Indasa Random Orbital Sanders: How to Choose Orbit, Vacuum and Electric vs Air
Choosing an Indasa random orbital sander on Manu is a three-part match: power (corded electric vs air), orbit (3/32" finishing vs 3/16" cutting), and how dust leaves the pad (self-generating bag, 29 mm hose to an extractor, or no vacuum). Every tool below is a current Indasa listing in the paint and body-shop supplies collection. Part numbers in parentheses are from the product titles.
Pick the orbit and pad first
The Indasa pages state the orbits in both inches and millimeters: 3/32" (2.5 mm) is the finishing orbit, and 3/16" (5 mm) is the faster-cutting orbit. Several electric listings say this outright — for example, the 6" 3/32" sander 579558 tells you to choose 579541 when you want the 3/16" cut. Use 3/32" for final prep and denibbing; use 3/16" for stripping and shaping filler or primer.
Pad diameter is the other size on the label:
- 3" — spot, rim and tight areas (air tools only in this assortment)
- 5" — general panels; the electric finishing kit includes a 5" 5-hole grip pad
- 6" — larger panels, fewer passes
Electric sanders when you do not have shop air
These are corded E-Series tools. The listings emphasize that they do not need a compressor and that the vacuum-ready models use a 29 mm hose, the same size named on the LPE45 extractor.
| Part no. | Pad | Orbit | Notes from the listing | Price |
|---|---|---|---|---|
| 596412 | 5" | 3/32" (2.5 mm) | Finishing kit; 5" 5-hole grip pad included; vacuum-ready | $722.43 |
| 579558 | 6" | 3/32" (2.5 mm) | Vacuum-ready; sized for larger panels | $689.08 |
| 579541 | 6" | 3/16" (5 mm) | Vacuum-ready; faster cut than 579558 | $678.38 |
| 579565 | 5" | 3/16" (5 mm) | Vacuum-ready; 3/16" cut on a 5" pad | $675.17 |
If you are finishing clear and have no compressor, 596412 (5") or 579558 (6") is the direct match. If you are cutting through primer on large panels and still want electric power, 579541 is the 6" 3/16" option.
Air DA sanders: self-generating, central-vacuum, or non-vacuum
Self-generating vacuum (SGV) tools make their own suction and dump dust into an attached bag — no extractor required. Central-vacuum-ready tools hook to a portable or central extractor (pair them with the LPE45). Non-vacuum tools are lighter and cheaper; they throw dust unless you have another capture method.
| Part no. | Pad | Orbit | Dust collection | Price |
|---|---|---|---|---|
| 3DAVSAND | 3" | 3/32" | Self-generating bag | $381.46 |
| 5DAVSAND | 5" | 3/16" | Self-generating bag | $370.95 |
| 5-32DAVSAND | 5" | 3/32" | Self-generating bag | $370.95 |
| 6-32DAVSAND | 6" | 3/32" | Self-generating bag | $370.95 |
| 6-32DASAND | 6" | 3/32" | Self-generating bag. This is a second 6" SGV 3/32" listing at a lower price; order by the part number, not the title alone | $346.68 |
| 5DACVSAND | 5" | 3/16" | Central-vacuum ready | $345.19 |
| 3DACVSAND | 3" | 3/16" | Central-vacuum ready | $339.19 |
| 6DASAND | 6" | 3/16" | Non-vacuum; variable speed | $328.49 |
| 6DACVSAND | 6" | 3/16" | Central-vacuum ready | $322.61 |
| 526934 | 6" | 3/32" | Central-vacuum ready | $322.61 |
| 3DASAND | 3" | 3/16" | Non-vacuum | $291.95 |
| 5DASAND | 5" | 3/16" | Non-vacuum | $286.76 |
| 5-32DASAND | 5" | 3/32" | Non-vacuum | $286.76 |
A practical shop kit is one 5" or 6" 3/16" sander for cutting and one 3/32" sander for finishing. If you already run a 29 mm extractor, prefer the central-vacuum-ready SKUs (5DACVSAND, 6DACVSAND, 526934, 3DACVSAND). If you work away from the extractor, the SGV bag tools (5DAVSAND, 5-32DAVSAND, 3DAVSAND) are the cleaner air option.
Dust extractors that match the 29 mm tools
The Indasa LPE45 (592526) ($1,431.11) is a 9.25-gallon (35 L) mobile extractor with auto tool-start. The page says it pairs with vacuum-ready air and electric Indasa sanders on a 29 mm hose, and that it uses fleece filter bags. The Workstation Pro (593110) ($1,076.19) packages LPE45-style extraction with hose management and a work surface on one rolling station. Choose the Workstation Pro when you want the extractor and a rolling bench together; choose the standalone LPE45 when you already have a cart.
Rebuild kits instead of a new air sander
For worn pneumatic tools, Manu lists two overhaul kits: DA-REPAIR-5/6 (AVA0852) ($68.48) for Indasa 5" and 6" air DA sanders, and DA-REPAIR-3 ($50.29) for the 3" air DA sanders. They are not for the corded electric models. Disconnect the air line and follow the kit’s parts list; do not mix the 3" kit with a 5" or 6" motor.
Safety
Sanding body filler, paint and primer creates dust you should not breathe. Use the extractor or SGV bag that matches the tool, and wear appropriate eye, hearing and respiratory protection for the material you are cutting. Air sanders are pneumatic tools: confirm a clean, regulated air supply, and bleed the line before you change pads or open the motor. Electric sanders are corded — keep the cord off the abrasive and off wet floors. Never collect sparks or solvent-soaked debris in a dust bag, and empty fleece bags before they cake the filter.
FAQ
Do I need a compressor for Indasa electric sanders?
No. The E-Series listings (596412, 579558, 579541, 579565) are corded electric and are sold specifically for shops without a compressor. You will still want the LPE45 or another 29 mm extractor if you want dust capture.
What is the difference between 3/32" and 3/16" orbits?
On these pages, 3/32" (2.5 mm) is the finishing orbit and 3/16" (5 mm) is the faster-cutting orbit. That is a scratch-pattern choice, not a pad-size choice. You can order both orbits in 5" and 6" air or electric versions.
Why are there two 6" self-generating 3/32" sanders?
Manu currently lists both 6-32DAVSAND at $370.95 and 6-32DASAND at $346.68, with the same pad, orbit and SGV description. Order by the part number shown on the product page you want, and confirm the number on the box when it arrives.
