HOT ! Hawk F03-20-01 20-Inch 2-Speed Floor Machine – 1.5 HP DC, 175/320 RPM

Hawk F03-20-01 Heavy Duty 2-Speed Floor Machine – 175 and 320 RPM

The Hawk F03-20-01 runs a 1.5 HP DC rectified motor at 175 RPM for stripping and scrubbing, and at 320 RPM for spray buffing. The higher baseline speed of 175 RPM (versus the 165 RPM F04 series) produces slightly more aggressive pad action on hard floor finishes. At 97 lbs, the machine delivers consistent downward pressure through the 20-inch pad across both speed settings.

F03-20-01 Motor Torque, Speed Range, and Weight Distribution

• 
  Motor: 1.5 HP DC rectified — flat torque curve across 175 and 320 RPM prevents bogging under pad load on stripped or wet floors.


• 
  Low speed: 175 RPM at 60 dB — quieter than most comparable 165 RPM machines; strips and scrubs VCT, tile, and terrazzo without ear protection requirements.


• 
  High speed: 320 RPM at 69 dB — spray buffing speed for lobby corridors, gymnasiums, and high-traffic hallways requiring a maintained gloss finish.


• 
  Weight: 97 lbs — 3 lbs more than the F04-20-01; applies additional pad pressure on stripping passes with black pads.


• 
  Pad size: 20 inch — standard 20-inch rotary pads across full aggression range.

Heavy Duty Applications for the F03-20-01

The F03-20-01 targets facilities with high floor care frequency—schools, hospitals, airports, and large retail environments that strip and refinish multiple times per year. At 175 RPM, the machine removes aged finish buildup on VCT more aggressively than a 165 RPM unit, reducing the number of stripping passes required on heavily coated floors. The 320 RPM spray buffing speed produces a wet-look gloss on low-maintenance finish systems without a separate burnisher. Janitorial contractors running a single machine between stripping and buffing cycles get the most value from the F03\'s speed range.

DC Motor Performance at Sustained Load

DC rectified motors hold their rated RPM under sustained pad resistance better than single-phase AC motors of the same HP rating. On floors with multiple layers of aged finish, pad resistance peaks during the first stripping pass. The F03-20-01\'s DC motor compensates by drawing more current to maintain 175 RPM rather than slowing down—keeping the pad cutting consistently and reducing the risk of leaving unstripped patches. The motor runs cooler under these sustained loads, which extends pad driver life and reduces downtime between jobs.
