This is a direct-fit replacement propeller for 48" PolarCool evaporative cooling fans. If your fan's airflow has weakened or the current prop is cracked or unbalanced, this galvanized 3-blade unit restores performance without a full fan replacement.
The 6403-5014 is the current-production 48" propeller for PolarCool's evaporative cooling fan line. Galvanized construction resists the corrosion and wear typical of outdoor and warehouse cooling duty, where humidity and airborne debris shorten the life of lesser hardware. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fitment & Requirements
- Size: 48" diameter propeller, 3-blade configuration.
- Material: Galvanized construction.
- Fits all 48" PolarCool models, both 120V and 240V — specifically SKUs 6622-1300 and 6622-1310.
- NOT a drop-in replacement for red fiberglass propellers without additional parts — replacing a fiberglass prop requires a new shaft and shear keys (part numbers 0411-5626 or 0411-14099, verify by shaft dimensions).
- Not intended for fan models outside the 48" PolarCool 6622-1300 / 6622-1310 family — confirm shaft and housing dimensions before ordering for any other unit.
Key Benefits

- 3-blade design supports efficient, high-volume airflow for evaporative cooling.
- Direct-fit replacement for current 48" PolarCool models reduces service time.
- Works across both 120V and 240V fan variants, simplifying spare parts inventory.
- Genuine PolarCool component built for durability and reliable cooling performance.
