Second in our guide to air compressors, the Hyundai HY3150SX is a 150-litre, 3HP belt-drive workshop compressor listed at £482.99 for spray painting, air tools, tyre inflation and blowing dust. It carries 4.4 out of 5 from 49 ratings.

The listing disagrees with itself on airflow, which is the figure this guide is built around. The bullets promise a "high airflow of 14CFM". The spec table on the same page gives Air Flow Capacity as "11 Cubic Centimetres Per Minute" — a lower number in a unit that does not describe compressor output at all. The model number is a second mismatch: the product is sold as the HY3150SX, while the Included Components field names an HY3100SX. Nothing on this page comes from our own testing; every figure is quoted from the Amazon listing.

## Questions people ask

**How much air does the Hyundai HY3150SX shift?**

The bullets say a "high airflow of 14CFM". The spec table on the same listing gives Air Flow Capacity as 11 cubic centimetres per minute. Those two figures do not agree, and the second uses a unit that is not used to rate compressor output.

**What size is the tank?**

150 litres. The title, the bullets, the Capacity field and the Tank Volume field all state 150 litres, making it the one headline number the listing keeps consistent.

**What pressure does it run at?**

145psi, which the bullets and the spec table both express as 10 bar.

**How loud is it in use?**

The listing quotes 75dB from a slow-running pump on anti-vibration mounts. One reviewer describes it as not much louder than a vacuum cleaner.

**What comes in the box?**

The Included Components field names an HY3100SX Electric Air Compressor, a user manual and 2 x Euro Quick Release Hose Fittings, even though the product is sold as the HY3150SX. The two model numbers do not match.

**Is it easy to move about?**

The Style field lists it as portable, but the same listing gives the weight as 80kg and the dimensions as 131 x 43 x 92cm. A reviewer who scored manoeuvrability low says it is designed to stay in one place and you would not want to shift it regularly.
