Product Overview
The 20-PP01080 is the original main AC fan assembly engineered by Allen-Bradley / Rockwell Automation specifically for the high-power PowerFlex 700H and PowerFlex 700S AC drive platform. Rated at 230 watts of continuous cooling power, the 20-PP01080 is the primary forced-air component charged with extracting heat from the IGBT power modules, diode bridges, DC bus capacitors, and heatsinks that sit at the heart of frame-size 9, 10, and 11 PowerFlex 700S/H drives. Inside large-frame VFDs that deliver hundreds of kilowatts to several megawatts of motor power, the 20-PP01080 is not an accessory—it is the literal lifeline of the drive’s thermal management system, circulating high-velocity air across the densely packed power semiconductors to keep junction temperatures within safe limits under full-load, continuous-duty operation.
As a genuine OEM spare, the 20-PP01080 is dimensionally and electrically matched to the original fan system installed at the factory, ensuring identical airflow characteristics, acoustic profile, and connector compatibility. This precise matching eliminates the risks associated with generic third-party fans—reduced airflow, increased bearing noise, electrical mismatch, or premature failure—that can compromise drive reliability. The 20-PP01080 is listed in the official PowerFlex 700H/700S Frame 10 installation manual as the main AC fan spare part, with documented removal and replacement procedures that allow a qualified technician to restore a drive’s cooling capacity in a fraction of the time required for a full power structure overhaul.
In the lifecycle management of a PowerFlex 700S/H drive, the 20-PP01080 occupies a critical position on the preventive maintenance schedule. Fan bearings degrade gradually over years of high-speed rotation; as the fan ages, airflow diminishes, bearing noise increases, and the drive begins to operate closer to its thermal limits—triggering over-temperature derating or unexpected fault shutdowns. By proactively stocking and replacing the before failure occurs, plant engineers protect their PowerFlex 700S/H investment, avoid catastrophic IGBT failures caused by overheating, and ensure that the drive delivers its rated output without interruption. The is therefore one of the highest-return spare parts a PowerFlex 700S/H owner can keep on the shelf.

Main Features and Advantages
The delivers its value not through complexity but through absolute reliability in the harshest of industrial conditions. As the main AC fan assembly for the PowerFlex 700S/H platform, the is engineered to move a precisely calculated volume of air across the drive’s heatsink fins, extracting the tens of kilowatts of thermal energy generated by the IGBT modules during full-load operation. The 230-watt motor at the heart of the is sized to deliver this airflow continuously, 24 hours a day, 365 days a year, for the multi-year service interval expected of a large-frame VFD cooling component.
Perfect OEM fit and compatibility:
Because the is the exact fan assembly specified by Rockwell Automation for PowerFlex 700H and 700S drives, every mechanical dimension, mounting hole pattern, electrical connector, and airflow curve matches the original component. This guarantees that the replacement drops into the existing fan bracket without modification, mates with the existing wiring harness, and delivers the same cooling performance the drive was originally designed for. The alternative—installing a generic third-party fan—risks reduced airflow, connector incompatibility, or structural interference that can leave the drive under-cooled and vulnerable to thermal trips.
Protection of critical power electronics:
The IGBT modules inside a PowerFlex 700S/H drive are extraordinarily sensitive to temperature. Each 10 °C reduction in operating junction temperature roughly doubles the expected service life of the semiconductor. By ensuring that a healthy is always in place, plant engineers directly extend the lifespan of their IGBTs, diodes, and DC bus capacitors—components whose failure can cost tens of thousands of dollars in replacement and downtime. The is thus an inexpensive insurance policy against catastrophic power structure failure.
Preventive maintenance enablement:
Large-frame VFDs such as the PowerFlex 700S/H are typically installed in mission-critical applications—pipeline pumping, compressor drives, extruders, rolling mills, marine propulsion—where unplanned downtime carries enormous financial penalties. The is designed to be replaced as a planned maintenance activity: a spare is kept on the shelf, and during a scheduled shutdown the aging fan is swapped for a fresh , restoring full cooling capacity and resetting the maintenance clock. This proactive approach eliminates the majority of heat-related drive failures and transforms an unpredictable breakdown risk into a routine, low-cost procedure.
Safety and serviceability:
Rockwell’s official PowerFlex 700H/700S documentation provides explicit, step-by-step procedures for removing and installing the , reflecting the company’s commitment to field serviceability. When the proper lockout/tagout, bus discharge verification, and ESD precautions are followed, the can be replaced quickly and safely by qualified personnel. This transparency—documented in the PFLEX-IN029B-EN-P manual—distinguishes the from sealed, proprietary cooling solutions that trap owners in expensive service contracts.
