Quiet 50 litre air compressor
Updated: 21.10.2026
A 62 dB badge on a 50 litre compressor looks like the answer if your garage sits under a bedroom or against a neighbour’s wall. It may be a sound-power figure, a sound-pressure figure, or a number with no method at all. This page is about a quiet 50 litre air compressor only in that sense: what the decibel titles in this amazon.co.uk set can and cannot mean, and what the Control of Noise at Work Regulations 2005 require when the machine is used at work. Airflow and tank size stay on the [50 litre air compressor buying guide](/hub/compressors/50l-air-compressor/sub/50l-air-compressor-buying-guide). The [50 L air compressor comparison](/hub/compressors/50l-air-compressor) is the listing table. We used those listings, Einhell UK, HSE’s NOMAD note and the regulations. We did not measure these machines.

Two different decibel numbers
Sound pressure, written Lp or LpA, is the level at a stated place, often at the operator. Sound power, written Lw or LwA, is the total sound the machine emits. HSE’s NOMAD note says those quantities are not interchangeable, and that sound power is often about 10–20 dB higher than the emission sound pressure for the same product. A title that prints one bare decibel number does not tell you which you are looking at, or at what distance.
Scheppach’s HC51Si page is the worked example, and that model is not one of the four listings in this set. It prints Lp(A) 60 dB beside a guaranteed sound power of 87 dB. Both numbers are real on that page. They describe different things. A shopper who compares 60 dB with another brand’s 87 dB is not comparing two compressors. They are comparing a pressure figure with a power figure. The same doubt applies to any 50 litre machine whose Amazon title says 62 dB and stops there.
Einhell shows the conflict inside one article
Amazon’s listing for the TC-AC 240/50/10 OF prints 95 dB. Einhell UK, for article 4010393, prints 77 dB(A) sound pressure. Those are not two measurements of the same quantity on the same page, and neither Amazon figure in this set states the test distance. BS EN ISO 2151:2008 is the noise test code for compressors. A listing that ignores the code does not become quiet because a retailer uses the word silent.
What these four listings allow you to say
Amazon states 95 dB for the Einhell and 97 dB for the ABAC Ease-AIR 50V. Neither line says sound pressure or sound power. In the review samples, buyers call both machines loud. Einhell UK reviews mention noise and vibration through the room when the tank refills. ABAC reviews call it very loud, in line with the 97 dB title. You can say the shoppers who wrote those reviews found them noisy. You cannot convert 95 dB on a title into minutes of legal exposure at your ear, because the listing does not show that 95 dB is the level where you stand.
Both SIP listings print 62 dB. Neither says LpA, LwA or a distance. The vertical model, part 05483, has three short UK reviews. They say it was quieter than a cheaper compressor the buyer returned, and they also say it is not quite silent. That is the whole performance limit those texts give you. The horizontal model, part 05479, has no review text, so 62 dB there is an untested title. You cannot compare that 62 with the ABAC’s 97 as if a lower integer were a quieter machine. One of them may be sound power and the other a pressure figure taken somewhere else. Until the unit and the distance are named, the gap is not evidence.
Retail pages often sort silent stock at about 60–70 dB and traditional direct-drive machines at about 90–100 dB. Those bands are a shop’s shorthand. They still collapse if the 60 and the 95 are different quantities. Quieter 50 litre models on UK brand shops in the same week, including Hyundai, Scheppach and an Einhell Silent Plus, sat around £299 to £359.95. That price band is context. It is not a test that those machines are quiet in your garage, and you still have to read free air delivery before you leave this set.

Home, neighbours and work
The Control of Noise at Work Regulations 2005 bind employers. They do not bind a householder using a compressor on a Sunday. Regulation 4 sets a lower exposure action value of 80 dB(A), an upper action value of 85 dB(A), and an exposure limit of 87 dB(A), assessed at the ear and allowing for hearing protection at the limit. Hearing protection should be available where daily exposure is likely to reach 80 dB(A). It is required, if the noise cannot be reduced by other means, where exposure is likely to reach 85 dB(A). Those are employer duties. They are not a fine for DIY.
Hearing risk does not stop because the regulations do not name you. A machine that reviewers call loud in a brick garage will be heard through a party wall, and it will be loud for whoever stands next to the pump while a nailer runs. HSE’s noise calculator is the tool for a measured level at the ear. It is not a way to turn Amazon’s 95 dB into your personal exposure time. Do not treat a third-party 15 minutes at 95 dB reckoning as your legal position unless someone has measured 95 dB(A) where you work.
If staff will use the compressor, the dutyholder assesses the real level, reduces it where practicable, and does not rely on a 62 dB title that lacks a method. A private garage can still choose a different machine because of neighbours. That choice is comfort and courtesy, plus whatever your household will tolerate, not regulation 4. How you start and stop the machine you do buy, including when to unplug a unit that will not cut out, is on the how to use a 50L air compressor page.
Common questions
Is 62 dB quiet enough for a terrace garage?
Not on the number alone. Both SIP listings print 62 dB without sound pressure, sound power or distance. The vertical model’s UK reviews say it is not quite silent. A terrace garage needs the quantity and the distance, then a judgement about the wall you share. A bare 62 is not a neighbour guarantee.
Why does Einhell UK say 77 dB(A) when Amazon says 95 dB?
Einhell UK states 77 dB(A) sound pressure for article 4010393. The amazon.co.uk listing prints 95 dB and does not name the quantity. They are not the same claim. Reviews still call that compressor loud, with vibration when the tank refills, so the lower manufacturer figure is not a promise that a UK garage will find it quiet.
Can I compare the SIP’s 62 dB with the ABAC’s 97 dB?
Not as a ranking. HSE’s NOMAD note says sound power and sound pressure differ, often by about 10–20 dB. The ABAC line is 97 dB with no label. The SIP line is 62 dB with no label. Until both pages say which quantity and at what distance, the smaller number is not proof of a quieter machine.
Do the Noise Regulations apply to DIY at home?
No. The Control of Noise at Work Regulations 2005 place duties on employers, not on a householder. Private DIY can still be loud enough to annoy a neighbour and loud enough to matter for your own hearing. The action values are a workplace rule.
When must hearing protection be worn at work?
Employers make hearing protection available at the lower action value of 80 dB(A). Where daily exposure is likely to reach the upper action value of 85 dB(A), and the noise cannot be reduced another way, hearing protection has to be worn. The 87 dB(A) figure is a limit at the ear, taking protection into account. A title decibel is not that assessment.
Are the £299–£360 silent 50 L models actually quiet?
They sit in a higher price band than these four listings, and some print both a sound-pressure figure and a sound-power figure, as Scheppach does with 60 dB Lp(A) and 87 dB Lw(A). That pairing is more honest than a single integer. It is still not a measurement in your garage.
