Air blow gun vs electric duster
Updated: 21.10.2026
Amazon.co.uk hands you two tools under one phrase: a pistol for a compressor hose, and a cordless fan sold as an air duster. An air blow gun vs electric duster choice is whether you already own a tank. If you do, and the job is loose workshop dust, the pneumatic pistol is the tool. If you do not, or the job is a keyboard, a PC or a camera, buy a duster or a can. The [compressed air gun comparison](/hub/compressors/compressed-air-gun) keeps only blow guns. Electric dusters were removed from that set. We did not run a side-by-side lab test. A qualifying purchase can earn a commission at no extra cost to you.

Two tools, one search
A pneumatic blow gun is a trigger and a nozzle on a compressor hose. It moves air that a receiver has already stored. An electric duster is a small fan, cordless or on a mains lead, and it does not care whether you own a tank. A propellant can is a third thing: a sealed charge of gas, often butane, that is empty when the can is empty. The same amazon.co.uk words, compressed air and air duster, cover all three, which is why cordless blowers were deleted from this comparison before any score was written.
Dust on a lathe bed, dust in a keyboard, and dust on a sensor are three decisions. A pistol at workshop pressure is a blunt instrument on a camera. Brand pages quote motor speeds such as 110,000 rpm. Those are manufacturer claims, not a test. Name the tool by the energy source before you compare prices.
Keyboard, camera and car interior
Send a keyboard, a PC and a camera to a duster or a can. HomeOwnersHub's practical note is that cans suit a camera because the gas is dry, while a compressor jet can be too hard and can carry whatever is in the tank. Keep a butane can nearly upright. Winstanley's band for those cans is about £5 to £20, and a tipped can spits cold liquid onto the board you were trying to clear. That liquid is the failure mode, not a stronger clean.
Do not offer the MEANLIN ten-pack, or any of the kept pistols, as more air for electronics. None of the three states litres per minute. A UK review called the ABAC nozzle air-hungry, which means a wide blast and a small tank, not a gentle puff for a keyboard. Car interiors and car drying sit in the same refusal. If the machine plugs into a USB charger or a 13 A socket and has no hose, you are in duster territory even if the box says compressed air.
Bench dust and swarf
The compressor gun wins only when the tank, the regulator and a matching plug already exist. A home garage with a 6 to 50 litre compressor can run one pistol for loose chips a brush has lifted, with eye protection, at an exit pressure cut towards the HSE guide of about 2.1 bar. That is the job. It is not a reason to blow coolant and swarf into the air, and it is not a reason to assume the air is dry. A tank holds water. An oiled compressor can carry oil mist. Both show up on the work if you blast a freshly painted panel or an open electrical board.
The plug still has to match. A £7 pistol on the wrong coupling does not become the right tool because you already paid for the compressor. PCL Standard and Euro do not interchange, and standard on a listing is not a family. The air blow gun buying guide is where that match is made. Until the sleeve locks, the comparison between a pistol and a duster is theoretical.
What you actually pay
£7 to £12 for a pistol is not the cost of compressed air. On the 19 October 2026 capture the ABAC G-503 is £7.37 and the oumuik OD-1 is £7.99. The MEANLIN ten-pack is £31.99. You only reach those prices if the compressor is already in the garage. Buying a tank in order to save the cost of a duster is the expensive route, and this page will not add a compressor's price to a gun you do not need.
A can at £5 to £20 runs out. A cordless duster in the Wolfbox band sits around £30 to £40, and a mains example such as CompuCleaner is a 500 W fan. The pistol is the cheaper clean when you already have a tank and a hose that fits. The duster is the cheaper clean when you would otherwise buy the tank. The best air blow gun page is only for the compressor path.
Common questions
Is a cordless duster the same as a blow gun?
No. A blow gun needs a compressor. A cordless duster is a fan with a battery. Listings mix the names, which is why electric dusters were taken out of this set before scoring. Motor-speed claims, including figures around 110,000 rpm, are brand statements. They are not a test against the pistols, and the pistols do not publish litres per minute for you to compare.
Are compressed-air cans safer for a camera?
They are the usual choice when you want dry gas and a small puff, which is the HomeOwnersHub point, as long as the can stays nearly upright. A tipped can spits cold propellant. A compressor jet can be too hard and can carry water or oil mist from the tank. Safer here means the right dose for a sensor.
Can the £7 ABAC dry a car or clean a PC?
Do not buy it for either job. It is £7.37 on the capture, with a UK review that called the nozzle air-hungry, and the listing does not state litres per minute. A PC wants a duster or a can. A wet car wants a towel or a blower designed for that work, not a workshop pistol on a 6 to 50 litre tank. The ABAC remains a cheap gun for loose garage dust only if the plug fits.
Which is cheaper over a year?
If you already own the compressor and the plug matches, the pistol at about £7 to £12 is the small extra cost, and the air is a running cost you already pay. If you do not own a compressor, a can at £5 to £20 each, or a cordless duster around £30 to £40, is cheaper than buying a tank to feed a gun. The MEANLIN pack at £31.99 does not change that split. It is still a compressor tool.
Will compressor air put water or oil on electronics?
It can. A receiver collects water, and an oiled compressor can put oil mist into the hose. That is a reason to keep workshop pistols off open boards and cameras. Cans are used for those jobs because the charge is dry, provided you do not invert them. Nothing in the three kept listings says the outlet air is filtered or dried.
What if I already own a 24 litre compressor?
Then a pneumatic pistol is the coherent buy for loose bench dust, after you match the plug and set a low exit pressure. One UK review of the ABAC mentions a Parkside PKO270 A2 24 litre hose, which is an anecdote about fit, not a promise for every 24 litre set. Keyboards and cameras still go to a duster. The buying guide is the next page if the socket family is unclear.
