: Class F/H insulation protection shields the internal copper windings against high ambient temperatures commonly found in closed compressor rooms.

Frequently Asked Questions

To further address common technical and sourcing inquiries from our global customers regarding these specific cooling components, we have compiled the following helpful guide:

Q: Can I use part number 1080424704 to replace 1080421404 directly in my air compressor?

A: Yes, absolutely. Atlas Copco cross-references these two numbers as fully interchangeable engineering supersedences. The newer version offers the exact same physical fit, structural integrity, and electrical performance as the original part.

Q: How do I ensure this specific fan motor assembly fits my GA series compressor?

A: This 0.83 kW integrated fan assembly typically serves the Atlas Copco GA37+ and GA45+ premium models. To guarantee a perfect match and avoid model configuration errors, we highly recommend providing your compressor’s official serial number to our service specialists prior to completing your request.

Q: Are these components authentic factory products or aftermarket reproductions?

A: We specialize exclusively in genuine Atlas Copco equipment, complete compressor systems, and authentic replacement components. Utilizing these factory-approved parts ensures your machinery maintains its factory-level efficiency, operational safety, and warranty standards.

Q: What vital installation step must the maintenance team perform during replacement?

A: Upon completing the mechanical installation, the electrical team must perform a quick “jog test” (momentary power activation) to verify the correct fan rotation direction. If the fan spins backward and pushes air into the machine instead of exhausting it outward, simply swap any two incoming power phases (U, V, W) in the junction box to correct the rotation.
