Best 100 litre air compressor
Updated: 21.10.2026
Best only means something once you name the job. The review record on these four amazon.co.uk listings is too thin for a winner, and nobody has lab-tested them for this page. If you want a best 100 litre air compressor for a stated situation, match the machine to noise, labelled airflow, and whether you will check oil. Prices and the full specification table stay on the [100 litre air compressor comparison](/hub/compressors/100l-air-compressor). A quieter oil-free pump with the airflow written on Amazon is a different purchase from a £347.99 lubricated pump stated at 97 dB. Shelf prices below are the figures on those amazon.co.uk listings.

What best can mean here
The vertical SIP Airmate has no amazon.co.uk rating in this capture. The horizontal SIP is 1.0 from one rating, with no review text. The TIGREN is 2.5 from three ratings, again with no review text. The Sealey is 3.7 from three ratings, and the only review text says the compressor arrived broken, was very noisy, and was refunded. A single star, or three stars with one unhappy paragraph, cannot carry a superlative. What the pages do support is a conditional pick: who the listing is for, and who should leave it.
The usable airflow band, once you use free air delivery rather than an unlabelled CFM, is about 7 to 9 CFM. That is a home-garage class. The decision order is on the 100 litre air compressor buying guide. Toolden lists a SIP 05494 100 litre oil-free compressor at 62 dB and 13 CFM free air delivery. That model is not in this comparison. It is context, not a fifth card, and it should not be merged with 05484.
Quietest stated machine in the set
The top pick for a home garage, on the criterion of the lowest stated noise plus free air delivery written on the listing, is the SIP Airmate vertical, model 05484, at £479.98. The amazon.co.uk bullets state 9 CFM free air delivery at 8 bar and 67 dB. The pump is oil-free, the tank is vertical at about 115 cm, and the included lead is 1.3 m with a 13 A plug. There is no owner sample on Amazon to confirm how it behaves after a year, so the pick is the specification, not a pile of reviews.
Skip it when the budget is the constraint. It is the dearest of the four by a clear margin, £84 above the horizontal SIP and about £130 above the TIGREN. Skip it as well if you need a horizontal tank because the ceiling is low. The model-name field says 2 hp while the title says 3 hp (2.2 kW). Use 2.2 kW. A 67 dB catalogue figure is still a class label, not a measurement made in your garage, and it does not by itself feed a tool that wants more than 9 CFM.
The other oil-free SIP
The horizontal SIP Airmate, model 05481, at £395.96 is the oil-free choice when you want to spend less than the vertical model and you have floor space rather than headroom. The listing states 71 dB, 8 bar, 230 V and 13 A. SIP's own page states 9 CFM free air delivery, 71 dB(A) LpA and 90 dB(A) LwA. Amazon's airflow cell says 15 CFM and does not label it as free air delivery. Use 9 CFM. If you size a spray gun on 15 CFM, the tool will be waiting on a pump that the maker describes at 9.
The footprint on Amazon is 47.5 × 97.5 × 79 cm at 56.5 kg. Wheels and warranty are not stated. The 1.0 score from one rating has no text, so you cannot tell whether that star was a courier, a switch, or the noise. Treat it as a warning that the sample is one person, not as a measured failure rate. Skip this listing if you will only believe a number that Amazon itself calls free air delivery, because that label is missing here.
The lubricated pair
The Sealey SAC10030VA at £351.23 and the TIGREN V100DD at £347.99 are the regular-use pair only if you accept a 97 dB class and an oil check. How that oil choice works is on the oil-free or oil page. Sealey's sheet states 7 cfm free air delivery, 97 dB, 1040 × 350 × 720 mm and 48 kg nett. Amazon's title says 13.7 cfm, which is unlabelled, and the page does not state oil, voltage, or a decibel. A quiet operation bullet has no number. The only review text reports a broken arrival, very noisy use, and a refund. Skip the Sealey if you need the Amazon page alone to show oil type, volts, or a real size. The 10 × 10 × 10 mm catalogue line is not a footprint.
The TIGREN is the best value in this set on shelf price, at £347.99, because the listing itself states splash lubrication, 8 bar, 230 V and 97 dB. SIP's page for model 04388 states 8 CFM free air delivery, against 13 CFM unlabelled on Amazon. The score is 2.5 from three ratings with no text. The Amazon model number is SIP-04388. That ties the specification to SIP's sheet. It does not make the TIGREN an oil-free Airmate. Skip both lubricated machines for a terrace or a semi-detached garage against a neighbour's wall. A detached workshop, with hearing protection and someone who will check the oil, is the situation they fit.
Common questions
Which listing states both a low noise figure and free air delivery?
The SIP Airmate vertical, 05484, at £479.98. The bullets state 67 dB and 9 CFM free air delivery at 8 bar. The other three either leave free air delivery to a manufacturer page or, on the Sealey Amazon page, leave the decibel off as well. Low here means the lowest stated figure in this set, not a test we ran.
Which is the lowest price, and what do you give up?
The TIGREN V100DD is £347.99, the lowest shelf price in the saved listings. You give up a quiet class: the listing states 97 dB. You also take an oil-lubricated pump, and you take airflow from SIP's 8 CFM free air delivery rather than from Amazon's unlabelled 13 CFM. The Sealey is only a few pounds more and hides more of the specification on Amazon.
Is the Sealey the quiet one because the bullet says quiet?
No. The bullet has no decibel. Sealey's sheet for the SAC10030VA states 97 dB, which is the same class as the TIGREN listing. The only Amazon review text also calls that compressor very noisy, after it arrived broken and was refunded. Use 97 dB as the working figure.
Can I trust a 1.0 score from one rating?
You can trust that one person left one star. You cannot turn that into a failure rate, because there is no review text and no second opinion. The horizontal SIP's 1.0 from one rating is a thin sample. It is a reason to be cautious, and it is a weak reason to declare the pump faulty.
Who should skip the 97 dB machines?
Anyone buying for a garage that shares a wall with a living room or a neighbour, and anyone who wanted a quiet compressor and then met the Sealey quiet operation line. The 97 dB class is a detached workshop or a workplace where someone has actually assessed the noise. Hearing protection is part of that situation, not an optional extra you discover on the first Saturday.
Is there a quieter 100 litre SIP that is not in this set?
Toolden lists the SIP 05494 as a 100 litre oil-free compressor at 62 dB and 13 CFM free air delivery. It is not one of the four amazon.co.uk listings compared here, so it is not a card on the main page. Mentioning it stops the 67 dB Airmate from being described as the quietest 100 litre SIP on the market.
What must this page refuse to call best?
An unlabelled CFM figure, a quiet bullet with no decibel, a single star with no text, and any claim of a lab winner. The picks above are conditional. The vertical SIP is the top pick when labelled 9 CFM and 67 dB are the priority and the price is acceptable. The TIGREN is the best value when the lowest price matters and 97 dB is acceptable.
