The best silent compressors, compared.
Top pick: Hyundai HY7524X 24 litre – Highest score: 24 litres that match the title, 1,072 reviews, and a dealer sheet that splits displacement from free air delivery. Best value: Hyundai HY5508X 8 litre – Cheapest listing that prints a decibel, agrees on tank size, states a UK plug, and has at least 100 reviews. Updated 20 October 2026.
You separate the machines by receiver litres, whether airflow is displacement or free air delivery, the maximum pressure, and whether the decibel line is sound pressure or sound power. Catalogue cells disagree, so this page shows the conflict. Litres, airflow and the plug are set out in the [silent compressor buying guide](/hub/compressors/silent-compressor/sub/silent-compressor-buying-guide). The jobs on those pages are a garage, a home workshop, nailers, tyres and light spraying. Handheld tyre inflators are a different product and are not in the set. They are not belt-drive workshop compressors and not cordless tyre pumps. A silent compressor, in the UK listings, is a corded electric air compressor with a receiver, an oil-free pump and a low-noise claim.

Question 1 of 2
What job is this for?
Across 1,072 amazon.co.uk reviews rated 4.6, the Hyundai HY7524X is the £149.95 oil-free 24 litre compressor UK reviewers use for hobby woodturning, spraying, nailers, and tyres after moving off a noisier oil-filled machine. The listing states 750 W, 230 V, 22 kg, 8 bar in the table, and 60 decibels, with wheels, a handle, twin gauges, and Euro connectors in the bullets, plus a 2-year warranty. The bullets print 5.2 CFM and 150 litres a minute; the table prints 2.65 CFM. A UK dealer sheet for this model treats 5.2 CFM as displacement and 2.65 CFM as free air delivery, and it places the 60 dB figure at 7 metres, which the amazon table does not say. One reviewer put working pressure near 100 psi and wanted more for a brad nailer. Repeated notes are a thread leak fixed with PTFE tape, a damaged gauge replaced by the seller, and steel shot in a new tank that rattled until it was drained. You get the longest UK review record here, and you still have two airflow numbers on one page.
Pros
Cons
Best for: You want 24 litres and the longest UK review record here for nailers, tyres, and light spraying.
Less suitable: You need a single airflow figure on the amazon page, or a brad nailer that must run above the pressure reviewers observed.
Specifications
Common questions
Does it need an oil change?
The bullets describe an oil-free pump and say oil checks are not required.
Which airflow number is on the listing?
The bullets say 5.2 CFM and 150 litres per minute. The air-flow cell says 2.65 cubic feet per minute.
What connectors does the title name?
Euro quick connectors, plus twin gauges in the title. A review says to check that those match the fittings you already own.
Across 989 amazon.co.uk reviews rated 4.5, the Hyundai HY5508X is the £129.99 oil-free 8 litre machine UK reviewers use indoors for an upholstery stapler, brads, and finish work. The table says 550 W, 100 psi, 60 decibels, 15 kg, and 230 V, and the bullets add a 13 A UK plug, Euro quick-release connectors, and a 2-year warranty. The airflow cell says 2 cubic centimetres a minute, which is not a usable compressor figure, while the bullets say 4 CFM and 120 litres a minute. Reviewers say the box has no hose and no tyre attachments, and one buyer budgeted about £25 extra. A regulator layout that did not suit airbrushing without another fitting also comes up. You get the second-largest review count in this set, and you still do not get one airflow number or a distance on the 60 decibel line.
Pros
Cons
Best for: You want indoor brads or an upholstery stapler, a stated 13 A plug, and a large review count.
Less suitable: You need a hose in the box, one usable airflow figure, or pressure above 100 psi.
Specifications
Common questions
What is the tank capacity?
8 litres in the title and in the tank-volume cell.
Does the box include a hose for tyres?
The included-components field says air compressor. A UK review says there is no hose and no tyre attachments, and that an extra fitting was needed for pressure control.
What noise figure is printed?
The sound-level cell says 60 decibels. It does not state a distance or LpA versus LwA.
The HYCHIKA 880W-24L is an oil-free 24 litre, 230 V compressor at £124.84, rated 4.5 from 27 amazon.co.uk reviews. UK reviewers have used it for a small spray gun, car valeting, and quieter running next to an older compressor, and one box included an extra spray nozzle. The same thin sample says the pump gets hot in heavy use, fills more slowly than the buyer expected, and, in one day-one report, smoked with a burning smell. The table says 62 decibels and 60 litres a minute; a bullet says 68 dB and 160 litres a minute intake. Weight is 21.8 kg in the table and 16.7 kg in a bullet, and the model number is 880W while the bullets say 1,100 W max. With 27 ratings, that smoke report is one review, not a failure rate, and it is still too small a pile to prefer this page over a listing whose cells agree.
Pros
Cons
Best for: You already accept a 27-review sample and you will not treat 160 litres a minute intake as free air.
Less suitable: You want specification cells that agree, or a day-one smoke report in a small sample is enough to put you off.
Specifications
Common questions
Which noise figure is on the listing?
The specification table says 62 decibels. A bullet says 68 dB. Neither states a distance or whether the figure is sound pressure or sound power.
Can the title’s uses be read off the box list?
The title names spraying, an air nailer, and tyre inflation. Included components are only the line “Air compressors”. One review mentions an extra spray nozzle.
How much does it weigh?
The item-weight cell says 21.8 kg. A bullet says 16.7 kg and describes two wheels and two handles.
Across 334 amazon.co.uk reviews rated 4.4, the ORAZIO 241183 is the £95.99 oil-free portable that UK reviewers use for light spraying and as a quieter stand-in for an old hardware-store compressor. The title and the capacity cell say 9 litres, 550 W, and 116 psi, while the tank-volume cell says 45 litres, so you cannot treat the receiver size as settled. Bullets print 65 dB(A) and 73 litres a minute, and the voltage cell says 220 V. Reviewers report leaks at fittings on arrival, a cut-out nearer 7 bar than the 8 bar they expected, metal debris in the tank, and a manual that asks for Teflon piston rings every six months when spares were not available. It is quieter than a common DIY compressor in those reviews, and it is not silent in a house at night. The included line is a filter, not a hose.
Pros
Cons
Best for: You want the lowest price here for light spraying and you will read the tank plate before you trust 9 litres.
Less suitable: You need a settled receiver size, a stated UK plug, or night-time use in a shared house.
Specifications
Common questions
Is the tank 9 litres or 45 litres?
The title and the capacity cell say 9 litres. The tank-volume cell says 45 litres. The listing does not resolve that.
Does it need oil?
The bullets say it is oil-free and needs no daily maintenance. A review says the manual asks for Teflon piston rings every six months and that spares were not available.
What voltage does the table show?
The voltage cell says 220 volts. UK mains are not restated on the listing.
The ABAC Ease-AIR 6 is a 6 litre, 8 bar, 0.75 hp, 230 V oil-free compressor at £155.99 and 15.3 kg, rated 4.4 from 291 amazon.co.uk reviews. The table says 49 decibels and the bullets say 49 dBA, with airflow of 110 litres a minute described as aspirated air. Included parts are a Type G UK adaptor and a user manual, not a moulded BS 1363 plug named on the cord. The review texts saved with that file are from outside the United Kingdom, so the star count is not a UK narrative. Those reviews praise a fast fill of the small tank and use on nailers, tyres, and blowing, and they say a 6 litre receiver cycles often. A Belgian reviewer writes that the advert says 49 dB(A) while the machine is marked 67 dB Lwa. You pay the most in this set for the lowest printed decibel and the smallest tank, and you still have to check the adaptor and the sound-power mark on arrival.
Pros
Cons
Best for: You want the only 49 dB line in this set for a small indoor tank and you will check the adaptor and any Lwa mark.
Less suitable: You need a UK review narrative, a 24 litre receiver, or a moulded plug named in the box list.
Specifications
Common questions
What noise figure does the amazon.co.uk listing print?
49 decibels in the table and 49 dBA in the bullets. Reviews saved with the saved listing, from outside the United Kingdom, say the machine is marked 67 dB Lwa.
What plug parts are listed?
Included components are a Type G (UK) adaptor and a user manual. A moulded BS 1363 plug is not named.
How big is the tank?
6 litres, maximum pressure 8 bar, weight 15.3 kg.
The Bimson Power AC-230V-1450-24L is a 24 litre, 750 W, 230 V oil-free compressor at £114.99 and 22 kg, rated 4.4 from 51 amazon.co.uk reviews. UK reviewers have used it on finishing nailers and on a first-fix framing nailer with 90 mm nails for garden work, and one said a spray gun seemed to have air while the tank was filling. The same file says it is not the machine for painting a car. The listing calls it quiet and low-noise and prints neither a decibel nor an airflow figure, so you cannot compare it with a 60 dB line on another page. Faults in that small sample include a unit that would not start after months of little use, and a fitting leak that emptied the tank. Included components are a user manual. The item highlight states a 2-year warranty.
Pros
Cons
Best for: You want 24 litres at the lower price for intermittent nailers and you can buy without a printed decibel.
Less suitable: You need a CFM or a decibel you can compare, or you are painting a car.
Specifications
Common questions
How many decibels does the listing state?
None. The bullets and the item highlight say low noise or quiet, and the specification table has no sound-level cell.
Are tyre attachments included?
Included components are a user manual. A hose, a chuck, and couplers are not listed. The listing asks whether it can inflate tyres and does not answer that in the table.
What pressure and tank does it list?
24 litres and 116 psi, at 750 W and 230 V, oil-free, 22 kg.
For this comparison we read six silent-compressor listings on amazon.co.uk, shelf date 19 October 2026, plus the review patterns recorded for those ASINs and the Metro Sales sheet for the Hyundai HY7524X where it separates displacement from free air delivery. Scores use the weights below. This is not a laboratory test. A bare decibel is not an LpA, and a quiet title with no number is not a measurement.
Amazon evidence
30%Star points use the listing average above 4.0, capped, plus a step for review volume. Under 30 reviews the volume step adds nothing. The two parts together cannot exceed 30.
Listing clarity
40%Tank litres that agree with the title, a readable noise figure, one airflow figure, a stated pressure, oil-free, and 230 V with a named UK plug score higher. A second tank figure, conflicting decibels, an unusable airflow cell, or a Type G adaptor without a moulded plug score lower.
Review outcome
15%A large UK-dated file that names a job and a limit scores higher. A thin file, a day-one smoke report, or saved review text that is not from the United Kingdom scores lower. One defect report is not a failure rate.
Value
15%Shelf price in GBP is set against a receiver you can identify. The lowest price does not win when the tank cell contradicts the title, and a missing decibel costs points in a category sold as silent.
Choose the air the tool needs, then the receiver, then a decibel line you can interpret. A quiet title is not a measurement, and the shelf price does not include a hose.
A silent compressor, in the UK listings kept for this comparison, is a corded electric air compressor with a receiver, an oil-free pump and a low-noise claim. The jobs on those pages are a garage, a home workshop, nailers, tyres and light spraying. Handheld tyre inflators are a different product and are not in the set. The machines here are oil-free direct-drive portables. They are not belt-drive workshop compressors and not cordless tyre pumps.
ABAC’s 49 dB line, the Hyundai 60 dB cells, ORAZIO’s 65 dB(A) and HYCHIKA’s 62 dB and 68 dB are not one measurement. A non-UK review says the ABAC machine is marked 67 dB Lwa. A SIP page prints both LpA and LwA for one 24 litre model. A quiet title with no number, as on the Bimson listing, is not a result.
The Hyundai 24 litre bullets say 5.2 CFM. The table says 2.65 CFM. A dealer sheet splits those into displacement and free air delivery. The Hyundai 8 litre table cell says 2 cubic centimetres a minute against a 4 CFM bullet. HYCHIKA’s 160 L/min intake is not the 60 L/min table cell. Use the free-air figure you can identify.
Several boxes list the compressor and a manual, not a hose or a tyre kit. A Euro coupler may not match the fittings you own. Oil-free means no oil checks on these pages. It does not mean the air is dry or breathable. Drain the tank, and call a professional if the safety valve, tank or switch is damaged, or if the pump smoked.
Match free air delivery, not the horsepower or wattage line. On these pages the two numbers often disagree, and the disagreement is the fact you buy with. The Hyundai HY7524X bullets say 5.2 CFM and 150 litres a minute. The table says 2.65 CFM. A UK dealer sheet for the same model treats 5.2 CFM as displacement and 2.65 CFM as free air delivery. Amazon still prints both, so do not pick the larger bullet as the air a nailer will see. The Hyundai HY5508X bullets say 4 CFM and 120 litres a minute.
A bare decibel is not a sound-pressure level, and a quiet title with no number is not a measurement. ABAC prints 49 dB and 49 dBA. Both Hyundais print 60 dB, with no distance on the amazon table. A dealer sheet for the Hyundai 24 litre places that 60 dB at 7 metres, which the amazon cell does not say. ORAZIO prints 65 dB(A). HYCHIKA prints 62 dB in the table and 68 dB in a bullet. Bimson prints none.
Three typical situations, each with a recommendation from this comparison.
You want a garage or indoor machine for brads, staples, tyres and light spraying, with a 24 litre receiver and the longest UK review record in this set. The Hyundai HY7524X is the top pick at about £149.95, 4.6 from 1,072 reviews. Amazon still prints two airflow figures.
You care whether a small tank restarts every few shots. The Hyundai HY5508X is the 8 litre best value at about £129.99, with a stated 13 A UK plug and 4.5 from 989 reviews. UK reviews say the box has no hose.
You want the only 49 dB line in this set, on a 6 litre tank at about £155.99. The ABAC Ease-AIR 6 lists a Type G adaptor, not a moulded plug. Saved review texts are not from the United Kingdom, and one cites 67 dB Lwa on the machine.
The Hyundai HY7524X is the top pick because it is the highest score: a 24 litre receiver that matches the title, 4.6 from 1,072 amazon.co.uk reviews, and a dealer sheet that explains the two airflow cells. The Hyundai HY5508X is the best value at about £129.99 because it is the cheapest listing that prints a decibel, agrees on tank size, states a 13 A UK plug, and has 989 reviews. The ORAZIO is cheaper, and the 9 litre / 45 litre conflict keeps it off that rule. The Bimson is cheaper per litre, and it prints no decibel.
Hyundai HY7524X 24 litre
Highest score: 24 litres that match the title, 1,072 reviews, and a dealer sheet that splits displacement from free air delivery.
Hyundai HY5508X 8 litre
Cheapest listing that prints a decibel, agrees on tank size, states a UK plug, and has at least 100 reviews.
