Air sander vs electric sander

Updated: 21 October 2026

You searched for an orbital sander and amazon.co.uk returned a 240 V DeWalt, an 18 V DeWalt, and a pneumatic palm in the same row of results. The names look alike. The workshop they belong in does not. This air sander vs electric sander page is the decision before the [air orbital sander comparison](/hub/sanders/air-orbital-sander): buy air when the workshop already has enough free air delivery, and buy electric when it does not. Electric models are not scored here. The Products Compared editorial team checked the amazon.co.uk listings on 19 October 2026 and did not run a lab test.

When an electric random orbit sander is the better buy

An electric random orbit sander is the better buy when you sand at weekends and you do not already own a compressor that can feed a continuous tool. A mains machine wants a 230 V socket and a BS 1363 plug. An 18 V machine wants a battery you already keep charged. For a table top, a door in a spare room, or furniture you can carry to a socket, that is the whole power question. The Proster prints Corded Electric on the specification line and pneumatic everywhere else. A true corded sander will show watts or volts and a plug, not a 1/4 inch inlet and a pressure in MPa. The buying guide is the air-side order of pad and orbit. Metro Sales, writing as a seller of air tools, says the compressor is the real cost. The Anesty at £27.90 is not cheaper than a capable corded sander once that compressor has to hold 90 psi.

When a pneumatic palm is the better buy

A pneumatic palm earns the hose when the airline is already on the wall and the session is long enough that a motor in your hand matters. Uneeda, an abrasives seller, says air is the compact tool at about 90 psi and electric is the choice away from a fixed airline. In a bodyshop that already sprays, the limit is free air delivery at about 90 psi. Short runs are what UK reviewers describe when the supply is small: the RUNQIN fading after about a minute and a half, the Draper managing only brief spells on a compressor the buyer rates at 5 cfm at 90 psi. Sizing that supply is the compressor for an air sander page. Setup, oil and the stroke are on how to use an air orbital sander, and they only apply after this choice.

Weight in this set

Air is not always lighter. In this set the Ingersoll Rand 4151-HL and 4152-HL are listed at 870 g, the SPTA mini at 780 g, the Draper 65084 at 1.17 kg, the Proster at 1.3 kg, and the Anesty at 1.48 kg. The Anesty is the counter-example to any sentence that says a pneumatic palm is automatically the light one. The SPTA mini is light because the pad is 25 to 80 mm.

Heat, noise and the choice

A vane motor does not have the brushed armature that gets hot on a long corded spell, which is why bodyshops stay on air. A motor that needs oil runs hot and sticks if you run it dry. The 4152-HL title says lube-free, so do not oil it. The Control of Noise at Work Regulations 2005 put the lower action value at 80 dB(A) and the upper at 85 dB(A). Ingersoll Rand prints 81.6 dBA for this family, which is not a measurement of the Anesty, the Draper or the SPTA kits. If you have no compressor that can hold a continuous tool at about 90 psi, buy electric. If the workshop air already keeps up, pick by pad and orbit.

Common questions

I sand at weekends and have no compressor. Which way do I go?
Buy an electric random orbit sander, mains or 18 V, and do not start with a pneumatic palm. Every tool kept in the air comparison needs compressed air. The cheapest air listing is still the expensive route once a compressor is in the basket. Weekend furniture near a socket is the job electric is for.
I already run air tools. When does a pneumatic palm earn its hose?
When the compressor’s free air delivery holds about 90 psi while the pad is on the work, and the session is long enough that a cool, compact palm matters. A nailer compressor that recovers between shots can still leave a sander fading after a minute. If your existing tools are intermittent, check delivery before you add a dual-action palm.
Are air sanders quieter?
Not as a rule. Ingersoll Rand publishes 81.6 dBA for its 4151/4152 family, which sits above the 80 dB(A) lower action value, and that number is not the budget palms. UK reviews call the mini kits noisy. Electric sanders are not silent either. Defenders are the sensible default for a long spell on either power source.
Are they always lighter?
No. The Anesty in this set is listed at 1.48 kg, heavier than the Ingersoll Rand palms at 870 g and heavier than plenty of compact electric sanders once you look at a specific model. The SPTA mini at 780 g is light because the pad is 25 to 80 mm, not because air is a weight class. Read the kilogram for the tool in your hand.
Can I carry an air sander to a job with a small compressor?
You can carry the kit, and the sander will still stop when the tank pressure falls. Reviewers describe fades of about a minute and a half and short runs on supplies around 5 cfm at 90 psi. An 18 V sander and a spare battery travel as one box.
Will an air tool overheat the way a brushed electric motor can?
A vane motor does not carry a brushed armature, which is why long bodyshop sessions stay on air. It can still run hot and stick if it is a motor that needs oil and you run it dry. The 4152-HL is titled lube-free, so that one is not an invitation to add oil.
