The Husqvarna 516057301 Fan is a genuine OEM replacement designed for PG680, PG820, PG680RC, and PG820RC floor grinders. As a direct Husqvarna OEM component, this fan is manufactured to the exact specifications required to maintain correct airflow and cooling performance in these machines. It is a direct drop-in replacement that restores proper thermal management to your grinder, keeping it operating within safe temperature limits during demanding surface preparation work. DHS Equipment supplies this part to help keep your floor grinding equipment running at full capacity.
Key Features
- Genuine OEM Airflow Specification — manufactured to Husqvarna's exact blade pitch, diameter, and rotational balance tolerances, ensuring the correct volume of air moves through the motor housing on every pass.
- Direct-Fit Replacement — engineered to match the original mounting interface on PG680, PG820, PG680RC, and PG820RC floor grinders, allowing straightforward installation against the existing motor shaft and housing.
- Compatible with PG680 and PG820 Series — covers both the standard and remote-control variants (PG680, PG680RC, PG820, PG820RC), making this a versatile part across Husqvarna's mid-to-large planetary floor grinder range.
- Sustained Motor Temperature Control — a properly functioning fan draws heat away from the drive motor during extended grinding sessions, protecting windings and bearings from heat-related wear and premature failure.
- Thermal Safety Compliance — maintaining the correct cooling fan ensures the machine operates within its designed thermal envelope, reducing the risk of motor overheating and unexpected shutdown during continuous-duty floor grinding operations.
The fan in a floor grinder serves as the primary cooling component for the drive motor, drawing ambient air through the motor housing to dissipate heat generated during operation. On planetary grinders like the PG680 and PG820 series, the motor works under sustained load, making consistent airflow critical to long-term performance. A damaged or missing fan can allow motor temperatures to climb beyond safe limits, leading to insulation breakdown, bearing failure, or automatic thermal cutout — any of which will halt production on the floor.
