Pneumatic Versus Electric Random Orbital Sanders

Pneumatic Versus Electric Random Orbital Sanders


Are you in the market for a new random orbital sander and wondering whether to go with the electric or pneumatic? This article covers various aspects to consider in making this decision, beyond simply the cost of the units, including the technical aspects and how and where you’ll be using the sander(s).

Uneeda’s orbital sanders are all a similar style, featuring an ergonomic, symmetrical, lightweight body with a lever on the top to activate the sander. Both styles come with the option of 3/16” or 3/32” orbits and are available in 3”, 5”, 6” and 3×4” formats with and without dust extraction options. The electric sander has an elongated handle on the back, which contains all the electrical components. The pneumatic sanders do not have this handle and are therefore smaller/lighter.

Uneeda’s pneumatic sanders are built with an aluminum housing for durability and to help the unit be more lightweight and absorb vibration. They require 90 PSI of air to run smoothly. The 5 and 6” units run at 12,000 RPM and the 3×4 option runs optimally at 10,000 RPM.

Uneeda’s electric sanders have a brushless and DC driven motor. They contain internal fans to reduce heat on the center nut, thus helping the unit run cooler internally and reducing problems that would occur from heat. They have four adjustable speeds, from 8000 to 12,000 RPM and have a system to protect against overheating.

Regardless of whether you choose air or electric, all the round units – 3”, 5” and 6” – offer a random orbit pattern, and the rectangular units have a “fixed” orbit pattern. The benefit of the random pattern is that it makes it more difficult to observe the sanding pattern on the sanded surface and in the finish, whereas with a fixed rotation, it is more likely to see sanding swirls and other issues. When using the 3×4, this can be reduced by using a pad saver on your backup pad. Swirls and evidence of orbital sanding can be removed or reduced by running the sander at proper speeds/psi for air sanders, and sanding with a non-woven product prior to finishing.
