How the points were given
Each sander is scored out of 10 on performance, build, value, safety and warranty, with the weights published on our How We Pick page. None of the 5 listings states an electrical safety listing, so every sander scores zero on safety, which pulls all scores down.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| UPWOOD UW-942AB | 9.7 | 30 | 21 | 21 | n/a | 2 |
| Dynastus 033020 | 9.6 | 30 | 21 | 20 | n/a | 0 |
| BOWD AT-980 | 9.6 | 29 | 21 | 20 | n/a | 0 |
| UPWOOD 214-75NV | 9.6 | 29 | 20 | 20 | n/a | 0 |
| Eastwood Rockwood | 9.5 | 26 | 20 | 19 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

Buying guide: choosing the best air random orbital sander under 100
Pad size
Pad sizes run from 2 in and 3 in on the UPWOOD UW-942AB to 6 in on the Dynastus 033020 and the Eastwood Rockwood, with the BOWD AT-980 at 5 in and the UPWOOD 214-75NV at 3 in. A small pad fits tight areas and edges, while a 6 in pad covers a panel faster.
Free speed and air use
Free speed runs from 10,500 RPM on the Dynastus 033020 and the Eastwood Rockwood to 15,000 RPM on the UPWOOD UW-942AB, with the BOWD AT-980 and the UPWOOD 214-75NV at 12,000 RPM. Air use is stated on only 2 listings: 4 CFM on the UPWOOD UW-942AB and 10.5 CFM on the UPWOOD 214-75NV. Check the compressor against the sander air use before the first job, since a sander that starves for air will not reach its free speed.
Orbit diameter and finish
Orbit diameter is stated on 2 listings: 3mm on the UPWOOD UW-942AB and 3/32 in, 2.5 mm, on the UPWOOD 214-75NV. A dual-action orbit helps reduce swirl marks, and the listings describe swirl-free finishes on the Dynastus 033020 and the UPWOOD UW-942AB.
Weight and noise
Weight runs from 1.5 lb on the UPWOOD UW-942AB to 2.1 lb on the Eastwood Rockwood, with the Dynastus 033020 at 1.85 lb and the BOWD AT-980 at 2 lb. The UPWOOD 214-75NV states 0.99 kg. Only the UPWOOD 214-75NV states a noise figure, 72 dB, and the Dynastus 033020 states internal silencing.
Pads, discs and what comes in the box
The UPWOOD UW-942AB includes 24 sanding discs, 12 in 2-inch and 12 in 3-inch, in 80 and 120 grits. The BOWD AT-980 includes 10 sandpapers in P240 grit, the Dynastus 033020 includes 10 sanding discs, and the UPWOOD 214-75NV includes 12 sandpapers plus an extra backing pad. The Eastwood Rockwood listing states a 22 mm flat wrench and a 1/4 in quick-disconnect inlet fitting.
Pick the air tools you run and get the CFM at 90 PSI and tank size to shop for.
Wear eye protection with every air tool, use impact-rated sockets on impact wrenches, disconnect the air line before changing accessories, and finish lug nuts with a torque wrench to the vehicle's spec. See OSHA eye and face protection. Read our Safety Disclaimer.
Garage Fit Check
- Check the compressor: the UPWOOD UW-942AB uses 4 CFM and the UPWOOD 214-75NV uses 10.5 CFM, both at 90 PSI, so match the sander to the compressor air delivery.
- Check the pad: 2 in and 3 in pads fit tight areas and edges, while the 6 in pads on the Dynastus 033020 and the Eastwood Rockwood suit panels.
- Check the fittings: the BOWD AT-980 includes a 1/4 in NPT air inlet connector, and the Eastwood Rockwood includes a 1/4 in MNPT quick-disconnect inlet fitting.
- Check the discs: the UPWOOD UW-942AB includes 24 discs, while the BOWD AT-980 and the Dynastus 033020 include 10 sandpapers each and the UPWOOD 214-75NV includes 12.
